Scientific Name (Genus/Species): Asparagus schoberioides
Family: (Asparagaceae)
(P) to 3′. Siberian Asparagus. Far East Asia. This delicately textured perennial, though edible, is largely grown for its ornamental value in a garden setting. Arching stems of fine needle-like light green foliage provide an airy, ethereal presence. Tiny white flowers in summer are followed by bright red fruit in fall when the foliage turns golden yellow. Asparagus plants are typically dioecious and therefore both male and female plants are required for fruit production. Our plant was purchased from Seneca Hill Nurseries in 2007. It is planted in the Grass Garden where it has been producing fruit happily for at least the past 10 years. Just lovely. Sun. 2B, 3 & T3
