ROCK GARDENS 



p. proctimbens.—Oi creeping habit, and brownish foliage. 

 Panicles of purple flowers in June from its prostrate growth. 



P. reptans. — Creeping habit and rapid growth, covering the 

 ground and rocks with its soft green foliage, about an inch high. 

 The purplish-rose-coloured flowers are borne in clusters on stems 

 4 to 6 inches high. Easily increased by division. 



P. Stellaria. — Forms a fairly compact tuft of narrow leaves, with 

 spikes of bluish-white, star-like flowers. Quite distinct. 



P. subulata. — Of dwarf, prostrate habit, forming a compact ever- 

 green mass, about 6 inches high. The leaves are awl- shaped and 

 very numerous. The flowers are rose-coloured, with a dark eye, so 

 freely produced as to hide the plant. It is of rapid growth, and very 

 hardy ; the only thing it dislikes is excessive drought. This is the 

 type of the indispensable creeping, mossy Phlox, of which endless 

 varieties are in cultivation, and are amongst the most valuable 

 plants there are for the rock garden, and should be freely grown 

 either to cover a bank or to clothe the face of a rock. They are all 

 lovely, and of the easiest culture. A selection should be made from 

 some catalogue. Mr T. Smith of Newry has a remarkably fine 

 collection, and many of the most beautiful hybrids are of his 

 raising. 



Physaria Didymocarpa (Cruciferae) 



Hot, dry position in very sandy loam. Curious large, succulent, 

 glaucous leaves, growing about 6 inches high, and yellow flowers. 

 A recent introduction, 



Phyteuma (Campanulaceae) 



Pretty plants for the rock garden, of the Bell-flower order. 



P. co?nosum. — Requires a warm, sunny chink in well-drained, very 

 calcareous, sandy soil. It should have plenty of root room, and 

 should be so placed that water cannot lie about and rot its crown. 

 The leaves are dark green, and only grow about 2 inches high. 

 The flowers are deep purple and of a curious shape, and are borne 

 in flattish heads on very short stems. It is quite hardy, though 

 having the reputation of being diflicult to grow ; but with plenty of 

 lime rubbish and good drainage there should be no trouble. Slugs 

 are particularly fond of this plant, and if not guarded against will soon 

 destroy it. One of the gems for a choice spot in the rock garden. 



P. pauciflorum. — Light sandy, calcareous soil in sun. Forms a 

 compact little tuft of narrow leaves, and has heads of deep blue 

 flowers. Diflicult to cultivate, but very attractive. 



P. hemisphaericum and P. orbiculare are very similar to the last- 

 named, but not quite so choice, though both are good rock plants 

 for a limestone soil.
