EATHER-PROOF” HARDY PERENNIALS 
WEATHER PROOF PERENNIALS — Rocknoll is located 22 miles north of the Ohio River in South- 
western Ohio. We have severe cold winters often without a protecting snow blanket and hot dry summers. 
Temperatures range from 20 degrees below zero F. in winter to 100 degrees in the shade in summer. We 
have periods of heavy rainfall and periods of drought just the same as you do. 
Our soil while very fertile and productive is only good farm land used for growing corn before we took 
it over. We do not have deep black celery soil or sandy old lake bottoms to force fast growth on plants 
that often fail to hold up when moved to your garden soils.

ROCKNOLL GIANT 
LONG SPURRED COLUMBINE 
This is a superb strain of giant flowered varieties 
in every imaginable shade and color blend to be 
found in columbine. The stems are all long and 
graceful and the flowers abundantly produced on 
the stems. We find the best columbines to trans- 
plant are one year old field grown plants, as these 
still have the vigor of their first full flowering 
period just ahead of them.
