Description

Colchicum speciosum is a vigorous grower and does well in full sun to partial shade and well-drained soils in most climates. It is valued in gardens for its late flowering at the end of summer and into autumn.

Colchicum speciosum is a species of flowering plant in the family Colchicaceae, native to mountainous areas of northern Turkey, the Caucasus and northern Iran. Growing to 18 cm (7 in) tall by 10 cm (4 in) wide, it is an herbaceous perennial growing from corms. C. speciosum blooms in the fall, producing reddish/violet flowers on stems up to 30 centimetres (12 in) tall without any leaves present. The strap-like leaves grow in the spring, then yellow, wither and die back as summer progresses. The flowers strongly resemble those of the crocus, the familiar spring-flowering bulb; hence the common name autumn crocus which is applied to this and other colchicum species.

Note: Ornamental use only. Many plants have poisonous parts, these included. These seeds and plants are poisonous.

Hardiness zones: 5-9

Seeds per pack: 3

Germination: Start these seeds right away for best germination rates. Start indoors. Your planting container should have holes in the bottom for excess water to drain. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination is generally 30-60 days after the warming period, though some can take longer.
