42 GARDEN GUIDE 



Vinca minor is also useful; it is cheaper, but the leaves are not so large. 

 The common Juniper (Juniperus communis adpressa) is also valuable; 

 it requires sun. All of these three plants are evergreen. Several ex- 

 cellent low deciduous shrubs for ground cover in the sunshine are the 

 aromatic dwarf Sumach (Rhus aromatica), Yellow Root (Xanthorrhiza 

 apiifolia), which spreads rapidly by underground stems; it does not 

 thrive in limestone soils. Sweet Fern (Myrica asplenifolia) will 

 thrive on the driest, sunniest slopes; Memorial Rose (Rosa Wichur- 

 aiana) is excellent, bearing numerous white flowers in late June or 

 July; English Ivy and Euonymus radicans var. vegeta may also be 

 used. The English Ivy, though very beautiful, is often rather tender; 

 it enjoys a moist soil and shade in Winter.
