darker zone surrounding a whitish centre ; the habit is not pyramidal but 

 bushy, three feet high, and I can only liken it when in flower to a gigantic 

 Gilia tricolor. They can be propagated from root cuttings and also by 

 seed. Another method of propagation is to decapitate the crown in the 

 autumn, when in the following spring many shoots will be found coming 

 up, which can be easily separated. 



LATIFOLIA. — A British hedge plant, very plentiful in Sussex, 

 especially to the west of Steyning. "The garden forms of it seem to be 

 three in number, macrantha, alba, and the variety with whitish flowers 

 and blue centre. The large blue corollas are always admired, and in good 

 rich loamy soil the plant often attains a height of six feet. The finest 

 examples of this species were once shown me in Hertfordshire, where I 

 was called in to see some "curious Canterbury Bells," as the gardener 

 called them. 



I was greatly surprised to find a vast array of the white variety with 

 the blue centre : it was a splendid sight. I could hide myself amongst them 

 without bending. They were partly shaded by orchard trees (thinly 

 overhead) and were close to the New Kiver bank, which doubtless 

 accounted for their unusual beauty and vigour. Propagation by seed 

 and division. 



LACTIFLOBA. — One of the finest and most distinct of the 

 perennial border species. When well established it often attains a 

 heigh c of six feet. Flowers pale blue, in dense umbellate panicles, The 

 white variety seems to be a dwarfer but still very beautiful plant. Close 

 to this species, and probably a variety of it, comes 



CELTIDIFOLIA, rather more compact than lactiflora, but with 

 dense broad panicles of rich blue bells. It ought to be found in every 

 collection, as it keeps up the succession, coming in after the greater part 

 of the species are passing over. Both this and lactiflora require to be 

 planted at least two years before they attain their normal dimensions. 

 The foliage of these two species is of a pleasing pale green. 



BONONIENSIS. — A pretty species of moderate growth, with long 

 profusely flowered spikes of nodding bells, both in blue and white. A 

 really beautiful but little-known species. Height 2J to three feet ; pro- 

 pagation by division and seed. 



ALLIABI^FJ FOLIA. — Flowers white, pendulous on a one-sided 

 spike ; foliage heart-shaped and covered with tomentum. 



SABMATICA is rather like the preceding species, having pale blue 

 bells with ovate foliage. Both of them grow from two to 2h feet, and 

 are desirable plants in the border. 



PEBSICIFOLI A.— The Peach-leaved Campanula. A very well- 

 known plant, and one of the handsomest species, providing with its 

 numerous varieties some of the most useful and decorative of all the 

 perennials. The varieties are blue and white ; single cup ; saucer blue 

 and saucer white ; double blue and double white ; and gigantea alba 

 jrtena (Moerlieimi). The last named is a good Dutch novelty, but I 

 believe equally good forms have been raised by Mr, Ladhams at South- 

 ampton. The snow-white variety named Backhousci was an accidental 

 find of Mr. Potter's in a cottage garden in Yorkshire. Height two to 

 three feet. This species admits of division in spring or after flowering,
