Perennial plants are herbaceous plants which die back to the ground during winter and grow back in spring. Some can be left undisturbed for years while others need to be divided every few years to maintain their vigour. You can find a perennial plant for any situation, whether it's a stone wall or a shady corner. Some are grown for their flower displays, others for their beautiful foliage. Evergreen perennials and half-shrubs are included in this category.
Verbascum - Mullein
Verbascum is a genus of around 360 species in the family Scrophulariaceae. Most species are native to SE-Europe and W-Asia. Most grow in sandy, gritty soil, but can grow in well drained garden soil. They need a sunny, sheltered place.
Veronica is the largest genus of the family Plantaginaceae, with roughly 500 species. The genus is currently in revision and a number of genera could be moved to the Veronica genus, among them the genus Hebe which is almost exclusive to New Zealand. Most species currently in the Veronica genus are native to northern temperate regions. They grow best in sun and any garden soil, although low growing species prefer well drained soil. A few species are native to Iceland. (*)
Vinca - Periwinkle
Vinca is a small genus in the family Apocynaceae native to Europe, NW-Africa and SE-Asia. They are herbaceous plants or subshrubs, ground covers, some very shade tolerant.
Viola - Violets
Viola is the largest genus in the violet family, Violaceae, distributed around northern temperate regions. There are a few species native to the southern hemisphere, in the Andes mountains and Australia. Most are low growing herbaceous plants, although a few are shrubby. A few species in the Andes have thick, water storing leaves. The most widely grown members of the genus are pansies and violets grown as annual flowers, but a few perennial species are grown in gardens. Five species are native to Iceland.
Waldsteinia - Barren strawberries
Waldsteinia is a small genus in the rose family, Rosaceae, native to the northern hemisphere. A few species are grown as shade tolerant ground covers in gardens.
