Colchicum

life science Maturity 5-7 Next article →

Colchicum is a group of beautiful flowering plants. There are about 160 different species in this genus. These plants grow from thick parts under the soil called corms. You can think of a corm like a special bulb. Many people call these plants "naked lady" or "autumn crocus." This name comes from how they grow each year. The flowers pop up in late summer or autumn. However, the green leaves do not appear until the spring. This makes the flowers look like they are standing all alone.

These plants have a very interesting way they work. In most flowers, the ovary is easy to see. In Colchicum, the ovary stays hidden underground. Because the ovary is so low, the styles must be very long. A style is a thin part of the flower. These styles can grow to be more than 30 millimeters long.

This helps the flower reach up toward the air. You can also tell them apart from crocuses by looking closely. Colchicum has three styles and six stamens. Crocuses have only one style and three stamens.

People have known about these plants for a very long time. The name Colchicum comes from an ancient place. It comes from Colchis, which was the Greek name for a region in Georgia. This area is in the Caucasus mountains. In Greek myths, this was where the Argonauts went to find the Golden Fleece. Scholars think the name might come from an even older word, Qulha.

This history connects these simple flowers to very old stories.

Colchicum plants are found in many different parts of the world. They grow in West Asia and Europe. You can also find them near the Mediterranean coast. Some grow all the way down the East African coast to South Africa. Many types are grown in gardens as pretty flowers. Some famous types include Colchicum autumnale and Colchicum speciosum. Some even have special awards from the Royal Horticultural Society. In the United Kingdom, a special collection is kept at Felbrigg Hall in Norfolk.

Even though they are pretty, you must be very careful with them. All species in this group are toxic. This means they are poisonous if you eat them. They contain a substance called colchicine. Doctors use this drug to treat gout and Familial Mediterranean fever. However, the leaves, seeds, and corms are all dangerous to touch or eat. The plant called Colchicum autumnale has the most lethal amount of this poison.

It is important to admire them with your eyes only.
