Giant Heartleaf Lily Seeds
 
(Cardiocrinum cordatum var. glehnii)
 
The Giant Heartleaf Lily is a true woodland marvel, revered for its enormous, heart-shaped leaves and towering flower spikes crowned with large, trumpet-shaped white blooms delicately brushed with green and purple veining. Native to cool, forested regions of northern Japan and the Russian Far East, this plant feels ancient, stately, and almost mythical in presence.
 
Unlike ordinary lilies, Cardiocrinum grows slowly and deliberately, forming a dramatic rosette of lush foliage before eventually sending up a breathtaking floral tower that can reach 6–8 feet tall. The flowers are lightly fragrant, especially in the evening, and attract pollinators while lending a serene, woodland elegance to shaded gardens.
 
This is a plant for patient gardeners and collectors, one that rewards time with a once-in-a-generation bloom and a sense of quiet grandeur rarely found in modern gardens.
