About
Crocus korolkowii is a compact, perennial corm that generates slender green leaves reaching up to 10 cm in length, each featuring a delicate white stripe down the center. During late winter and early spring, it produces elongated, aromatic flowers in a golden yellow hue, with many outer petals displaying subtle feathering in purple or deep brown.
