autumn crocus
Colchicum autumnale
The Autumn Crocus (Colchicum autumnale) is an amazing plant species due to its beauty and versatility. Despite its appearance, it is neither a true crocus nor an autumn flower, rather it is a member of the lily family. It blooms in late summer and early fall and can grow up to 20 cm in height. Its showy purple flowers are seen as one of its main attractions, and its heart-shaped leaves begin to take on purple tones in cooler weather. This tough plant is also known for its medicinal properties, which include helping lower cholesterol levels and fighting recurring stomach ailments. Overall, the Autumn Crocus is a beautiful and versatile species that needs to be appreciated.
