A hardy perennial plant, native of the Altai mountains, ~ 
from whence seeds were sent to the Horticultural Society, 
in 1823, by Dr. Fischer. Our drawing was made at the 
Chiswick garden in May last. The flowers are of a very 
lively colour, and endure, in succession, through all the 
summer months. 
We find no material difference between the cultivated 
plant and spontaneous specimens. Willdenow, however, 
observed, the flowers of plants, in the Berlin garden, in- 
crease in size, till they became half as large again as in a 
state of nature.
