IRIS—continued 
*minuta—A tiny species of great rarity from Japan. Slender 
grassy foliage, with dainty flowers of a pleasing shade of 
yellow, marked with brown, on very short stems. 6 in. 
Summer. $1.00 and $1.25. 
*pumila azurea—lIn effect, a very much condensed Bearded 
(German) Iris. Large flowers of softest blue on 6 inch 
stems in early Spring. Sun. 50c and 75c. 
*pumila Sweetseri—A fine, clear yellow, fragrant and some- 
what taller than azurea. The two make an excellent com- 
bination. 50c and 75c. 
*ruthenica—A rare little species from the Balkans. Deep violet 
flowers, which have a sweet fragrance, on 8 inch stems 
during early Spring. Light shade. 75c and $1.00. 
unguicularis (stylosa) —The winter-blooming Iris. Large lav- 
ender blue flowers on 6 to 12 inch stems, sweetly scented, 
from mid- to late Winter. Requires a light, warm, well- 
drained soil containing lime. Excellent for cut fowers, cut 
in bud and opened indoors. Particularly suited to the border 
or large rock gardens in warm climates. However, it can 
be grown in cold sections in protected spots where it blooms 
in the late Fall or very early Spring. 75c, $1.00, and $1.50. 
unguicularis alba—A snowy-white variety with yellow mark- 
ings and darker green leaves. Distinctive and uncommon.

of blue, violet and gold, in early Summer. A moist, peaty 
soil in partial shade. 5 to 7 in. 50c and 75c. 
Northwest Native Species—These lovely kinds are listed in 
“Distinctive Hardy Plants for the Collector’s Garden’’ 
KNIPHOFIA 
KNIPHOFIA (TRITOMA)—(Red Hot Poker) —Stately border 
plants with clumps of long, narrow, basal leaves and naked, 
upright stems terminating in dense spikes of drooping, 
tubular blooms. The flowers range from white through yel- 
low and orange to scarlet. Some kinds are red in bud and 
yellow when open, creating a novel effect. Kniphofias grow 
very well in warm, dry climates and are satisfactory in 
colder areas if protected during the Winter. Plant in any 
ordinary, sunny soil which has good drainage. Spring de- 
livery only! 
Schimperi Hybrids (elegans multicolor) — Vivid and pastel 
shades which cover practically the whole range of colors in 
Kniphofias. A succession of blooms from mid-Summer to 
early Fall. 3 to 5 ft. Mixed shades only. 75c, $1.00, and 
$1.50. 
Sir C. K. Butler—A new introduction from England, with pale 
yellow and red flowers on 5 foot stalks. The first to bloom 
(early to mid-Summer) and one of the most pleasing color 
combinations. $1.00 and $1.50. 
Uvaria grandis (Pfitzeri) The last to bloom, late Summer 
to Fall, and often not so tall, 3 to 5 feet. Intense scarlet 
red and soft ycllow blooms on sturdy sta ks. 75c, $1.00, 
and $1.50. 
LINUM 
LINUM narbonnense Six Hills—Countless sapphire-blue flowers 
on 18 to 24 inch stems from early Summer to Fall. Flowers 
do not drop off each day, but last for several days. The 
grayish-green, needle-like foliage is interesting and dif- 
ferent. We consider this one of our best border perennials! 
$1.00 and $1.25. 
LITHOSPERMUM “*diffusum Grace Ward—An evergreen sub- 
shrub, wide-spreading mats of darkest green, covered with 
many large, sky-blue flowers during late Spring and early 
Summer and often again in early autumn. One of the most 
wonderful blues in the garden. It requires an acid soil, 
composed of good loam, some sand or silt, and plenty of 
leafmold or peat. 5 to 8 in. Full sun in cool sections but 
usually light shade is better. Shear heavily after blooming 
to keep compact and encourage flowering. Mulch lightly 
with boughs in Winter. We have discontinued the older, 
more straggly, and smaller-flowered Heavenly Blue for the 
new, more vigorous, and larger-flowered Grace Ward. Pots, 
75¢ and $1.00. 

LITHOSPERMUM DIFFUSUM GRACE WARD 
LOTUS *corniculatus fl.-pl. — A double-flowering form of 
Babies Slippers. Prostrate growth, with umbels of double 
yellow flowers, often tinged red. A hardy trailer for cover- 
ing dry banks and rockwork, flowering all Summer and 
autumn, in the poorest of soils. 50c to 75c. 
LUETKEA “pectinata—A native groundcover allied to Spirea. 
Prostrate and trailing undershrub, forming dense carpets 
of bright green, with 2 to 6 inch stems of fuzzy, creamy 
flowers in late Spring and early Summer. The emerald, finely 
dissected, evergreen foliage creates a distinctive effect. Re- 
quires a peaty, moist soil in light shade. From high eleva- 
tions in the Western mountains. Pots, 75c; field, $1.00. 
LYCHNIS *Viscaria splendens fl.-pl. — To quote Farrer, a 
“fierce’’ and ‘‘virulent’’” magenta. An ideal plant for those 
who like a bright display. The very double blooms on 12 to 
15 inch stems are carried in dense clusters over mats of 
narrow, evergreen leaves in late Spring to mid-Summer. 
Ordinary to poor soils in full sun. 50c, 75c, and $1.00.
