246 ALPINE FLOWERS AND ROCK GARDENS. 



dealt with in a special chapter. It is unnecessary to 

 repeat the cultural remarks, but it may be well to give 

 the names of a few good sorts. Marliacea Albida is a 

 good white ; M. chromatella a desirable yellow ; and W7n. 

 Doogue a good red. Odorata is a fragrant white species. 

 All these are hardy, and suitable for a garden pool. 

 There are many beautiful hybrids. 



(ENOTHERA (Evening Primrose). — Every flower 

 lover knows the Evening Primroses, whose large yellow 

 or white blossoms produce such a beautiful effect. 

 The larger species are not compact enough for the rock 

 garden, but there are several admirably adapted for 

 it. They are American plants, hardy, and very pro- 

 fuse in blooming. They revel in a cool, moist soil, but 

 they are not really particular, so long as the soil is not 

 poor and dry. The majority can be raised from seed, 

 which may be sown in a frame in spring, or even out 

 of doors. The perennials may be propagated by 

 division between autumn and spring. One of the best 

 species for our purpose is caespitosa, which is also 

 known as marginata and eximia. It grows nine inches 

 to a foot high and bears white, scented flowers in 

 summer. Fruticosa Youngii is a fine variety with rich 

 yellow flowers, which it bears in succession for many 

 weeks in summer and autumn. It is a day bloomer. 

 Taller than the preceding, it yet does not exceed two 

 feet high. Taraxaci folia is a fine trailer, with large 

 white flowers. It is not quite so hardy as some of the 

 species and needs a sheltered place and warm loamy soil.
