RARE PERENNIALS, ALPINE PLANTS

SAXIFRAGA IRVINGI 
SAXIFRAGA. ENCRUSTED SECTION—The 
majority are of very easy culture in any 
open, free soil, well-drained, with lime- 
stone chips added. They appreciate a 
little shade during the hottest part of 
the summer and moisture at the roots 
during the dry season. In gardens where 
it is difficult to give needed water, we 
advise planting in crevices facing either 
north or east. Flowering period June to 
Aug. 
*aizoon baldensis—The tiniest of the En- 
crusted Sax. Rivals the neat cushions 
of some of the kabschias. Creamy-white 
flowers on 3 inch stems. 50c each. 
*andrewsi—A hybrid between Sax, aizcon 
and Sax. geum, making a handsome plant 
with serrate, deep glossy leaves, edged 
with white. Sprays of white flowers, 
spotted pink, on 18 inch stems, July and 
Aug. Light shade and rich, moist soil. 
75¢ each. 
*cochlearis longifolia—A beautiful hybrid, 
with long, narrow foliage and white 
flowers in graceful plumes. 50c each. 
*cochlearis minor—Tiny domes of silvered 
rosettes. Graceful sprays of large white 
flowers on 4 inch reddish stems. 50c ea. 
*engleri—A hybrid, and one of the finest 
of the Encrusted section. Long, narrow 
leaves, heavily encrusted, in large ros- 
ettes. Plumes of white flowers. 50c ea. 
*lingulata alberti—Large rosettes of rather 
wide leaves, very silvery, and large 
plumes of white flowers. 50c each. 
*lingulata superba—A fine form of 5S. 
lingulata with long narrow leaves, grey- 
green, filmed with silver and which curl 
at edge and end. Arching sprays of pure 
white flowers. 50c each. 
*longifolia—Deservedly called “Queen of 
the Saxifrage’”. Huge rosettes of silvery 
grey, which do not produce offsets. Well 
grown plants will often measure from 10 
to 14 inches across, with flower spikes 
measuring 3 feet. We have the true plant 
from the Pyrenees. $1.50 each. 
*longifolia Tumbling Waters — A truly 
magnificent form, which makes offsets. 
3-4 ft. spikes of solid white. $1.50 each. 
*longifolia Borschs Variety — Seedling of 
Tumbling Waters, but with very small 
and compact rosettes, heavily encrusted. 
$1.00 each. 
*paradoxa— A very choice and rare hy- 
brid. Long and narrow foliage, of a 
sombre grey edged with conspicuous sil- 
ver beading. $1.00 each. 
*pyramidalis—A form of S. cotyledon, with 
large, broad-leaved rosettes and im- 
mense panicles of white flowers, speck- 
led with crimson. 35c and 50c each. 
SAXIFRAGA. MISCELLANY OF SPECIES. 
*aspera—A very rare and distinct species, 
making dense and rambling mats of 
rough and mossy shoots, like those of 
some very narrow-leaved and condensed 
Phlox subulata, with bristly edges and a 
bristly end to all the stiff huddled little 
needle-like leaves of glossy green, taking 
a dusted look from their bristliness, and 
bearing gem-buds embedded in their 
wandering shoots. The frail stems as- 
cend weakly some 4 inches, with rather 
large pale butter-colored flowers, speck- 
led with orange at base. Easy in any 
open place, in stony well-drained soil. 
75c and $1.00 each.
