EVERGREEN LEWISIA, Rock Rose 
In all the world there is not a more inter- 
esting 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 intri- 
guingly 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 can 
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. 

Lewisia Howellii 
**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. 
DECIDUOUS LEWISIA, Bitterroot 
Lovely and distinctive West American plants and a real 
acquisiation 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

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. 
**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 com- 
pletely hide the plant and are 1% to 2 inches across, 
white, tinted pink. See beautiful picture opposite. 
40 cts. each; 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. 
1948 supply uncertain. Name a substitute if you order. 
** 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 with a 
broad purplish violet central band. 30 cts. each; 3 for 
75 cts. 
**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. 
Tweedyii. I very much regret that I will be unable to srpply 
this lovely species for the duration. é ae : 
ee **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.
