PLANTS TO EDGE BEDS OF LARGE 



SHRUBS 



A correspondent of the Arboretum 

 writes: "Can you recommend several 

 shrubs suitable for edge planting 

 before taller shrubs? I have used 

 Xanthorrhiza considerably, but it is 

 almost the only shrub that I find low 

 enough for that purpose. I want to 

 bring some Cornels down to the edge 

 of a drive and I also want to plant in 

 front of Privets and Thorns." There 

 are not many shrubs with deciduous 

 leaves which can be successfully used 

 for this purpose. The best which has 

 been tried in the Arboretum is the 

 Fragrant Sumach (Rhus canadensis, 

 or as it was formerly called Rhus aro- 

 matlca). This widely distributed 

 North American shrub rarely grows 

 more than five feet tall, and when 

 planted in good soil is often broader 

 than tall with lower branches spread- 

 ing flat on the ground, and upper 

 branches erect spreading or drooping. 

 In early spring before the leaves ap- 

 pear the branches are covered with 

 clusters of small bright yellow flowers 

 which in June are followed by dull red 

 fruits which are pretty much hidden 

 by the small compound leaves. 



Among the small shrubs in the Ar- 

 boretum few are more brilliant at this 

 season of the year for the leaves turn 

 gradually to bright scarlet and orange. 

 The Rhus has been largely planted 

 along some of the drives and this 

 week it is a conspicuous feature of the 

 Arboretum. The Xanthorrhiza has 

 also been largely and successfully used 

 here. It makes a neat border plant, 

 and it is also well suited to grow un- 

 der tall shrubs or trees. The Xanthor- 

 rhiza spreads rapidly by underground 



stems which do not grow more than 

 from twelve to eighteen inches high; 

 the small purple flowers which are ar- 

 ranged in drooping clusters, appear as 

 the leaves unfold; these are pinnate, 

 of a cheerful green color and in the 

 autumn turn pale yellow. 



Some of the North American Roses 

 might be used to edge beds or larger 

 shrubs although most of them are too 

 upright in habit to be really useful for 

 this purpose. There is a dwarf from 

 the Choke-berry (Aronia nigra) in the 

 Arboretum collection which might be 

 used to advantage for this purpose. 

 Unfortunately, however, it probably 

 cannot be found in commercial nurs- 

 eries. This Is true, too, of the dwarf 



Quince of Japan (Chaenomeles japon- 

 ica, sometimes called Pyrus or Cydonis 

 Maulel in European nurseries). This 

 Is a shrub with spreading branches 

 which do not rise more than two feet 

 above the ground. The flowers vary- 

 on different plants from crimson to 

 pink and to white, and are followed by 

 small yellow, fragrant quince-like fruit. 

 These handsome little shrubs, like the 

 larger Quinces and many related 

 plants, attract the San Jose scale, 

 which needs careful watching and fre- 

 quent spraying. All the Snowberries 

 ( Symphoricarpus) including the red- 

 fruited S. vulgaris can be used in front 

 of larger growing shrubs; and the trail- 

 ing stems of one of the American Burn- 

 ing Bushes (Evonymus obovatus) 

 make a good border when taller plants 

 protect them from the direct rays of 

 the sun.
