Spindle (Euonymus): Types and Care in the Garden and at Home

Spindle (Euonymus) is one of the most underrated garden shrubs. For most of the year it is modest, but in autumn it bursts into crimson or pink foliage and is decorated with unusual seed capsules that look like tiny lanterns. Evergreen variegated varieties brighten the garden in winter too. Here are the main types of spindle, how to choose one for the garden or home, how to care for it and why its bright fruit should never be trusted.

What spindle is

Euonymus is a genus of shrubs and small trees in the spindle family, with more than a hundred species. They grow in Europe, Asia, North America and Australia. In Ukraine, European spindle and warty spindle grow wild in woods and along woodland edges.

Spindle's main ornamental features are its vivid autumn colour and its fruit: four-lobed capsules in pink, red or cream split open to reveal seeds wrapped in a fleshy orange coat. They stay on the branches into winter.

A curious historical fact: the bark and roots of warty and European spindle contain gutta-percha, an elastic, rubber-like substance. In the 20th century there were attempts to extract it industrially for insulating cables, but today spindle is valued above all as an ornamental plant.

Popular species and varieties

• European spindle — an easy shrub or small tree with pink capsules and red autumn leaves. Suits informal groups and woodland edges.
• Winged spindle — a compact bush with corky ridges on its stems and one of the brightest autumn colours of any garden plant: the leaves turn crimson.
• Fortune's spindle — a trailing evergreen with variegated white-green or yellow-green leaves, used as ground cover, for edging and in containers.
• Japanese spindle — an evergreen with glossy, leathery leaves. In Ukraine it grows well in the south; elsewhere it is often kept as a houseplant or in containers.

Spindle in the garden

• Position. Sun or partial shade. Autumn colour is brighter in sun; in shade the leaves stay green longer.
• Soil. Almost any except waterlogged; ideally fertile, well-drained, neutral to slightly alkaline.
• Planting. In spring or early autumn, without burying the root collar.
• Watering. Regular for young plants; established shrubs tolerate short dry spells.
• Pruning. Spindle takes clipping well, making it good for hedges and topiary. Do formative and sanitary pruning in early spring.
• Hardiness. European, warty and winged spindle are hardy throughout Ukraine. Fortune's spindle benefits from a blanket of snow or leaves in cold areas, and Japanese spindle overwinters reliably outdoors only in the south. For more tough shrubs, see frost-hardy plants.

Japanese spindle indoors

As a houseplant, Japanese spindle likes bright light and a cool winter rest at 8–12 °C; in a warm room it drops its leaves in winter. In summer it can go out on a balcony. Water moderately; repot young plants yearly and mature ones every 2–3 years. In warm, dry air it often gets scale insects and spider mites.

Pests and diseases

• Spindle ermine moth — caterpillars cover branches in webbing and strip the leaves in early summer. Cut out the webs early and treat if needed.
• Scale insects — brown "scales" on the stems of evergreen species.
• Powdery mildew — a white coating on leaves in crowded plantings.

European spindle is also an overwintering host of the black bean aphid, so it is worth checking in spring if it grows near a vegetable garden.

Warning: the fruit is poisonous

Spindle's bright capsules look tempting, but all parts of the plant, especially the seeds and fruit, are poisonous to people and pets. Poisoning can cause vomiting, abdominal pain and heart rhythm problems. If you have young children, explain that the fruit must not be eaten and don't use fruiting branches in children's crafts. If poisoning is suspected, seek medical help immediately.

Spindle in floristry

Branches with fruit and autumn leaves are a striking material for autumn arrangements, wreaths and bouquets. They stay decorative for a long time and combine well with chrysanthemums, roses, grasses and dried flowers. The evergreen variegated shoots of Fortune's spindle are used as foliage in winter arrangements. For seasonal decor ideas, see flowers in interior design.

Frequently asked questions

Is spindle poisonous?

Yes, all parts of the plant, especially the fruit and seeds, are toxic to people and animals.

Why doesn't my spindle turn red in autumn?

Usually because it is in shade: the brightest colour develops in sun. It also depends on the species — winged spindle colours most vividly.

Can spindle be grown from cuttings?

Yes, semi-ripe cuttings taken in summer root well in a moist medium.

Which spindles are evergreen?

Fortune's spindle and Japanese spindle.
