Hardy 
Herbaceous or 
Perennial Plants 
These plants may remain permanently 
in the open ground. The foliage dies 
down each autumn and appears again 
the following spring. All our plants are 
field grown and are many times larger 
than seed-bed plants. We are constantly 
adding new and rare varieties to our 
extensive collection.
