a very interesting plant, its flowers changing colour 
as they approach maturity, being almost white at 
first, changing to yellow and turning to a rosy 
purple before they fade. AU except Allionii are 
best propagated from cuttings, which 'root without 
difficulty during early Autumn. C. Allionii may be 
depended upon to come true from seed provided 
a good stock is used, and of course the varieties 
of C. Cheirii, the ordinary Wallflower, are also raised 
from seed. 
Chelone. — There are three or four species of 
Chelone which make quite useful subjects for group- 
ing in the herbaceous border where their flower 
heads will produce a show of rosy, purplish, or white 
flowers for two or three months. The stems grow 
erect and are furnished with ample foliage, the 
blossoms being closely packed in a crown, the in- 
dividual flowers somewhat resembling a half-opened 
Antirrhinum, the popular name of * Turtle's Head ' 
being not inapt. 
C. obliqua is of a pleasing porcelain pink, and 
there is a white variety of this species, whilst C. 
Lyoni is of a rosy purple.
