The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.
Hoheria is a genus of six species of flowering plants in the family Malvaceae. All are endemic to New Zealand. The genus name is a latinization of the Māori language name, houhere. That name, as well as lacebark and ribbonwood, are often used as common names. The name lacebark comes from the lace-like fibrous inner bark layer.
Symphyotrichum ericoides, known as white heath aster, frost aster, or heath aster, is a species of flowering plant in the family Asteraceae native to much of central and eastern North America. It has been introduced to parts of Europe and western Asia.
Veronica peduncularis, the creeping speedwell, is a flowering plant in the plantain family, Plantaginaceae. Listed under its synonym Veronica umbrosa, its cultivar 'Georgia Blue' has gained the Royal Horticultural Society's Award of Garden Merit.
Symphyotrichum pilosum, commonly called hairy white oldfield aster or frost aster, is a flowering plant in the family Asteraceae native to central and eastern North America. It is a perennial, herbaceous plant that may reach 20 to 120 centimeters tall. Its flowers have white ray florets and yellow disk florets.
Penstemon newberryi is a species of penstemon known by the common name mountain pride or Newberry's penstemon. It is native to the mountains of northern California, Oregon, and Nevada, where it grows in rocky habitat, often at high elevation, such as talus. It is a bushy, mat-forming subshrub growing up to 30 centimeters tall. The leaves are mostly basal on the plant, oblong or oval and toothed, measuring 1 to 4 centimeters in length, with a few smaller pairs along the stem. The glandular inflorescence bears showy magenta flowers 2 to over 3 centimeters in length. The flower is generally tubular or funnel-shaped and has a coating of short to long and curly hairs in the mouth and on the staminode.
Veronica prostrata, the prostrate speedwell or rock speedwell, is a species of flowering plant in the family Plantaginaceae, native to Europe. Growing to 10–15 cm (4–6 in) tall, it is a temperate semi-evergreen prostrate perennial plant. As it forms a mat of foliage, it is suitable for groundcover or in the alpine garden. Blue flowers are borne in summer, in terminal racemes above paired leaves.
Hebe odora, known as the Boxwood hebe, Mountain-box, ‘Veronica odora’ or ‘Hebe buxifolia’, is a plant in the family Plantaginaceae, and it is native to New Zealand. Hebe is the most abundant flowering plant genus in New Zealand, and it is an important part of New Zealand's natural landscape. Hebe odora was discovered on the Auckland Islands by J.D Hooker in 840. A certain amount of confusion later arose following its collection on mainland New Zealand by Ernst Dieffenbach and its naming as Hebe buxifolia by George Bentham. Even overseas, Hebe odora is still not infrequently known as Hebe buxifolia. Hebe and its relatives probably evolved from within the Veronica complex of the Northern hemisphere. In fact, until the 1920s, plants in Hebe were considered to be species of Veronica.
Veronica perfoliata, commonly known as digger's speedwell, is a common perennial herb found at higher altitudes in south-eastern Australia. It is a low-growing multi-stemmed plant rising from a woody rootstock. It has rounded blue-grey foliage and sprays of intense violet-blue flowers at the end of arching branches. It is occasionally cultivated as a garden plant.
Veronica austriaca, the broadleaf speedwell, large speedwell, Austrian speedwell, or saw-leaved speedwell, is a species of flowering plant in the plantain family Plantaginaceae, native to northern temperate Europe. Growing to 90 cm (35 in) tall by 60 cm (24 in) broad, it is a mound-forming herbaceous perennial, with deeply toothed leaves and erect spikes of bright blue flowers throughout summer.
Caladenia alpina, commonly known as the mountain caladenia, is a plant in the orchid family Orchidaceae and is native to subalpine areas of south-eastern Australia and to New Zealand. It has a single fleshy leaf and a thin wiry flowering spike bearing two white flowers with red bars on the labellum. In New Zealand this orchid is sometimes known as Caladenia lyallii.
Hoheria lyallii, the mountain lacebark, is a species of flowering plant in the mallow family Malvaceae, native to New Zealand, where it grows on drier mountainous areas of South Island - mainly in eastern Canterbury and Marlborough. Growing to 7 m (23 ft), it is a deciduous shrub or small tree with hairy leaves and slightly scented white flowers in summer. The Latin specific epithet lyallii honours the Scottish naturalist and explorer David Lyall (1817-1895). In cultivation in the UK this plant has gained the Royal Horticultural Society’s Award of Garden Merit. Hoheria lyallii and Hoheria glabrata are known in Māori as houi, and were likely used as textiles by South Island Māori.

Veronica rakaiensis, the Rakai hebe, is a species of flowering plant in the family Plantaginaceae, native to the South Island of New Zealand. As its synonym Hebe rakaiensis it has gained the Royal Horticultural Society's Award of Garden Merit.
Veronica topiaria, the topiarist's hebe, is a species of flowering plant in the family Plantaginaceae, native to the South Island of New Zealand. As its synonym Hebe topiaria it has gained the Royal Horticultural Society's Award of Garden Merit.
Veronica vernicosa, the varnished hebe, is a species of flowering plant in the family Plantaginaceae, native to the South Island of New Zealand. As its synonym Hebe vernicosa, it and its cultivar 'Mrs Winder' have both gained the Royal Horticultural Society's Award of Garden Merit.

Veronica incana, the silver speedwell, is a species of flowering plant in the family Plantaginaceae. It is native to parts of Eastern Europe and Russia, all of Siberia, Mongolia, and northern China, and has been introduced to Czechoslovakia. A number of authorities consider it to be a subspecies of the spiked speedwell Veronica spicata; Veronica spicata subsp. incana. It is a parent of the hybrids Veronica × czemalensis and Veronica × grisea.
