Easy · Beginner friendlyAbout Himalayan Sweet Box
Himalayan Sweet Box is a suckering evergreen groundcover shrub reaching 2-4 feet tall with narrow glossy dark green leaves and intensely fragrant tiny white winter flowers. More vigorous than S. confusa and spreading by underground runners, it creates a dense evergreen mass in shade. The variety humilis stays low at 1-2 feet, ideal as a fragrant evergreen groundcover beneath trees and shrubs in cool shaded US gardens.

History
Sarcococca hookeriana is native to the eastern Himalayas (Nepal, Bhutan, northeastern India, southern Tibet) and western China. French botanist Henri Ernest Baillon formally described the species in 1871, honoring Sir Joseph Dalton Hooker, the great Victorian botanist and director of Kew who had explored the Sikkim Himalayas extensively in 1848-51. Three varieties are recognized: var. hookeriana (the type, upright to 1.5 m), var. humilis (low-growing, suckering groundcover to 40 cm, often sold separately as S. humilis), and var. digyna (taller with narrower leaves, 'Purple Stem' is a notable cultivar with reddish new stems).
All share the genus hallmark: tiny but intensely fragrant cream-white flower clusters in winter, emitting a sweet jasmine-honey-vanilla scent that perfumes shade gardens in the dark months. Glossy black berries (or red in var. digyna) follow the flowers. Shade, drought, deer resistance, and dry root conditions are all tolerated.
Hardy to zone 6. Native to the Himalayas from Afghanistan through Sichuan, collected and introduced to Western horticulture by Joseph Hooker of Kew Gardens in the 19th century. The dwarf 'Winter Gem' is a signature plant of modern Pacific Northwest shade gardens.
