tufts at which the wind tugs hard to draw them from 

 the ground will be lively in spring or early sum- 

 mer with small but numerous flowers." 



The other species, the Heath-like Hudsonia, Hud- 

 sonia ericoides, is less downy than Hudsonia tomentosa. 

 The leaves are slender and awl-shaped ; are a little 

 longer, spread a little more, and are covered with 

 longer and thinner hairs than those of the Downy 

 Hudsonia. The old leaves are persistent and the stem 

 often looks dry. It usually blooms the earlier of the 

 two. The flowers of both species are very similar in 

 size and color and equally fleeting. Both plants are 

 difficult to establish in gardens, but once established 

 they grow, spread, and make excellent, dwarf, rock 

 garden shrubs ; they can also be used as a carpet 

 about taller plants.
