flov/ers in small rounded heads in great profusion in April, Alay, 

 and June. Best adapted for clothing rockwork, edging, small 

 beds, or for the front hnes in mixed borders. Native of Sicily. 



I. Garrexiana (Gartrx's Candytuft), — This is one of the least 

 valuable of perennial Candytufts, but one of the most commonly 

 cultivated. It comes very near the Evergreen Candytuft, and 

 is regarded as a variety of it; but the heads of flower are smal- 

 ler, and from the tendency to elongate that the racemes have 

 after flowering, it assumes rather a seedy aspect at the end of 

 the flowering season. But it is nevertheless a valuable sort, 

 being very tenacious of place once it gets a hold, and a free 

 grower, and consequently more useful for naturalising on dry 

 rocky places where some of the more choice sorts would not so 

 easily establish themselves. It grows in close carpet-like masses 

 about 6 to 9 inches high, flowers in April, May, and June, and 

 is a native of Piedmont and Spain, and probably of other parts 

 of Europe. 



I. gibraltarica {Gibraltar Candytuft). — This is one of the 

 most ornamental of the group. It grows from 9 inches to i 

 foot high, in close tufted manner, with leaves, flowers, and 

 flower-heads considerably larger than those of any other Candy- 

 tuft known to cultivation. The leaves are large, dark green, 

 oblong, and increasing in breadth towards the point; and the 

 flower-heads are close and broad, and have no great tendency 

 to grow out into seedy racemes. This is a very rare plant in 

 cultivation yet, and has not been sufficiently tried throughout 

 the country to prove its adaptabilit}' to our climate at all sea- 

 sons. It will be found best suited for culture on warm shel- 

 tered rockwork in sunny positions. Flowers white, shading off 

 in age to pinkish lilac, and appearing in May and June. Na- 

 tive of the south of Spain. 



I. Pruiti {P?'uifs Candytuft). — This being undoubtedly hardy 

 and little inferior to /. gibraltarica in point of size of flov/ers, and 

 being also pure white, is one of the brightest and best of the 

 genus. It grows about 9 inches high, producing dense masses 

 of dark-green foliage, rather large in size, and oblong in shape. 

 The flowers are large in compact heads, not elongating much 

 in flowering, and appearing in May and June. Native of Naples 

 and other southern countries of Europe. 



I. sempervirens {Evergreen Candytuft). — This species is 

 widely distributed and well known in gardens in this country. 

 It grows in compact, carpet-like, pale-green masses, producing 

 a great abundance of pure white flowers in small heads, which 

 have the objectionable feature of elongating during the process 

 of and after flowering. One of the most useful, succeeding well
