DWARF TREES AND SHRUBS 



freely, but some of these dwarf forms are rarely or never seen in bloom 

 as, for instance, Catalpa bignonioides nana and Viburnum Opulus 

 nana. 



In gardens with a soil free from lime or other calcareous matter, the 

 members of the heath family fill a conspicuous place among naturally 

 dwarf evergreens. It is not necessary here to mention them all. They 

 are dealt with in the body of the work, and many of them may be 

 found by consulting the following genera: Erica, Calluna, Kalmia, 

 Gaultheria, Rhododendron, Phyllodoce, Dabazcia, Pernettya, Cassandra, 

 Ledum, Bruckenthalia, Leucothoe, Andromeda, Vaccinium, etc. For other 

 species of naturally dwarf stature the reader is referred to the following 

 genera : Astragalus, Berberis, Corema, Cotoneaster, Cytisus, Daphne, 

 Empetrum, Ephedra, Erinacea, Euonymtis, Helianthemum, Hypericum, 

 Pachysandra, Pachystima, Polygala, Potentilla, Ruscus, Salix, Sarcococca, 

 Veronica, Vinca, Yucca.
