Colchicum- Autumn Crocus, Meadow Saffron

Autumn-flowering bulbous plant; the flowers resemble a giant crocus. The entire plant is extremely poisonous, also to cattle.

Situation:

Worth growing in an autumn garden; its colour goes well with dropping leaves. Likes sun or partial shade; they will often multiply naturally.

Soil:

Requires rich, moist soil.

Propagation:

The common species from seed; hybrids from offsets.

Colchicum autmnale: common autumn crocus: Height 15-20 cm, flowering season late summer to mid autumn; lilac-pink or lilac-red flowers. The foliage appears in spring. ‘Albiflorum’ has white flowers; ‘Purpureum’, deep purple.

Colchicum hybrids: A group with very large flowers, eg ‘The Giant’, deep lilac; ‘Violet Queen’, purple violet; and ‘Waterlily’, lilac double-flowered, which resembles a waterlily. compost – anything that is humus rich. Culture On a smooth wall the plants cannot get a hold; they must therefore be trained and tied in. All species and hybrids flowering after early summer may be cut down in spring to 70-100 cm from the ground. Other climbers must only be thinned out a little after flowering.

Propagation:

The herbaceous plants may be increased from seed or by division. Layering is the simplest method to propagate climbers.
