DREER'S COLLECTIONS OF HARDY PERENNIAL PLANTS 



The list of Hardy Perennial Plants which we offer is admitted to be one of the most complete and up-to-date collections in the country, 

 and we are continually adding all the new, rare and desirable sorts. 



While we are not in the landscape business and cannot undertake the preparation of plans for planting or 

 laying out of grounds we have had prepared by a competent landscape architect a series of Plans of Hardy Borders with a 

 list of suitable plants for positions either in sun or shade. Also a list of plants suitable for Rock Gardens with general advice on the 

 construction and care of same. We will be pleased to send this leaflet free on application. We also offer customers who are not ac- 

 quainted with the different sorts the following collections, all in good, strong roots, which when once planted will, with little care, keep 

 the garden and Rock Garden gay with flowers from the time frost leaves the ground until late in autumn. These collections are made 

 up of species and varieties strictly of our selection, and we are unable to submit list of contents, as the assortment 

 varies at different periods during the planting season.
