Family

Liliaceae

Botanical Name

GALTONIA princeps

Plant Common Name

Berg Lily, Drakensberg Lily, Summer Hyacinth

General Description

The South African berg lily bears summer spikes of lightly fragrant, drooping white flowers. A seasonal summer bulb from the Drakensberg Mountains of South Africa, it is quite rare in cultivation but very beautiful.

The fleshy, light to gray-green leaves of this Galtonia are strap- to lance-shaped and may be held erect or gracefully arch. In late summer, depending on mildness of climate, leafless stalks rise and bear light green flower buds that open to show pendent, white flowers marked with pale green bands. The flowers open from the bottom of the spike to the top.

Grow summer hyacinth in full to partial sun and fertile, well-drained soil that is moist in spring and summer but drier in winter. In areas with mild winters, summer hyacinth creates impressive clumps and floral displays. Where winters are colder, it must be better protected and kept drier in the cold months. The bulbs may also be dug in fall and overwintered indoors in a cool, dry place, like gladioulus bulbs. Container grown specimens may also be brought indoors.
