Liatris aspera-sphaeroidea X. L. spicata alba. A very lovely hy- 
brid that originated by chance at Gladwyne. It has the vigor- 
ous growth and silvery transparent bracts on its buds of L. 
aspera-sphaeroidea, which is probably the handsomest of 
all Liatris. The pale lavender pink flowers are produced in 
great quantity on branching stems. A beautiful plant for 
the large rock garden or cutting garden late in the season.
