Armeria Six Hills 
; ARNEBIA. Prophet Flower. (Boraginaceae, Borage Family) 
Arnebia echioides. Low clumps of dark green leaves that produce long procumbent 
stems bearing fascinating large bright yellow funnelform flowers with large brown 
spots. The spots fade (to hearld the comming of the Prophet Mohammed)’ with 
age, leaving a pure yellow blossom. It is easy to grow in a well drained garden 
soil in full sun. This gem from Armenia blooms in April and May and sometimes 
through the summer. (pH 6-8) 
ARRHENATHERUM. Oat Grass. (Gramineae, Grass Family) 
Arrhenatherum tuberosum variegatum. (A form of A. elatius) Grasses are usually con- 
sidered weeds by rock gardeners, but this one is a welcomed addition to any good 
plant collection. A very attractive clump of long striped green and white leaves 
about 10 inches high. A pleasing contrast to the green and gray leaves and bright 
flowers of the other plants. Easy to grow in full sun or light shade in any ordinary 
soil. (pH 6-8) 
GARDEN SOIL AND GRITTY LIME SOIL 
The plants described as wanting ordinary garden soil will thrive in the 
same ground that produces good vegetables or good annual or perennial 
flowers. Our potting soil in which we grow most of our plants consists of the 
following: ten parts good top soil, one part sharp sand, one part stone chips, 
1% part dry cow manure, two parts leafmold or peat moss, ™% part chipped 
oyster or clam shells or limestone chips. If your top soil is very acid add % 
part pulverized limestone. If your soil is naturally alkaline leave out the chipped 
shells. 
For the gritty lime soil mixture we use three parts top soil, one part leaf- 
mold or peat moss, one part sharp sand, one part stone chips, % part limestone 
chips or shell chips and % part dry cow manure, This should be thoroughly 
mixed before planting, 
ARTEMISIA. Wormwood. (Compositae, Daisy Family) 
Artemisia frigida Silver Dome. (Fringed Wormwood) A perfect rounded dome of 
sheer silver foam, from 8 to 10 inches high and about 15 inches in diameter. An 
irresistibale plant that is loved and wanted by everyone that sees it. The flowers 
are small yellow discs that should be cut off before they spoil the symmetry of the 
plant, Some time the plants that are grown in shade or too rich a soil flop open 
in the center. If this happens they should be cut back severely in July. They will 
quickly fill out to a fluffy mound again. Easy to grow in full sun and any ordinary 
soil, but prefer a dry sandy soil. (pH 6-8)
