HILLSDALE LANDSCAPE Co. 
HARDY HERBACEOUS OR PERENNIAL PLANTS 
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.
