Appearance and characteristics of hellebore
Hellebore is a perennial plant that holds its foliage all year. Flower stems arise from the centre of the plant in late autumn and early winter to provide flowers for the winter months. The flowers are cup-shaped and semi-pendulous on the stalks, and there can be dozens at a time.
Breeding has produced a stunning array of flower forms and colours, from pure white through to almost completely black. Some flowers are spotted or striped, and others have different-coloured edges. Flowers also come in the original five-petalled form, while other varieties have masses of petals.
Uses for hellebore
Because hellebore flowers in winter, it is a great addition to any garden. Use it to add life to a garden area that is otherwise having a winter rest. The flowers can also be cut and brought inside for a vase.
How to plant and grow hellebore
- The ideal place to grow this perennial is under a deciduous tree, as this gives it plenty of sun in winter and then shades the plant when the leaves grow back on the tree.
- Plant out at any time of the year in a garden bed that has been prepared with added compost. Hellebore will withstand frost and cold, but not humidity.
Caring for your hellebore
Hellebore really doesn’t take much work. Mulch it in the summer months to keep the roots cool. The plant can be fed with a complete garden fertiliser in late autumn to give it a boost for the winter flowers.
How and when to prune a hellebore
You can remove very old leaves that have become ratty by taking them off very close to the ground. Do this in winter when the newer leaves have already emerged.
Diseases and pests affecting a hellebore
Hellebore is rarely troubled by pests or diseases. It is occasionally attacked by aphids, so keep your eye out for these and spray with a garden insecticide if they occur. Make sure you spray the underside of the leaves too, as these pests are often found there.
If grown in too sunny a spot, the leaves can become scorched. In this case, it will be time to relocate the plant to a spot out of summer sun. Do this in late autumn or winter.
Hellebore propagation
Dividing hellebore
As hellebore is an herbaceous perennial, it will form large clumps over time. These can be dug up and divided in late autumn to provide new plants.
Growing hellebore from seed
Hellebore can be grown from seed, but the new plants may have different flowers to the ones you propagate from.
- Collect the black seeds from the pods as soon as they have gone hard.
- Sow them in seedling trays using a seed-raising mix and lightly cover them.
- When the seedlings are large enough, move them into individual pots.
- Plant out after a year. It may take two or three years for the plants to flower from seed.
