 and more so than several other species. 



Cctinothiis lhiirsifli>nis. and the i)aler variety 

 urine IIS are now following in succession, and have for 

 company ('■ liusscUiauus, a vigorous, densely- 

 branched bush of garden origin, beai-ing abundant 

 short fascicles of dark blue flowers, and the bett^-r 

 known C. Vritrhicnus, always a delightful shrub, 

 either as a bush in the open or as a wall shrub, with 

 flowers of a light shade of blue. 



Ccrcocarpiis parvifoJius is an interesting shrub of 

 the liose family. An evergreen with obovate, veiy 

 distinctly nerved leaves, it has no merit as an orna- 

 mental flowering shrub, yet now, with many corymbs 

 oi small, greenish-yellow flowers, chiefly comj)ose<l 

 of a woolly cah'X, numerous stamens, and a protrud- 

 ing stj-le, it certainly adds to the interest of a 

 shrubbery. 



Pittosporuni tcntiifoUu))) , near by, is a handsome 

 evergreen with ornamental leaves, and now carrying 

 an enormous crop of chocloate-brown flowms. 



Rhododendrons. 



rihoclodcudron caUimorplurn is as jet little known 

 in gardens, but will be sought after in the near future. 

 It is inclined to suffer -with other early flowering 

 species from spring frosts. The stalked, oval leaves 

 are glaucous below and dark green above. The bell- 

 shaped flowers, produced in loose trusses of about 

 six flowers each, and deep pink in the bud stage, the 

 expanded flowers fading to a fine rose pink. Of 

 dwarf habit, making short annual growths, it is a 

 useful species for a restricted space, .such as about 

 a rock garden or the edge of a bed devoted to other 

 Rhododendrons and plants requiring similar condi- 

 tions. The species was illustrated in TiiTsn 

 Gardknixg of February, 1920, together with a dc- 

 scriptive note by Mr. Armytage ^Vfoore. 



Tihododrudron Lnderii Patience is one of a nvunlx'r 

 distributed by the late Sir Edward Txider. They are 

 among the most magnificent of all Pihododendrons, 

 with trusses of 7-8 flowers, each flower six inches or 

 more across. In the variety under notice the Inids 

 are pink, the expanded flowers almost pure Mhilr 

 with just a suspicion of pink at the rim of tlu^ 

 corolla. 



7?. Lodcrii Pretly Polly, described and figured in 

 this .Tournal in -luly, 1919', has more pink in the open 

 flower, and is just in loud now in the middle of May. 

 Tihile Patioicr is full out and some flowers falling. 



};. Sdirsiir is also in full flo\\<r now. The shortly 

 stalked leaves arc tapered to Ixitb ends and arc scaly 

 below. The flowers are rosy lilac, the upper segment 

 thickly s])o(tcd with greenish brown spots. A \iso- 

 ful if no( liiilliaut spi^cics, appai.ntly ipiite hardy.

Rock Plants. 



Uahkumca itMoi.oii.Nsis is oiif of the indispt'iisablfs 

 of every rock garden which can show a shady nook 

 and a i)Ocket of moist soil, (liven a northern aspect 

 and a nK)re or less vertical crevice, so that the 

 leaves will not be resting on the bare soil, there is 

 every ho])e <if JluhrrUa flourishing. In addition, it 

 is (piite i)ossil)le that a moist atmosphere is. helpful, 

 so. where any ditfieulty is experienced, it might be 

 advisable to form a rock pool or moist bog bed 

 below where the Haherha is planted, to keep the 

 air in the vicinity' cool and moist. The ordinary 

 species is //. rZ/ix/opcJis/s, which forms rosettes of 

 dark gieen. hairy leaves with toothed margins and, 

 pushing up between the leaves in ^^ay, come the 

 flower scapes carrying several lovely tubular flowers, 

 lilac or lavender with yellow throat, providing a 

 rare feast of beauty when a good colony of plants 

 is flowering freely. Seedlings and collected plants 

 vary in form of leaf and size of flower. The finest 

 form, perhaps, is H. Fcrdinandi-Cohurgi, with 

 broader, more fleshy- leaves and larger flowers, the 

 mouth of the tube being wider. //. rhodnpenHin 

 virfjinaVin is a pure white variety of considerable 

 charm, but the flowers are smaller, in the writer's 

 opinion, it is certainly not superior to the type. 



Hclichrysiun bcUidiotdes is a New Zealander and 

 likes a sunny position in well drained soil. It forms 

 many long shoots clothed with small leaves, dark 

 green above and woolly below, and from early sum- 

 mer onwards bears numerous white flowers of fine 

 elTect. 



II. frigidam is a tiny gem from Corsica and is 

 frankly not hardy. The short shoots are densely 

 furnished with tiny grey leaves, and in .summer it 

 bears pure white flowers, when it is a truly pretty 

 plant. In the moraine it grows well in summer but 

 languishes in s])ite of covering during winter, so it 

 is not to be generally recommended. 



Hclonian huUafa is a plant for the small bog or 

 stream side. It forms a rosette of fleshy green 

 leaves, and from among them it pro<lucos a spike 

 some eighteen inches to two feet high, at the top 

 of which a dense mass of pink flowers imfolds. A . 

 group of several plants is always an object of ad- 

 niiration. 



Hruchcraft, now so popular in the herbaceous 

 border, ai-e. in the garden varieties, rather too 

 robust for all but the largest rock gardens. Never- 

 theless Heuchera mnguinea, when it can be obtained 

 true or not too far removed from the type, is quite 

 n good rock plant, producing a rare bit of colour. 

 Such varieties as H. savguinra " Sanghitit " and 

 II. sanguinca " Walker's Variety,'' retain sufficient 

 of the Hangiiiiica character to make them suitable 

 for rock gardens. 



Hypericums are among tjie important plants -of 

 the rock gai'dcn. and though all, in general cultiva- 

 tion, .ore yellow, they vary considerably in habit, 

 and all may be increased by seeds or cuttings.
