tained the glorious dark color of V. 
subsessilis. Bushy habit, about 2 ft. 
high. 35c each. 
VIOLA —The Viola is not as well known in 
America as it should be. Very few other 
plants have as long a flowering period. 
They succeed best in a deep, well-en¬ 
riched, well-drained soil, but with plenty 
of water during the hot summer. They 
seem to prefer a light shade during the 
hottest part of mid-summer days. Do not 
allow to go to seed, and in Sept, cut 
back all straggling growth, to allow 
plants to make new tufts. This applies 
to the cornuta type in particular. The 
following are varieties and forms of 
Viola cornuta and bedding Violas. The 
specie Violas, both native and foreign, 
are listed separately.
