Primula vulgaris coerulea. A very deep, dark, pure blue variety of this fine plant. This 
is the plant sometimes listed as Queen of Heaven, however most of them are grown 
from seed and the color does vary to light blue or purple. It thrives in a good rich 
garden loam well fortified with humus and manure, in shade or half shade. (pH 5-7)

Primula polyantha 
Primula vulgaris duplex, A variety or perhaps a hybrid plant with neat clumps of fresh 
green leaves about 5 inches high and tall stems to 8 inches high with heavy umbels 
of lovely yellow flowers. The flowers are hose-in-hose, or one growing out of an- 
other. Same soil and exposure as above. 
Primula vulgaris duplex rosina. Exactly the same as the preceeding except that the flow- 
ers are deep pink or red. Give it rich garden soil in shade or half shade. (pH 5-7) 
PRUNELLA. Self-Heal. (Labiatae, Mint Family) 
Prunella grandiflora. A large quickly growing evergreen mat of large oval leaves about 
3 inches high with huge heavy spikes of showy blue-purple flowers in June and 
July. An old rock garden subject that is still in favor. It is useful both for its sum- 
mer flowers and as a limited ground cover both in sun and shade. It is easy to grow 
in any ordinary garden soil. (pH 6-8) A good wild garden plant. 
Prunella grandiflora alba. A pure white flowered form of the preceeding with the 
blooming season extending into August and September. 
PTEROCEPHALUS. (Dipsaceae, Teasel Family) 
Pterocephalus parnassi. (Scabiose) From the mountains of Greece comes this rare and 
beautiful gray leaved plant that forms low spreading masses of deeply cut woolly 
gray leaves on intricately branched stems about 3 inches high. It is topped with 
a liberal sprinkling of lilac colored dense flower heads, much like the scabiose. It 
makes an excellent wall plant or rock garden subject. It requires a deep root run 
of gritty, well drained lime soil in full sun. (pH 7-8)
