California Bulbs, Rock Plants, Unusual Perennials

IRISES. Most Irises are too large for the rock garden, but Iris Pumila , which 
is very dwarf like the German Iris, fits perfectly, while some of the tiny Iris 
species are as good. 
IRIS Pumila has the characteristic foliage of the German Iris, but is only 
about 4 inches high. They are among the earliest of spring flowers and in 
California flower in winter. The little clumps are very charming. I offer 
the following varieties: 
Aurea maculata. Light yellow, mottled brown. 
Atroviolacea is deep blue-purple. 
Bride. Pure white. 
Prairie Gem. Soft yellow. 
Royal Purple is self descriptive. 
Ei.her of these at 30 cts. each. Collection of 10 plants, 2 each of five varie¬ 
ties, for $2. 
I. cristata has foliage but 2 to 3 inches high, with very dainty blue flowers, 
crested orange. Fine for moist corner. 25 cts. each. 
CALIFORNIAN AND OTHER PACIFIC COAST IRISES are splendid for the 
rock garden, their long grassy leaves making striking clumps while the flowers 
are exceptionally pretty. Some of them are too large for the small rock garden 
and I give heights as a guide. These are splendid irises for a woodland situa¬ 
tion. I. Tenax likes a moist situation while all the others require a well drained 
soil rich in leaf mold with moderate moisture. Perfectly hardy but a little 
difficult to establish. 
X Bracteata. 12 in. Evergreen foliage and golden yellow flowers. 
X Californica Varied. 8 in. Varied in many rich shades, no two alike, in blues, 
yellows, bronzes, violets. 
Californica Blue. 6 in. Rather dwarf with flowers of deep blue. 
I. chrysophylla has sparse foliage 6 to 8 inches high with creamy flowers 
tinted yellow and purple. 25 cts. each. 
X Douglasiana. 12 in. A bold species with broad evergreen grassy foliage 
and creamy flowers. Of very easy culture. 
Macrosiphon. Dwarf, slender grassy leaves and deep blue flowers. 
X Purdyii has glossy, deep green, grassy foliage 6 to 8 inches high with large, 
handsome, creamy flowers tinted yellow and purple veined. 25 cts. each. 
X Tenax. One of the most dwarf of all Irises, 3 inches high, with reddish- 
purple flowers. Quite striking. Likes quite moist soil. 25 cts. each. 
Watsoniana. 12 in. Broad soft green leaves and light blue flowers. 
Prices of above: 25 cts. each; 3 for 60 cts.; $2 per doz. 
X. Seeds of species prefixed with an “X” at 25 cts. per pkt. 
LAMIUM maculatum. Often we professional gardeners overlook a good thing. 
When I planted Lamium in a new rock garden this spring it was simply as a 
filler, but no plant has been more admired and no plant better fills a pocket 
than this one does. The greyish foliage is beautifully variegated white with 
purple mottling and the very pretty rosy-purple flowers appear over a long 
season. Curb it when it overgrows, as it may. Either sun or shade. 25 cts. each. 
LAVENDER Dwarf Munstead. Is invaluable for the rock garden. It is an 
evergreen shrub and makes a round-headed little tree a foot high. I had never 
thought of this fine plant as of value in flowering, but this spring I came to 
realize that its masses of tiny bluish-lavender flowers are really fine. Each 
50 cts. 
LEWISIAS are the New World’s best contribution to the rock garden and I 
doubt if the world has produced a rock plant more attractive than Lewisia 
Tweedi. That lovely species with its picture and many others in a separate 
section of this catalog. See pages 26 to 29. 
LINARIA aquitriloba is one of the lowest of plants. It makes solid mats less 
than one-half inch high of pretty rounded leaves and these are thickly studded 
with blue flowers. Fine for colonies in rocks or between stepping stones. Each 
25 cts.; 3 for 60 cts. 
LINARIA alpina is low and dense with slender 6 inch flower stems, the 
flowers deep blue with an orange spot. It flowers all summer and is very 
pretty. 30 cts. each; 3 for 75 cts.
