DESKTOP 2051 - GERMANDER SPEEDWELL

Veronica is the largest genus in the flowering plant family Plantaginaceae, with about 500 species. Taxonomy for this genus is currently being reanalysed, with the genus Hebe and the related Australasian genera Derwentia, Detzneria, Chionohebe, Heliohebe, Leonohebe and Parahebe included by many botanists. Common names include speedwell, bird's eye, and gypsyweed.

The species are herbaceous annuals or perennials, and also shrubs or small trees if Hebe is included. Most of the species are from the temperate Northern Hemisphere, though with some species from the Southern Hemisphere. Veronica chamaedrys (Germander Speedwell, Bird's-eye Speedwell - shown below) is a species of Veronica, native to Europe and northern Asia. It is found on other continents as an introduced species.

It is a herbaceous perennial plant with hairy stems and leaves. It can grow to 25 cm tall, but is normally about 12 cm tall. The flowers are blue, with a four-lobed corolla. The form of the leaves are similar to white deadnettle. The 2 to 4 mm wide blossoms of this plant wilt very quickly upon picking, which has given it the ironic name "Männertreu", or "men's faithfulness" in German.

DESKTOP 1556 - VERONICA

Veronica peduncularis (creeping speedwell) is a plant in the plantain family, Plantaginaceae. The ‘Georgia Blue’ Speedwell (USDA Zone: 4-9) was introduced a few years ago from Russia. This creeping speedwell has proven to be an outstanding selection for a bright display in the Spring garden.

Plants form a low creeping mat of deep green leaves, evergreen but turning bronze in the colder months. Small sapphire-blue flowers are studded all over during the spring, and sometimes again in late summer. Perfect for underplanting with spring flowering bulbs of all kinds, particularly miniature Narcissus. Plants may be easily divided in early Autumn. Clip back hard immediately after flowering, to maintain a tight, thick habit.

DESKTOP 1171 - KENILWORTH IVY

Cymbalaria muralis, with common names ivy-leaved toadflax, Kenilworth ivy, coliseum ivy, Oxford ivy, mother of thousands, pennywort, wandering sailor, is a flowering plant native to Mediterranean Europe and widely naturalised elsewhere. It is in the Plantaginaceae family.

It spreads quickly, growing up to 5 cm tall – it commonly grows in rock and wall crevices, and along footpaths. The leaves are evergreen, rounded to heart-shaped, 2.5 to 5 cm long and wide, 3–7-lobed, alternating on thin stems. The flowers are very small, similar in shape to snapdragon flowers. Flowers from May to September in the Northern Hemisphere.

This plant has an unusual method of propagation. The flower stalk is initially positively phototropic and moves towards the light. After fertilisation, it becomes negatively phototropic and moves away from the light. This results in seed being pushed into dark crevices of rock walls, where it is more likely to germinate.

Cymbalaria muralis is native to south and southwest Europe, the southern Alps, eastern Yugoslavia, southern Italy and Sicily. It has spread throughout the world as an invasive plant, including the United States, Australia and the British Isles.

DESKTOP 194 - BEARDTONGUE

Penstemon, the beardtongues, is a large genus of North American and East Asian flowering plants formerly placed in the Scrophulariaceae family (Cronquist system). Due to new genetic research, it has now been placed in the vastly expanded family Plantaginaceae.
 

These plants have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue.
