March and September, and also by dividing 

 the roots at the same periods. 



J. montana. — A pretty hairy or downy 

 British annual 1-1^ ft. high, with obovate 

 oblong leaves ^—1 in. long. Flowers from 

 Jime to September, lilac-blue or whitish, 

 in hemispherical heads i-£ in. across. The 

 seaside form littoraUs is usually a biennial. 



Culture dc, as above. Increased by 

 seeds sown annually. 



J. perennis. — An elegant perennial 

 1-1^ ft. high, native of W. Europe. Leaves 

 rather hairy, lower ones obovate, upper 

 oblong linear. Flowers from June to 

 August, blue, in dense roundish heads. 



Culture dc. as above. Increased by 

 seeds and division. 



WAHLENBERGIA (^Tufted Hare- 

 hell). — A genus containing about 80 species 

 of annual, perennial, or woody-stemmed 

 herbs with alternate or rarely opposite 

 leaves. Flowers often blue and nodding. 

 Calyx tube adnate, hemispherical, turbin- 

 ate or obconical-oblong ; limb usually 

 5-parted, corolla bell-shaped, tubular, or 

 somewhat rotate, shortly or rarely deeply 

 5-oleft, very rarely 3--4-cleft. Stamens 

 free. Capsule inferior or half superior, 

 erect. 



Culture and Propagation. — Wahlen- 

 hergias (including Edraianthus) are beau- 

 tiful, strong-growing, free-flowering peren- 

 nials, eminently suited for the rockery or 

 flower garden. They are easily grown in 

 good sandy garden soil, but do not like 

 stagnant moisture at the roots. A sunny 

 airy situation suits them best. They 

 ripen seed freely, and if sown as soon as 

 ripe in autumn, a good supply of plants 

 will always be available. Division of the 

 root is not altogether successful unless 

 very carefully done. The roots are very 

 long, and unless they are carefuUy taken 

 up they are too much injured to develop 

 new ones readily. 



W. capensis {Ca/mpanula capensis). — 

 A S. African half-hardy annual 1-1 J ft. 

 high, with ovate lanoe-shaped, hairy, 

 irregularly toothed leaves 1-2 in. long. 

 Flowers in July, dark blue inside, spotted 

 with black bluisl^-green outside, drooping 

 at first, nearly erect afterwards. 



Culture and Propagation. — Being an 

 annual it is best to sow the seeds in gentle 

 heat in March and plant the seedlings 

 out at the end of May ; or the seeds may 

 be sown in cold frames when ripe, and the 



seedlings wintered under glass until the 

 following spring. 



W. gracilis (Campanula capillaris). 

 Australian Harebell. — A native of Aus- 

 tralia and New Zealand, 6-24 in. high. 

 Lower leaves spoon-shaped, toothed, upper 

 ones linear-oblong, entire toothed, or 

 sinuate. Flowers in April, variable in 

 size and form; blue, purple, or white, 

 about ^ in. long, 3-5-lobed. 



Culture dc. as above. 



W. graminifolia. — A beautiful Italian 

 species forming tiifts of long grassy leaves, 

 and masses of large purple flowers nestling 

 among the foliage during the summer 

 months. 



Culture dc. as above. This species 

 seeds freely and seedlings come up in 

 spring without any trouble. 



W. hederacea [Campanula hederacea) . 

 A British and European perennial with 

 thread-like creeping stems, and stalked, 

 roundish or heart-shaped, angled or ob- 

 scurely lobed leaves about | in. across. 

 Flowers in July and August, pale blue, j 

 in. across. There is a variety called cran- 

 moriensis. This species grows naturally 

 in bogs and damp wpods, and should there- 

 fore be given a, moist shaded place in the 

 border or rockery. 



Culture dc. as above. 



W. Kitaibeli. — A sturdy tufted peren- 

 nial about 6 in. high, native of Transyl- 

 vania, with purplish, softly hairy stems, 

 and linear awl-shaped, toothed leaves. 

 Flowers in summer, blue, tinged with 

 purple. 



Culture dc. as above. 



W. Pumilio. — A pretty Dalmatian 

 perennial 2-3 in. high, with tufts of 

 bluish tinted needle-like leaves \ in. or 

 more long. Flowers from May to July, 

 reddish-lilac or bluish, in great profusion. 



Culture dc. as above. A beautiful 

 rock plant. 



W. Pumiliorum. — A rare and beautiful 

 rock plant 2-3 in. high, like W. Pumilio, 

 with a more straggling habit, shorter and 

 narrower leaves, and longer-tubed soft 

 blue flowers which are produced in great 

 abundance in summer. 



Culture dc. as above. 



W. saxicola (W. albomarginata; W. 

 vinccefiora). — New Zealand Bluebell. — 

 A charming rock plant 2-8 in. high, 

 native of the New Zealand mountains.
