The genus Cardiocrimun is considered here because its members are mostly cultivated like a lily and often planted with them. The heart-shapedof Cardiocrimini have given rise to the name of this genus.

C. cordatum Makino 1913.
Widely distributed throughout the three main Japanese islands, and also in Sakhalin and the Kuril Islands.
The, 4-8 feet tall, bears a whorl of long-petiolcd, heart-shaped leaves just below mid-height. The first young shoots are red-bronze, but those of later growth are usually green flushed with bronze. The four to 10 trumpet-shaped, cream-white flowers are about 6 inches long, the three lower petals are marked with deep yellow stripes, throat lightly spotted in brown-red. Yellow pollen.

New plants always grow from the daughter bulb, as the main bulb dies after flowering.
C. giganteum Makino 1913.
Himalayas: Simla, Nepal, Sikkim, Bhutan, upper Assam, northern Burma, south-eastern Tibet. This large, majestic lily has a strong, hollow stem 6-12 feet long, and is mostly found growing in very wet woodland glades. The broad, green, heart-shaped basal leaves form a rosette, and the others, scattered along the stem, are supported by long horizontal petioles. The scented, regularly funnel-shaped, 6-inch long flowers, also borne horizontally, are greenish-white on the outside and red-purple spotted with white on the inside. The large, reddish bulb requires shallow planting; as it dies after flowering it leaves small, offset bulbs on the base of the dying bulb. Should be planted in very damp, deep soil rich in plant nutrients. The planting hole, 24 x 24 x 20 inches in size, should first receive a layer of brushwood and be filled with-mould and topped with well-rotted manure. Winter protection with leaves, wooden boxes or wicker baskets. Three bulbs should be planted to ensure continuous yearly flowering. capsules reveal their fibrous teeth on opening, and release a rich harvest of light . Germinates after one year, flower mostly after seven years. (50)
