26 Raven Rock Nursery PERENNIALS 
Perennials 
During the past few years, perennials or hardy flowers have gained a tre¬ 
mendous popularity. People have come to realize that by the proper selec¬ 
tion of fine perennials, their gardens may have an abundance of beautiful 
flowers for the entire season. 
There is another trend today, as you are probably aware, towards rock gar¬ 
dening. The idea is to utilize an otherwise useless bank or corner and to 
create, with the use of rocks, low growing plants and evergreens, an inter¬ 
esting and delightful rock garden. It is surprising how attractive even a 
limited space can be made with the little gems of flowers offered in the fol¬ 
lowing pages. You are cordially invited to visit our nurseries and see our 
rock gardens where we have endeavored to illustrate to our customers the 
proper use of these plants. We are always glad to render any possible assist¬ 
ance in the selection of any plants you desire. 
Our aim is to produce only the best varieties of the most popular choice 
perennials. Although not listed in this catalog, our botanical friends visit¬ 
ing our nurseries will always find some rare plants or new horticultural 
introductions on trial in our show grounds. 
The quality and size of our plants at Raven Rock Nurseries reflects itself in 
the ever increasing number of our satisfied customers, many of whom make 
it a habit and find it a great joy and pleasure to visit our nurseries at regular 
intervals. The prices quoted in this catalog are for strong field grown clumps. 
In addition, we are able to furnish certain varieties in V/f inch pots at 10c. 
each, $1.00 per dozen. At certain seasons of the year we will also have some 
varieties which we can offer in smaller sizes than our regular field grown 
plants and which will be priced according to their respective sizes.
