Winter Gardening – Perennial Winter Plants Helleborus, Ophiopogon and Phormium

Most perennial winter plants are dormant in winter and start shooting out of the ground in spring, so the ones that do flower in winter are eye-catching. The following provides an exciting glimpse of what can be grown in the winter garden when many plants are resting.

Helleborus

This is an important genus from the gardener’s point of view, with many desirable plants, all with nodding flowers and handsome, more or less evergreen leaves. They are indispensable in the winter garden. All Hellebores thrive in the shade of deciduous trees and shrubs and will even tolerate heavy shade next to a wall. They are easy to grow in any fertile, well-drained soil in sun or shade such as window boxes.. All are poisonous.

The Corsican hellebore that tolerates drier conditions than most other members of the genus. The firm, jade-green leaves, which have toothed leaflets, are attractive throughout the year. The clusters of apple-green, cup-shaped flowers appear in late winter and last until early spring.

Helleborus foetidus – Bear’s foot or stinking hellebore

Bear’s foot or stinking hellebore is a dramatic species, which makes a clump of dark-green leaves. Strong stems carrying many bell-shaped, apple-green flowers appear in mid-winter to mid-spring. It looks good with snowdrops.

Helleborus niger

The Christmas rose is one of the prettiest and most desirable of the hellebores, but unfortunately, it is also one of the trickiest to grow. It has dark-green, basal, leathery leaves and large, glistening, cup-shaped white flowers in the early winter garden. The flowers are sometimes flushed with pink, with greenish-white centres, ageing to pinkish-white. It is slow to establish and needs fertile, sticky soil that does not dry out.

Helleborus orientalis

The Lenten rose, an Eastern Mediterranean species, is one of the easiest hellebores to grow and is also one of the most variable species. The flowers, which appear from late winter into spring, can be white, yellowish-cream, dusky-pink, clear glowing red or plum-purple. All are flushed green inside and out. The leaves are also handsome: firm and with serrated edges, and in shades of green, paler leaves being associated with paler flower colours.

Ophiopogon –  Black Mondo grass

The species, Ophiopogon planiscapus is rarely grown: it is a grass-like plant with dull, deep-green leaves and small, bell-shaped, pale pinkish-purple summer flowers, and produces small black berries in autumn. The plant spreads slowly by stolons. For the most impact, grow it in gravel or in containers. It is especially effective in Japanese-style planting.

Phormium

Originally from New Zealand, phormiums look exotic but are frost hardy. Being evergreen, they add interest throughout the year. Phorimium tenax “Rainbow Queen” has a wide range of colours with its sword-like leaves ranging from pink and lemon to orange and bronze. It requires sun and moist soil.
