DESKTOP 3121 - 'BLUE ANGEL'

Salvia patens 'Blue Angel' is a striking garden plant with delightful blue flowers. Since the 1838 discovery of this herbaceous species from Central Mexico, Salvia patens has been a mainstay of the perennial garden. Blue Angel is one of the smallest of the full-sized varieties of the so-called 'gentian sages'. Well branched and compact, this variety has 6 cm flowers that are a deep, royal blue and bloom from Summer into Autumn.

 

It is a reliable perennial, returning year after year in Zones 8 to 11. However, it is so lovely that it is worth growing as a summer bedding plant in colder zones. Blue Angel likes regular watering and rich, well-drained soil. It grows in full sun or partial shade and can handle moist corners of the garden. Use it as a path edging, border, ground-cover or container plant. British horticulturist Graham Stuart Thomas called Salvia patens 'the best plant in cultivation.'

DESKTOP 2849 - DIEFFENBACHIA

Dieffenbachia is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. It is widely cultivated as an ornamental, especially as a house plant, and has become naturalised on a few tropical islands.

 

Dieffenbachia prefers medium sunlight, moderately dry soil and average home temperatures of 17–27 °C. Indoors it should be watered about twice a week. Dieffenbachia is a perennial herbaceous plant with straight stem, simple and alternate leaves containing white spots and flecks, making it attractive as indoor foliage. Species in this genus are popular as houseplants because of their tolerance of shade. 

 

The flowers are green/white and have the typical spathe of arums. The common name, "dumb canes" refers to the poisoning effect of raphides, which can cause temporary inability to speak. Dieffenbachia was named by Heinrich Wilhelm Schott, director of the Botanical Gardens in Vienna to honour his head gardener Joseph Dieffenbach (1796–1863).

 

With a minimum temperature tolerance of +5 °C, Dieffenbachia must be grown indoors in temperate areas. They need light, but filtered sunlight through a window is usually sufficient. They also need moderately moist soil, which should be regularly fertilised with a proprietary houseplant fertiliser. Leaves will periodically roll up and fall off to make way for new leaves. Yellowing of the leaves is generally a sign of problematic conditions, such as a nutrient deficiency in the soil. Dieffenbachia respond well to hot temperatures and dry climates.

DESKTOP 2800 - EASTER DAISIES

Easter (or Michaelmas) daisies (Aster novi-belgii) were once popular in gardens, but are less frequently seen now. They are herbaceous perennials with upright, much-branched stems on which masses of small daisies are produced in late summer and autumn. The flowers range in colour from white through pale lilac blue, mauve, purple and pink to deep reddish plum. They can be planted in mixed borders and can also be used effectively in beds on their own. The taller varieties often need staking, and are best planted at the back of garden beds.

 

A. novi-belgii was introduced from North America into Britain in 1710. In America they were called New York daisies, however, in England these plants bloomed at the same time as St Michael's Day is celebrated (September 29th), and so they became associated with the festival of Michaelmas and were given its name. In the Southern hemisphere where Easter is an Autumnal feast, the daisies bloom at about this time and hence the term "Easter Daisies".

 

These daisies are easy to grow. Plant them in full sun in a rich, moisture-retentive soil. When they die down in winter cut the dead stems back to ground level. When the new shoots appear in spring, apply a mulch of well-rotted manure or compost to which fertiliser has been added. Lift and divide the clumps every second or third year in winter.

DESKTOP 2786 - DAHLIA

Dahlia is a genus of bushy, tuberous, herbaceous perennial plants native mainly in Mexico, but also Central America, and Colombia. A member of the Asteraceae (=Compositae), dicotyledonous plants, related species include the sunflower, daisy, chrysanthemum and zinnia. There are at least 36 species of dahlia, with hybrids commonly grown as garden plants.

 

Flower forms are variable, with one head per stem; these can be as small as 5.1 cm diameter or up to 30 cm ("dinner plate"). This great variety results from dahlias being octoploids (that is, they have eight sets of homologous chromosomes), whereas most plants have only two. In addition, dahlias also contain many transposons (genetic pieces that move from place to place upon an allele), which contributes to their manifesting such great diversity.

