Obs. Several other species are sometimes seen in gardens, among which are D. Thapsi,with mullein- 

 like lea vea all radical and flat on the ground; D. leucophaa, with very large, dense, leafy racemes of 

 dusky white fls. Numerous hybrids also occur in gardens, produced between the above species which are 

 often difficult to distinguish.
