ALPINE FLOWERS FOR GARDENS 



243 



Iberis jucunda. A beautiful and very 

 dwarf Candytuft, with soft, rosy, lilac- 

 flowers in corymbed clusters, on slender 

 twisted stems, over small sea-green foli- 

 age, the plant rarely more than 4 inches 

 or 5 inches high. It is easily raised from 

 seed, and should be cultivated in numbers, 

 so as to form good- sized patches. 



INCARVILLEA. Distinct and 

 beautiful perennials of recent intro- 

 duction, probably hardy, coming from 

 the high mountains of China, where 

 there are, no doubt, many other 

 beautiful things in Nature's vast store- 

 house. Though the habit is bold, 

 they may very well find a home on 



from two to a dozeii or more flowers, 2 

 inches long and 2 inches wide, rich 

 rose, with a few purple streaks, and a 

 tinge of yellow in the throat. 



Mr C. M. Mayor, of Paignton, Devon, 

 sending me a photo of a very fine plant, 

 says : " It was planted in deep, light, 

 ordinary garden-soil, in a sunny spot, the 

 crown covered with sand to a depth of 

 3 inches. I found that mulching with 

 rotten manure or other moisture-holding 

 material, if in contact with the bases of 

 the frond-like leaves, causes them all to 

 rot off a rot which quickly spreads to 

 the tuberous root itself." 



Incaryillea grandiflora resembles I. 

 Delavayi in general characters, differing in 

 its shorter leaves, more rounded leaflets,

the rock-garden until more plentiful 

 and better known. They, so far as 

 now known, flower in summer, are of 

 easy culture in ordinary soil, and do 

 not seem difficult of increase. 



Incarvillea Delavayi. We owe the in- 

 troduction of this beautiful plant to the 

 Abbe Delavay, who found it in Yunnan, 

 Western China, at a height of 8,000 feet 

 to 11,000 feet. It has a stout root-stock, 

 with a very short subterranean stem, from 

 which spring the bright green leaves, each 

 a foot or more long. The flower-scape 

 varies from a foot to 2 feet, and bears 



bearing only one or two large flowers, 

 whilst the colour is a deep rose-red. 



I. Olgae is hardy in the southern 

 counties, and has bright green pinnate 

 leaves and, borne upon the upright ends 

 of the branches, panicles of rose-pink 

 tubular flowers, .each an inch long and 

 wide. Turkestan. 



There are other beautiful species of these 

 not yet introduced or sufficiently tried. 



IONOPSIDIUM ACAULE (Violet 

 Cress). This, being an annual plant, 

 is only introduced here in consequence