 

The stems are leafy, ranging in height from as low as 30 cm to more than 1.8–2.4 m. The majority of species do not produce scented flowers or cultivars. Like most plants that do not attract pollinating insects through scent, they are brightly coloured, displaying most hues, with the exception of blue. The dahlia was declared the national flower of Mexico in 1963. The tubers were grown as a food crop by the Aztecs, but this use largely died out after the Spanish Conquest. Attempts to introduce the tubers as a food crop in Europe were unsuccessful.

DESKTOP 2779 - DURANTA

Duranta erecta is a species of flowering shrub in the verbena family Verbenaceae, native from Mexico to South America and the Caribbean. It is widely cultivated as an ornamental plant in tropical and subtropical gardens throughout the world, and has become naturalised in many places. It is considered an invasive species in Australia, China, South Africa and on several Pacific Islands.

The genus name is in honour of Castore Durante, a fifteenth-century Italian botanist. The specific epithet erecta means "upright" in Latin. The plant is also known as D. repens, from the Latin for "creeping". The latter name was originally used to identify smaller-leaved varieties of the species. Common names include golden dewdrop, pigeon berry, and skyflower. In Mexico, the native Nahuatl name for the plant is xcambocoché. In Tonga it is known as mavaetangi (tears of departure).

Duranta is registered as an invasive weed by many councils of Australia. It is a prolific, fast growing weed that is spread by birds from domestic areas to natural reserves. It was introduced and marketed as a hedge plant some years ago. Many people now fight to keep this thorny pest under control. It is highly ranked in the most invasive weeds in Australia.

Duranta erecta is a sprawling shrub or (infrequently) a small tree. It can grow to 6 m tall and can spread to an equal width. Mature specimens possess axillary thorns, which are often absent on younger specimens. The leaves are light green, elliptic to ovate, opposite, and grow up to 7.5 cm long and 3.5 cm broad, with a 1.5 cm petiole. The flowers are light-blue or lavender, produced in tight clusters located on terminal and axillary stems, blooming almost all year long. 

The fruit is a small globose yellow or orange berry, up to 11 mm diameter and containing several seeds. The leaves and berries of the plant are toxic, and are confirmed to have killed children, dogs and cats. However, songbirds eat the fruit without ill effects. The cultivar illustrated is the hybrid "China Girl".

DESKTOP 2709 - SUNFLOWER

Helianthus x multiflorus 'Flore Pleno' is a robust, perennial plant that produces double yellow flowers throughout the summer. Its deep green foliage is an excellent screen or foil to showcase small plants. Flowers of Helianthus x mult. 'Flore Pleno' are scattered all throughout this "green wall" which makes it an excellent choice for the back of your border.

This is a good plant for cut flowers and blooms for 4 weeks or more. It can be planted in containers and attracts butterflies. Prefers average, neutral to slightly alkaline soil. Well drained soil is good for overwintering, but give Helianthus a good soaking if August begins to overpower. Can be divided in spring every 3-4 years. Cut back by one-half in early to midsummer to prevent staking.

DESKTOP 2653 - ALSTROS

Alstroemeria, commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America although some have become naturalised in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centres of diversity, one in central Chile, the other in eastern Brazil.

Species of Alstroemeria from Chile are winter-growing plants while those of Brazil are summer-growing. All are long-lived perennials except A. graminea, a diminutive annual from the Atacama Desert of Chile. The genus was named after the Swedish baron Clas Alströmer (1736 – 1794) by his close friend Carolus Linnaeus.

Many hybrids and at least 190 cultivars have been developed, featuring many different markings and colours, including white, yellow, orange, apricot, pink, red, purple, and lavender. The most popular and showy hybrids commonly grown today result from crosses between species from Chile (winter-growing) with species from Brazil (summer-growing). This strategy has overcome the florists' problem of seasonal dormancy and resulted in plants that are evergreen, or nearly so, and flower for most of the year. This breeding work derives mainly from trials that began in the United States in the 1980s.

