Crocus tommasinianus or also known as Early Crocus is from the Iridaceae family of plants which are deciduous perennials that grow from corms. Crocus tommasinianus is an early bloomer it has long tubed flowers with long pointy leaves.
The flowers are usually purple, I saw a lot of them on my early spring walk in Kew Gardens. Crocus tommasinianus is native to Europe and it grows to about 10 cm tall. It grows in the sun and poor to the fertile soil. Squirrels like the corms so watch out!
