About
Sternbergia lutea, the winter daffodil, autumn daffodil, fall daffodil, lily-of-the-field, or yellow autumn crocus, is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, in the Narcisseae tribe, which is used as an ornamental plant. It has yellow flowers which appear in autumn.
The Latin specific epithet lutea means "yellow".
How to grow it
Sternbergia lutea is hardy to USDA hardiness zones 7–9 (−18 to −1 °C) depending on the degree of protection given. It can be grown outside in the British Isles in well-drained soil; a warm dry period in summer is required for good flowering. Alkaline soils are recommended. Bulbs are usually planted while dormant (i.e. in late summer or early autumn), but can be lifted and divided before the leaves die down in late spring.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.