The flower, which resembles a miniature lily, is very popular for bouquets and flower arrangements in the commercial cut flower trade. Most cultivars available for the home garden will bloom in the late spring and early summer. The roots are hardy to a temperature of −5 °C. The plant requires at least six hours of morning sunlight, regular water, and well-drained soil.

WILD PLUM

Prunus americana, commonly called the American plum or wild plum, is a species of Prunus native to North America from Saskatchewan to New Mexico east to New Hampshire and Florida. It has often been planted outside its core range and sometimes escapes cultivation. Many cultivated varieties have been derived from this species. It forms an excellent stock upon which to graft the domestic plum.

The wild plum grows as a large shrub or small tree, reaching up to 4.6 m. It is adapted to coarse- and medium-textured soils, but not to fine soils. The shrub is winter-hardy, but has little tolerance for shade, drought, or fire. Its growth is most active in spring and summer, and it blooms in midspring. It propagates by seed, but the rate of spread by seed is slow. 

The wild plum is used for both ornamental and culinary purposes. The white flowers are decorative in spring and its short, single leader makes it a popular residential landscape tree. Sargent says of it: "As an ornamental plant P. americana has real value; the long wand-like branches form a wide, graceful head which is handsome in winter and in spring is covered with masses of pure white flowers followed by ample bright foliage and abundant showy fruit.

DESKTOP 2506 - ECHINACEA

Echinacea is a genus of herbaceous flowering plants in the daisy family, Asteraceae. The nine species it contains are commonly called purple coneflowers. They are endemic to eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas.

They have large, showy heads of composite flowers, blooming from early to late summer. The generic name is derived from the Greek word ἐχῖνος (echinos), meaning "sea urchin," due to the spiny central disk. Some species are used in herbal medicines and some are cultivated in gardens for their showy flowers. A few species are of conservation concern.

DESKTOP 2471 - POTATO BUSH

Lycianthes rantonnetii (blue potato bush) is a species of flowering plant in the family Solanaceae. It is native to Brazil, Bolivia, Argentina and Paraguay. It is cultivated as ornamental plant the world over. The blue potato bush is one of about 150 species in the genus Lycianthes, which are found mostly in tropical regions of the Americas, and others located in the Asia-Pacific region.

Lycianthes is apparently closely related to the chili peppers (Capsicum). However, it was long confused with the nightshades (Solanum), and several little-known Solanum species presumably should be included with Lycianthes. The species is named for Barthélémy Victor Rantonnet, a 19th-century French horticulturalist. 

This plant is noted for its superb display of richly coloured and lightly fragrant flowers over a long season, provided it is grown in full sun. Water and feed regularly for the best display. Cuttings will make good-sized bushes for the following summer. The small red autumn berries are poisonous when ingested.

DESKTOP 2450 - BLUE GINGER

Dichorisandra thyrsiflora or Blue Ginger is a tropical plant which resembles ginger in growth and habit, but is actually related to the spiderworts (the genus Tradescantia). The plant is native to the tropical woodlands of North, Central and South America, specially in Atlantic Forest vegetation in Brazil. Of the family Commelinaceae, they are cultivated for their handsome spotted stems, large shiny foliage which is held horizontally, surmounted by striking blue flowers.

The plant was first described by the naturalist Johann Christian Mikan in 1823. It was first grown in England in 1822, and is recorded from Sir William MacArthur's catalogue in 1857 of plants he grew in Camden southwest of Sydney. It has become naturalised in a small region of northeastern New South Wales in Australia. It is best grown in partial shade, sheltered from hot afternoon sun in summer and protected from strong winds that can damage the tall stems. It generally blooms in autumn.

The beautiful clustered flower heads are vibrant purple-blue and appear atop of spiralled, ginger-like stems of leaves, which often have purplish undersides. It needs fertile soil and reasonable moisture in the warmer months. It is very frost sensitive. It is best to cut the stems back after flowering. It is propagated by division or root or stem cuttings.

