Q. Will you please favor me with a list of hardy plants, tall, 

 medium and dwarf for edging a rhododendron planting ? The edge 

 has enough sun for sun loving plants. 



A. For Rhododendrons edging use Abelia, White Day Lilies, 

 White and Blue Carpathian Harebells, White and Blue Dwarf 

 Delphinium Chinensis, White Desmodium, all the Violas, Iberis, 

 Forget-me-nots, and White Dianthus Sedums-Andromedas 

 C Weeping^ Bleeding Hearts CDwarf Fromosa^ Hardy Primroses, 

 Japanese Lychnis, the purest White "Grandiflora Alba" Merteusia 

 CBlue Bells^ Lupines Polyphyllus — Blue, White and Pink Moer- 

 heimi. 



I believe a two foot border of Andromeda Cweeping^ with 

 ever-blooming Forget-me-nots CPalustris^ White Dianthea 

 CSnowball^ hardy golden Primroses and Violas filling in the bare 

 places would be very sweet, or the dwarf Delphinium Chinensis, 

 Japanese Iris, Forget-me-nots and Violas. Or a waved line of 

 dwarf Bleeding Hearts CFormosa^ the bare places filled with 

 Iberis. These are all hardy plants, soft, fine colors and excellent 

 for bordering and edging.

Q. Please suggest what you would recommend as a good grace- 

 ful shrub not too dwarf to plant against a wall. 



A. Desmodium-pendula Lespedeza. This shrub is extremely 

 graceful. It will grow to five feet in good soil, but as it is so pen- 

 dulous and showering, it may be used to perfection as a "wall" 

 shrub. The drooping flower pendants are a deep fine purple and 

 with a spot of scarlet at the base of each.
