 compact slightly glaucous symmetrical 

 tufts, 12 to 1 8 in. high. May be grown in 

 any soil, but the slender flower-stems, 

 which appear in May and June, should 

 be pinched off. Not only in aspect does 

 this bushy little tuft resemble the Maiden- 

 hair Fern, but its leaves when mingled 

 with flowers are pretty ; stififer, however, 

 and more lasting than Fern fronds. T. 

 minus would look well isolated in large tufts 

 as an edging, in borders, or in groups of 

 dwarf subjects. Division. T. adiantifolium 

 is similar. T. tuberosum is about 9 in. high, 



be associated with it and other border 

 plants of the season. It grows best in 

 good soil in an open situation, and is a 

 native of California, also other parts of

 pagated by seeds. T. barbata is a beau- 

 tiful Himalayan species with purple 

 flowers.

 among them, as all have finely-cut 

 foliage. A good kind with fern-like 

 foliage is T. aquilegifolium, which is 

 about 4 ft. high, and grows vigorously 

 in any soil. There are two or three 

 varieties of it, one (atropurpureum)
