In the garden

Cardiocrinum giganteum comes from the Himalayas to China and Myanmar and is valued for its tall, summer-flowering habit. Expect its flowering season in the UK to be July and August; the plant reaches about 1.8 m and is appreciated where height and scent are wanted. In British terms it is H6, very hardy, and corresponds to USDA zones 6–9. Give it moist but well-drained soil: it tolerates sandy, loamy or clay textures and a wide pH range from acidic to alkaline. Plants will succeed in partial shade or full sun provided the site is sheltered from strong winds; the listed aspects (north, east, south, west) are all acceptable when exposure is sheltered. Keep soil moisture even rather than allowing the root area to dry out completely. Use Cardiocrinum giganteum as a vertical focal in mixed borders or where you need tall stems for cutting; its summer blooms supply fragrant material for vases. Locate it where the tall flower stems can be supported by surrounding planting or discreet stakes to protect the flowers while they are at their peak.