DESKTOP 2415 - TORCH GLOW

Bougainvillea ‘Torch Glow,’ stands on its own amidst the many garden bougainvilleas due to its unique, upright, shrubby form. Bougainvilleas are technically lianas, tropical shrubs with reaching stems that grow into the treetops of their jungles of origin. Yet this selection was discovered in California among a group of seedlings imported from the Philippines. Ordinary plants have fast-growing stems with widely spaced leaves. The leaves of ‘Torch Glow’ are tightly packed together on their branches, which are shortened, resulting in a compact habit, a true a true shrub for the landscape, very different from the massive vines of many bougainvilleas.

At the tips of its short branches, ‘Torch Glow’ blooms in bright magenta bracts densely packed among yellow green leaves. Bracts are modified leaves evolved to lure pollinators to the nearly insignificant true flowers nestled among them. These small, white tubular blooms are pollinated by hummingbirds. Grow ‘Torch Glow’ in full sun on well-drained, even slightly dry soil. Too much fertiliser and water can reduce the show of colour. Plant with care because it is sensitive to root disturbance. It will not transplant once in the ground. This upright form makes a fine foundation plant or a specimen focal point in the dry garden. The range of uses is almost endless.

DESKTOP 2331 - CHOISYA

Choisya is a small genus of aromatic evergreen shrubs in the rue family, Rutaceae. Members of the genus are commonly known as Mexican orange or mock orange due to the similarity of their flowers with those of the closely related orange, both in shape and scent. They are native to southern North America, from Arizona, New Mexico, Texas and south through most of Mexico. In its generic name Humboldt and Bonpland honoured Swiss botanist Jacques Denis Choisy (1799-1859).

The species grow to 1 to 3 m tall. The leaves are opposite, leathery, glossy, palmately compound with 3-13 leaflets, each leaflet 3–8 cm long and 0.5–3.5 cm broad. C. ternata (shown here) has three broad leaflets, while C. dumosa has up to 13 very narrow leaflets. The flowers are star-shaped, 3–5 cm diameter, with 4-7 white petals, 8-15 stamens and a green stigma; they are produced throughout the late spring and summer. The fruit is a leathery two to six sectioned capsule.

Choisya species are popular ornamental plants in areas with mild winters, grown primarily for their abundant and fragrant flowers. The foliage is also aromatic, smelling of rue when bruised or cut. The most commonly found cultivars in the horticultural trade are the species, C. ternata, the golden-leaved C. ternata 'Sundance', and the inter-specific hybrid C. 'Aztec Pearl' (C. arizonica x C. ternata). All three varieties have gained the Royal Horticultural Society's Award of Garden Merit. The flowers are also valued for honeybee forage, producing abundant nectar.

DESKTOP 2317 - HYDRANGEA

Hydrangea (common names hydrangea or hortensia) is a genus of 70-75 species of flowering plants in the Hydrangeaceae family, native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. 

They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. Having been introduced to the Azores, H. macrophylla is now very common, particularly on Faial, which is known as the "blue island" due to the vast number of hydrangeas present on the island. Species in the related genus Schizophragma, also in Hydrangeaceae, are also often known as hydrangeas. Schizophragma hydrangeoides and Hydrangea petiolaris are both commonly known as climbing hydrangeas.

DESKTOP 2177 - PETUNIA

Petunia is genus of 35 species of flowering plants in the family Solanaceae, of South American origin, closely related to tobacco, cape gooseberries, tomatoes, deadly nightshades, potatoes and chili peppers. The popular flower of the same name derived its epithet from the French, which took the word petun, meaning "tobacco," from a Tupi–Guarani language.

An annual, most of the varieties seen in gardens are hybrids (Petunia × hybrida). Here is one of the Surfinia series of petunia, called 'Purple Vein'. It is perfect for creating colourful summer displays in containers and hanging baskets. It is also a good ground cover plant, making a carpet of lavender blooms with contrasting veins. For the best displays, feed and water regularly.

