DESKTOP 2527 - CYMBIDIUM ORCHID
Cymbidium, or boat orchids, is a genus of 52 evergreen species in the orchid family Orchidaceae. It was first described by Olof Swartz in 1799. The name is derived from the Greek word kumbos, meaning 'hole, cavity'. It refers to the form of the base of the lip. The genus is abbreviated Cym in horticultural trade. This genus is distributed in tropical and subtropical Asia (such as northern India, China, Japan, Malaysia, the Philippines, and Borneo) and northern Australia. The larger flowered species from which the large flowered hybrids are derived grow at high altitudes.
Cymbidium plants are sympodial and grow to a height of 60 cm and the racemes as high as 90 cm. The raceme grows from the base of the most recent pseudobulb. Each flower can have a diameter of 5 to 10 cm, according to the species. They bloom during the winter, and each plant can have up to fifteen or more flowers. The fantastic range of colours for this genus include white, green, yellowish-green, cream, yellow, brown, pink, and red [and orange] and black (and there may be markings of other colour shades at the same time), but not blue.
The flowers last about ten weeks. They have a waxy texture. The rounded sepals and petals have about the same dimensions. They show very diverse colour patterns, different for every species. Cymbidium is one of the most popular and desirable orchids in the world because of the beautiful flowers. These plants make great houseplants, and are also popular in floral arrangements and corsages. They have been cultivated for thousands of years, especially in China. Cymbidiums became popular in Europe during the Victorian era. One feature that makes the plant so popular is the fact that it can survive during cold temperatures (as low as 7˚ C or 45˚ F).

DESKTOP 2492 - PANSY ORCHID
Miltonia, abbreviated Milt. in the horticultural trade, is an orchid genus formed by nine epiphyte species and eight natural hybrids inhabitants of the Brazilian Atlantic Forest, one species reaching the northeast of Argentina and east of Paraguay. This genus was established by John Lindley in 1837, when he described its type species, Miltonia spectabilis. Many species were attributed to Miltonia in the past, however, today, the species from Central America and from cooler areas on northwest of South America have been moved to other genera.
Miltonia species have large and long lasting flowers, often in multifloral inflorescences. This fact, allied to being species that are easy to grow and to identify, make them a favourite of orchid collectors all over the world. Species of this genus are extensively used to produce artificial hybrids. Despite the fact that Miltonia is now a well established genus, most of its species were originally classified under other genera as Cyrtochilum, Oncidium, Odontoglossum, and Brassia. All were discovered between 1834 and 1850 with the exception of M. kayasimae, discovered only in 1976.
These epiphytic orchids occur from Central to Southern Brazil down to Argentina. They are named after Charles Wentworth-Fitzwilliam, 5th Earl Fitzwilliam, formerly Viscount Milton, an English orchid enthusiast. These orchids have two leaves, arising from a pseudobulbs, covered with a foliaceous sheath. The inflorescence consists of waxy, nonspurred flowers. The lip is large and flat and lacks a callus at its base. They possess a footless column with two hard pollinia. The flowers have a delicate, exotic scent, some compare to that of roses. The species in this genus are sometimes referred to as the "pansy orchids", but it is the Miltoniopsis orchids that have flowers that closely resemble the pansy. Almost everyone except for the most serious orchid hobbyists use the name pansy orchids interchangeably, which may cause confusion.

DESKTOP 2443 - PEONIES
Peonies are sumptuous flowers that lend themselves to quite spectacular displays in arrangements, especially if complemented by other exotic blooms like orchids. We haven't had much success in growing peonies in our garden, but bouquets are available at florist shops, so we enjoy them when in season.

DESKTOP 1290 - PINK HYACINTH ORCHID
Dipodium roseum, commonly known as pink hyacinth orchid, in the family Orchidaceae is a leafless mycoheterotrophic orchid found in east and south-eastern Australia. The species was formally described in 1991. The type specimen was collected in Montrose in Victoria's Dandenong Ranges. The species was previously included in a wider circumscription of Dipodium punctatum.
For most of the year, plants are dormant and have no above-ground presence. Below the ground lie fleshy roots. Flower spikes ranging from 30 to 90 cm in height appear between December and April. These racemose inflorescences have 15 to 40 pink flowers with small darker spots. The sepals and petals are strongly recurved and the three-lobed labellum is pink with dark lines and a band of mauve hairs. A rare white-flowering form also exists.
Pollination of this species, as for all species in the genus, is by native bees and wasps. No leafless species of Dipodium has been sustained in cultivation due to the inability to replicate its association with mycorrhizal fungi in a horticultural context. I.e. it needs the wild underground fungi to nourish it as it has no leaves and cannot photosynthesise.
