EVERGREEN LEWISIA, Rock Rose 
In all the world there is not a more interesting group of 
rock plants and they are worth any effort to grow them well. 
They vary widely, each species distinct and interesting and 
desirable. All have low rosettes of fleshy leaves, but in each 
species they are intriguingly different. Plants have a few to 
many stems, 6 to 12 inches high, each bearing from five to 
numerous flowers. Very hardy without protection even to 
Montreal. 
Culture: In the wild they grow into rocky slopes or cliffs 
with roots almost horizontal and kept cool by the rocks. You 
must simulate such conditions to grow them in the open. 
Otherwise plant them in pots which you ean tilt at 45 degree 
angle. The ideal soil is a silty loam rich in fine acid humus. 
Loam, sand and peat moss equal parts would approach this. 
Give liberal moisture Sept. 1 to May 1, partly dry off to rest 
plants in summer. Situation should be light shade, in damp 
regions full sun. Pl. fall to spring, in East spring. 
**Finchii. This species varies considerably and I have now 
selected its very finest strain. In this the foliage is deep 
emerald green with leaves overlapping closely to make a 
solid rosette often 8 in. across, Its few to 20 scapes each 
bear 5 to 40 flowers and plants have been seen with 600 
flowers. The buds are bright orange. Open, the flowers 
are soft pink with rose strips and the petals margined 
orange. A fine specimen, is a wonderful sight. Each 40 
cts.; 3 for $1.00. 
**Hecknerii is perhaps the best marked of the group. First, 
the broad dark green leaves, red beneath, are margined 
with slender spines each tipped brown. These tiny spines 
give the effect of a silky fringe. Then the fine large flow- 
ers are a solid rose pink, without stripe. The bracts and 
sepals are margined like the leaves with even finer spines. 
A plant bears from a few to many scapes each having a 
few to 12 flowers. Very distinct and desirable. Each 40 
cts.; 3 for $1.00. 
**Hecknerii “Elegans”. A most outstanding new variety 
(1937) with strong rosettes as much as 8 in. across. The 
very dark green leaves have charmingly undulated mar- 
gins and these are lined with slender spines as in Heck- 
nerii. The scapes bear 14 to 40 flowers each, of large 
size and a lovely medium rose without stripe. A decided 
acquisition. Strong plants, 50 cts. each; 3 for $1.25. 
**Howellii. Leaves beautifully crisped and crinkled on mar- 
gin, are deep green much tinted red. Its many scapes 
carry 3 to 10 flowers of pink, margined white and witha 
broad purplish violet central band. 30 cts. each; 3 for 
75 cts. 
PLEASE NOTE: If you authorize shipment express collect 
or remit 25 cts. per plant extra to pay postage, I will send 
extra choice plants of the above kinds at catalog price. 
Tweedyii. I very much regret that I will be unable to supply 
this lovely species for the duration. 

Chihuahua, Mexico: “The plant on my order came in 
splendid condition, much better than any I have received 
from the East. Thank you very much for the extra ones. I 
am sorry that I did not discover you earlier.”

DECIDUOUS LEWISIA, Bitterroot 
Lovely and distinctive West American plants and a real 
acquisition for the alpine and rock garden. All grow in 
early spring, flowering in April to May. The leaves ripen 
as the flowers fade and the roots lie dormant through 
the summer. Fine in pots. 
Culture of Deciduous Lewisias. All grow where it is decid- 
edly moist during the growing season or where roots may 
reach into moist rock crevices. Drainage should be per- 
fect; soil, best a light loam; situation, full sun; mois- 
ture, liberal during growing season but may be dried off 
after flowering. The scree is ideal for them. Cover tip 
of root 1 in. Shipped fall only, but you may hold the dor- 
mant roots for spring planting if desired.

**Brachycalyx. Without question, this lovely species is one 
of the most notable additions in many years to the really 
fine in rock garden plants. Exceptionally hardy and easily 
grown, it has brought the highest praise from all who 
have seen it. It has many leaved rosettes of laceolate 
leaves which cling closely to the earth. The stemless 
flowers come in such profusion as to completely hide the 
plant and are 1% to 2 inches across, white, tinted pink. 
See beautiful picture opposite. 40 cts. each; 3 for $1.00. 
**Oppositifolia has linear leaves, broadened at tip, and few 
in number. Stems 6 to 12 inches high arise erectly and 
bear a number of beautiful white flowers an inch across. 
A most beautiful little species. 15 cts. each; 3 for 40 cts.; 
$1.50 per doz. 
**Rediviva is Bitter Root. Many slender, round leaves, an 
inch or two long, crown the root to make a dense rosette. 
Through these leaves arise many stems, each bearing a 
single flower. The flowers are white to pink, an inch 
and a half across and have the satiny texture of the 
Cactus flower. An admirable species and most effective 
in little raised pockets in the rock garden. See picture, 
page 35. 25 cts. each; 3 for 60 cts.; $2 per doz. 
The above prices are postpaid to your door.

Lewisia are worth any etfort to grow them well but are not for amateurs. Page 19