DESKTOP 2093 - CALIFORNIAN POPPY

Eschscholzia californica (Californian poppy, golden poppy, California sunlight, cup of gold) is a species of flowering plant in the family Papaveraceae, native to the United States and Mexico, and the official state flower of California. It is a perennial or annual growing to 13–152 cm tall, with alternately branching glaucous blue-green foliage. The leaves are alternately divided into round, lobed segments.

The flowers are solitary on long stems, silky-textured, with four petals, each petal 2 to 6 cm long and broad; flower colour ranges from yellow to orange, with flowering from February to September. The petals close at night or in cold, windy weather and open again the following morning, although they may remain closed in cloudy weather. The fruit is a slender, dehiscent capsule 3 to 9 cm long, which splits in two to release the numerous small black or dark brown seeds. It survives mild winters in its native range, dying completely in colder climates.

E. californica is drought-tolerant, self-seeding, and easy to grow in gardens. It is best grown as an annual, in full sun and sandy, well-drained, poor soil. Horticulturalists have produced numerous cultivars with a range of colours and blossom and stem forms. These typically do not breed true on reseeding. Seeds are often sold as mixtures. Many cultivars have gained the Royal Horticultural Society's Award of Garden Merit. Because of its beauty and ease of growing, the California poppy was introduced into several regions with similar Mediterranean climates.

It is commercially sold and widely naturalised in Australia, and was introduced to South Africa, Chile, and Argentina. It is recognised as a potentially invasive species within the United States, although no indications of ill effects have been reported for this plant where it has been introduced outside of California. The golden poppy has been displaced in large areas of its original habitat, such as Southern California, by more invasive exotic species, such as mustard or annual grasses.

DESKTOP 2079 - PONTEDERIA

Pontederia cordata, common name pickerelweed (USA) or pickerel weed (UK), is a monocotyledonous aquatic plant native to the American continent. It grows in a variety of wetlands, including pond and lake margins across an extremely large range from eastern Canada south to Argentina. A few examples include northern rivers, the Everglades and Louisiana. The species grows as an emergent plant, that is, in flooded conditions, so the plant is generally dependent upon aerenchyma in the stem to carry oxygen into the roots. Its metabolism, is, however, also tolerant of low soil oxygen.

It is often found in areas where water levels fluctuate naturally, with spring flooding and later summer emergence. Apart from flooding, the species is also influenced by soil fertility, tending to grow in the more fertile bays of large lakes, for example. Like many aquatic plants, it is negatively affected by salinity and grazing. It is also negatively affected by competition from other wetland plants. Like many wetland plants, it can survive unfavourable conditions as buried seeds in the soil.

The plant flowers in late summer. The purple flowers have yellow markings which may assist in attracting bees for pollination. One bee species known to pollinate the flowers is Dufourea (Halictoides) novaeangliae. Once the plant begins to produce seeds, the stem supporting the inflorescence bends to submerse the fruits and seeds. Seeds are dormant at the time of dispersal and will not germinate without stratification for 6-8 weeks.

DESKTOP 2065 - COUROUPITA

Couroupita guianensis, known by several common names, including cannonball tree, is a deciduous tree in the family Lecythidaceae, which also contains the Brazil nut (Bertholletia excelsa). It is native to the rainforests of Central and South America. The tree grows up to 35 metres in height. The clustered leaves vary in length, generally from 8 to 31 cm, but reaching up to 57 cm.

The fragrant flowers are borne in large bunches up to 80 meters long. Some trees flower profusely, until the entire trunk is buried in flowers. One tree can bear 1000 flowers per day. They are strongly scented, especially at night, and in the early morning. They are large, up to 6 cm wide, and often brightly coloured, the six petals in shades of pink and red near the bases and yellowish toward the tips. There is a ring of stamens at the centre, and an arrangement to stamens that have been modified into a hood.

The large fruit, which is woody and very spherical, measuring up to 25 cm wide, gives the species the common name “cannonball tree”. A smaller fruit contains perhaps 65 seeds, while a large one can have 550. One tree can bear 150 fruits. The fruit takes up to a year to mature in most areas, sometimes as long as 18 months.
