310 ALPINE FLOWERS. Part II. 



drained soil ; it is well worthy of a place on the rockwork, but 

 decidedly the best thing to do with it is to try and naturalise 

 it, on bare spots in open rich woods — positions like those in 

 which it is found wild in North America. Propagated by divi- 

 sion, and flowers in March. 



SANTOLINA ISCKSK.— Hoary S. 



A SMALL silvery shrub, with numerous branches and narrow 

 leaves, the whole plant covered with dense white down, form- 

 ing neat prostrate tufts of edgings in the flower-garden. The 

 ' flowers are rather small, pale greenish-yellow, and in no way 

 ornamental, but the plant is likely to be popular from its neat 

 habit and silvery hue, and it grows readily in ordinary soil 

 on the level border, and may be tastefully used on slopes of 

 rockwork. It is considered a variety of the better known S. 

 ChamcEcyparissus, the Lavender Cotton. This and its other 

 variety squarrosa are suitable for very large rockworks, banks, 

 &c., but, forming spreading silvery bushes, two feet high, in suit- 

 able soil, are not suited for intimate association with very dwarf 

 alpine plants. 



Other species of Santolina are suited for hke purposes, 6', 

 pectinata and 5". viridis, for example, forming bushes somewhat 

 like the Lavender Cotton. Santolina alpina is of more alpine 

 habit, forming dense mats quite close to the ground, from which 

 spring yellow button-like flowers on long slender stems. It grows 

 in any soil, and may be used on the less important parts of 

 the rock-garden. Cuttings of the shrubby species strike readily, 

 and .y. alpina is easily increased by division. 



SAPONAEIA OCTMOIDES.— i?o<:,J S. 



A BEAUTIFUL trailing rock-plant, with prostrate stems and an 

 abundance of rosy flowers, so densely produced as to completely 

 cover the cushions of leaves and branches. It is easily raised 

 fr6m seed or from cuttings, thrives in almost any soil, and is one 

 of the most Valuable plants we have for clothing the most arid 

 parts of rockwork, particularly in positions where a drooping 

 plant is desired, the shoots falling profusely over the face of the 

 rocks, and becoming masses of rosy bloom in early summer, and
