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 vigor 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.
