About
Crocus biflorus 'Blue Pearl' is a compact perennial corm characterized by slender, dark green leaves that reach a height of approximately 8 cm, each displaying a delicate white stripe down the center. From each corm, you can expect to see up to four fragrant flowers emerging in spring. These blooms are light lavender-blue on the outside, revealing a white interior and a yellow throat, coinciding with the leaf growth.
