SUMMER AND FALL 1934 SEED AND BULB CATALOG 
PERENNIAL SCABIOSA—PINCUSHION FLOWER 
S. CAUCASICA (Isaac House’s New Hybrids). Hardy perennial; soft lavender 
blue and lilac shades, prized for cutting; 12 to 18 inches. Per pkt. 15c; two 
for 25c; 1/16 oz. 40c; % oz. 75c. 
SCABIOSA CAUCASIA. Avoid wet and heavy soil when planting these peren¬ 
nials, so useful for cutting purposes. Soil of a gritty nature suits them best, 
as excessive moisture at the roots is fatal. 
If you don’t grow this Scabiosa you are missing a mighty fine thing. Seed 
germinates readily. Plants bloom when only small seedlings. Very handsome flow¬ 
ers on long stems, blooming from early summer until frost time. A 2 or 3-year- 
old clump is a wonderous sight. 
THALICTRUM—MEADOW RUE Pkt. 
Th. Aquilegifolium. Large branched heads of feathery flowers in pink and 
white; beautiful cut foliage; fine border plant; 4-5 ft. Seeds, mixed_$ .15 
Th. Adinntifolium. Elegant foliage resembling that of the Maidenhair Fern. 
Admirable for bouquets, as the leaves retain their form for a long time 
when cut. Hardy perennial. Height 18 inches_ .15 
Th. Dipterocarpum. Tall growing perennial plants of great beauty, with 
loose sprays of clear mauve and primrose flowers; most graceful habit; 
thrives best in rather poor soil in the shade. Vs oz. 75c; 1/16 oz. 40c.25 
The seed of the latter is not ready until October-November. 
THERMOPSIS—PEA FAMILY (Family: Leguminosae) Pkt. 
Caroliniana. 3 to 4 ft. June-July. Long spikes of bright yellow flowers. 
Just the thing for planting among your Delphiniums to bring out the 
blue. This is a poor germinator, about 60%. 1/16 oz. 50c.$ .25 
EXCEPTIONS: In some cases we quote prices “plants sent by Parcel Post 
prepaid;” small seedlings and the German Iris may be sent by Parcel Post also, 
especially in the fall of the year, but in our judgment “EXPRESS SHIPMENTS” 
are much to be preferred and are strongly advised; you will save money in the end. 
SWEET ROCKET—HESPERIS 
The old-fashioned Dame’s Violet. A hardy perennial, easily raised from 
seed, blooms the following spring in May with the Iris and Aquilegia. Height, 
3 to 5 feet. Very fragrant. No garden should be without it. A lovely, graceful 
cut flower. If you sell cut flowers on Decoration Day, you will find the long, 
loose sprays a valuable acquisition. 
WHITE SWEET ROCKET. Per pkt. 15c; 2 pkts. 25c; % oz. 25c. 
PUDOR’S PINK SWEET ROCKET. After many years of selecting and re-select¬ 
ing, we have succeeded in establishing a fine orchid pink variety in place of 
the old purple variety. Seed, per pkt. 25c. 
TROLLIUS LEDEBOURI “GOLDEN QUEEN” 
GLOBE FLOWER 
Award of Merit, Royal Horticultural Society, London 
We offer again seed of this beautiful hardy perennial plant. It is a valuable 
garden plant and continues in bloom from June till October; in fact, we cut 
flowers outside as late as November. 
This variety is very vigorous; it grows quite three feet in height, but its chief 
value lies in the size of the flowers, which are four inches across; the rich golden 
color of the outer petals and the intense orange color of the smaller petals near 
the center of the flower intermix and blend beautifully with the yellow anthers. 
The plant is extremely floriferous and continues in flower for a long period; in 
fact, the constantcy with which it blooms in autumn as well as early summer is 
very remarkable. It comes practically true to type from seed. 
Most Trollius are rather uncertain to raise from seed when sown in the spring, 
but one of the great recommendations this introduction has is that the seed 
germinates freely when sown in the spring. We tested this point very fully by 
three successive sowings in March, April and May, when practically every seed 
germinated. Blooms same year if sown early. Seed, pkt. 25c; 1/16 oz. $1.00. 
EUROPEAN GLOBE FLOWER. Large, handsome globular flowers of a rich 
golden yellow or orange color. (See photo, inside cover.) Blooms last of May 
and early June. Growth rather slow, but when once established, a three-year-old 
clump is a magnificent sight. Only fresh, fall-sown seed will insure success. 
Seed bed exposed to frosts and snow might help. Spring sown seed, unless
