RARE PERENNIALS, ALPINE PLANTS 
15 
DICTAMNUS (Gas-Plant) albus —A very sat¬ 
isfactory plant, both on account of its 
showy flowers and fragrant, rich and 
durable foliage. Grows about 2 feet high 
and during the summer months produces 
its odd-shaped flowers of white. Should 
be planted in a permanent place, as it 
improves with age. Full sun in a heavy 
soil. 3 yr. old plants, 50c each. 
a. ruber —(Purple Gas-Plant) Spikes of 
rosy pink flowers with deeper veins dur¬ 
ing June and July. 50c each. 
DODECATHEON — (Shooting - Star) Also 
called Wild Cyclamens, the flowers re¬ 
sembling those of the hardy Cyclamen. 
They are among the finest of our far 
western early flowering alpines. They 
form close rosettes of rather broad 
leaves, from which naked stems arise 
with umbles of Cyclamen-like flowers, 
from March to May. We recommend 
planting them from early March to July, 
as they do not split into small divisions 
during that time, in a light moist soil, 
which has plenty of humus. From 1 to 2 
inches deep, with partial shade.

35c each.

Columbia River Gorge form, with large

alpines. Not difficult if planted in a 
gritty, stony soil, with some sand and 
leaf mold or peat, and perfect drainage.

with small pink flowers in early spring. 
50c each. 
DOUGLASIA *vitaliana — Also listed as

European species of Douglasia. Forms 
rosettes of grey-green short leaves.

petala. The seed heads of all these Dryas 
are very ornamental. 35c each.
