Colchicum autumnale aka Autumn Crocus

Taxonomy ID: 4537

Colchicum autumnale, also known as autumn crocus, meadow saffron, or naked ladies, is a toxic autumn-blooming plant that resembles true crocuses but belongs to the Colchicaceae family, unlike the crocuses that belong to the Iridaceae family. The name "naked ladies" refers to the flowers emerging before the leaves. Despite being called "meadow saffron," this plant is not the source of saffron, which is obtained from the saffron crocus. It is cultivated as an ornamental despite its toxicity. One popular cultivar, 'Nancy Lindsay,' has received the Royal Horticultural Society's Award of Garden Merit. 'Nancy Lindsay' is a small perennial with corms, growing up to 15cm in height. It produces up to 5 deep mauve-pink flowers, each measuring 5cm across, with faint netting on the outside of the tepals.

What is the sunlight requirement for Autumn Crocus

Autumn Crocus requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Autumn Crocus will be sure to bring you many years of beauty and enjoyment.

How to fertilize Autumn Crocus

The Autumn Crocus should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Is Autumn Crocus toxic to humans/pets?

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.
