autumn crocus
Colchicum byzantinum
Autumn Crocus is a magical plant that blooms in the fall when most other flowers have past. Also known as Colchicum byzantinum, this fall bloomer is incredibly unique. It starts blooming in August, producing light pink, tulip shaped flowers on tall, thin stems which easily reach up to six inches in height with no leaves. This ensures that the flower stands out from its surroundings. It also produces a yellowish-green foliage that persists throughout the winter. This plant is an amazing addition to any late-season garden and is sure to make a statement!
