PRIMULA Juliae makes a neat spreading mat from which erect stems 2 in. 
high arise to carry most lovely claret colored primroses with a golden eye. 
Most dainty and does well in moist loam. 35 cts. each. 
PRIMROSES are delightful plants for the cool rock garden. See the lovely 
Blue, Double Lavender, and Double Pink varieties, page 64. 
PTEROCEPHALUS Parnassi forms dense, low masses of grayish foliage and 
produces, on 4-inch stems, many lilac-pink flowers much like those of Scabiosa. 
Grows in any soil, but is especially good in the dry, hot rock garden. Each 
25 cts; 3 for 60 cts. 
PULMONARIA angustifolia. This lovely cousin of the Mertensia has a tuft 
of rather large basal leaves and many 6 to 10 in. stems bearing heads of sky 
blue flowers in earliest spring. Plant in shade in a moist loam. 30 cts. each; 
3 for 75 cts. 
PYRETHRUM Tchihatchewii is a pretty tiny white carpeting daisy for the 
rock garden and takes heat and drouth well. 25 cts. each; 3 for 65 cts. 
ROSES. Rosa Spithamea is usually from 3 to 6 inches high and its creeping 
underground root makes little colonies. Its bright pink flowers borne so low 
are lovely. 50 cts. each. 
SAPONARIA Ocymoides splendens is a most useful plant. It makes a broad 
carpet even 2 to 3 feet across if planted on the level or covers a rocky spot or 
drapes a cement wall, no matter how hot, perfectly. The foliage is good and 
the show of pink flowers in spring very attractive. Good for rock garden or 
walls. 25 cts. each; $2.50 per doz. 
SAXXFRAGAS 
All of the many encrusted Saxifragas are unusually fine for the cool, lightly 
shaded nooks and pockets. The mossy ones for quite cool places; they need 
decidedly moist corners or the moraine. Mertensiana for clefts in cool rocks or 
covering a rock face where moisture is good. XJmbrosa for any cool place. 
Aizoon alba. A close tuft a few inches high. White flowers. 25 cts. each. 
Aizoon Lagaveana. Like last, creamy flowers. 35 cts. each. 
Aizoon rosea. Same as last, with rose flowers. 40 cts. each. 
See cut on page J/3 for character of Aizoon group. 
Apiculata. Spiny green rosettes and in very early spring, soft yellow flowers. 
35 cts. each. 
Ap iculata alba. White flowers. 35 cts. each. 
Cotyledon. A strong grower, with flowering mass as much as 2 feet high. 
75 cts. each. 
Hostii. Of same type as last. White flowers. 50 cts. each. 
Longifolia hybrida. Large rosettes with an 18 in. panicle of pure white. 
Each 30 cts.; 3 for 75 cts. 
Macnabiana. Very fine flat rosettes and tall spray of white. 35 cts. each. 
Decipiens. This delightful Mossy Saxifraga forms little tight cushion from 
which 3 inch stems arise bearing little white star-like flowers. Given a cool 
moist situation a succession of these little cushions will produce such a lovely 
colony as that pictured on page 41. 30 cts. each; 3 for 75 cts. 
Decipiens rosea is similar to Decipiens in habit and requirements but has 
flowers of glistening pink. Each 30 cts.; 3 for 75 cts. 
Mertensiana. This little Californian species is one of the daintiest of rock 
plants. The heart shaped leaves form a rosette an inch high from which arise 
slender 8 in. stems bearing tiny white flowers with red anthers. Forms de¬ 
lightful colonies on moist rock faces. The roots are little dry bulbs for fall 
planting. 25 cts. each; 3 for 60 cts.; $2 per doz.
