20c each, 3 for 50c, except where otherwise priced. 
By this term is meant such plants as may be allowed to remain permanently in 
the open ground, whose foliage dies down to or near the ground each autumn, coming 
forth again with renewed vigcr the following spring, giving a continuation of bloom 
from early spring until frost. All our plants are field grown and are many times larger 
than seed bed plants. 
We are constantly searching for and adding new and rare varieties of merit to our 
extensive collection.
