D1 Cole’s Acid Peat Humus Mixture 
A superior source for organic addition to any soil. 
Because all of this group of piants grow best in acid 
soil, under similar growing conditions, and have many 
characteristics in common, we are including them in a 
group. Most are members of the Rhododendron famti- 
ly, and, except where differences are noted, require 
similar care. Soil may be acidified by addition of alum- 
inum sulphate at 4 to Y2 pound per square yard, but 
it may be injurious to plants unless used with care. 
Cole’s acid peat humus can be used liberally with no 
chance of damage to plants. In any case, never use 
lime, bone meal, wood ashes or other alkaline material 
around these plants. 
A25 GOLDEN WARMINSTER BROOM 
(Cytisus praecox). The only truly hardy shrub that resembles the lovely, 
golden Genista or Easter Flower. A compact growing shrub that never 
becomes bare or leggy. at the bottom, even at its ultimate height of 5 feet. 
The unique, soft golden bloom completely covers the plant in the spring. 
Plants bloom at small size and grow well even in dry soil. They like acidity, 
however. Foliage is tiny and fascinating, while the branches stay bright 
green all winter. An excellent specimen which blends beautifully with ever- 
greens and Azaleas in the foundation. Prepaid, 3-year bushy, packed in 
peat, $1.75 each; 3 for $4.80.
