Mr. Douglas informs us that this beautiful species is an 
inhabitant only of woodless, scorched grounds, where, from 
its compact habit, it forms thick carpets of purplish blue, 
giving a relief to the eye from the micaceous sand in which 
it delights to grow. it occupies the same range of country 
as L. leucophyllus, and is equally common with that species. 
The spontaneous plant is white, with long hairs, and is 
a true perennial; but the Garden plant, which is much 
less hairy, can scarcely be considered more than biennial : 
from the profusion of the flowers, the plant soon becomes 
exhausted ; and this, together with its impatience of mois- 
ture, and the humidity of our climate, is apt to destroy it.
