Cardiocrinum cordatum, commonly known as Heartleaf Lily, is a deciduous or semi-deciduous perennial bulb native to the cool, moist woodlands and forest margins of East Asia, particularly in Japan and the South Kuril Islands. It can reach a height of 5-6 feet (1.5-1.8 meters) and a width of 2 feet (0.6 meters). The Heartleaf Lily is notable for its large, heart-shaped leaves and tall flower spikes that bear fragrant, trumpet-shaped flowers. The flowers are typically cream to white with a purple throat and bloom in the summer, providing a showy display.

The Heartleaf Lily is valued for its striking foliage and elegant flowers, making it a popular choice for woodland gardens, shaded borders, and as a focal point in semi-shaded areas. It thrives in humus-rich, well-drained soil and prefers part shade to full shade, mimicking its native understory conditions. While it requires consistent moisture, it is important to avoid waterlogged conditions. After flowering, the plant often goes dormant, and the bulb can remain in the ground to re-emerge the following spring. It is generally pest-free but can be susceptible to slug and snail damage.CC BY-SA 4.0
