226 ROCK GARDENING FOR AMATEURS 



reptans, are rock-garden flowers. These are happiest 

 in a light loamy soil and a sunny spot. Geum montanum, 

 widely distributed on European mountains, has big 

 Strawberry-like leaves that hide a somewhat woody, 

 low stem ; it bears, in May, fairly large golden-yellow 

 blossoms. Frequent top dressing and occasional re- 

 planting are necessary to keep the stem well covered. 

 Geum reptans is a pretty little plant that produces runners 

 like a Strawberry. It bears yellow flowers in June. 

 Propagation is effected by seeds sown in spring, or by 

 division in late summer. 



Globularia (Blue Globe Daisy). The Globularias 

 are generally of low, somewhat shrubby growth, having 

 glossy dark green leaves and rounded heads of blue 

 flowers. They are native chiefly of Southern Europe, 

 and belong to the natural order Selagineae. The choicest 

 is G. nana, which is only about half an inch high and has 

 Thyme-like leaves and heads of bluish- white flowers. 

 The next best is G. cordifolia, which makes a carpet of 

 small leaves studded with round clusters of little blue 

 flowers. G. bellidifolia, G. nudicaulis, and G. trichosantha 

 are moderately good, and have also blue or bluish-white 

 flowers. G. vulgaris is the tallest, and the least choice 

 for the rockery. All flower in early summer. They 

 cannot be reckoned choice rock plants. They thrive 

 in an open, sunny spot and a well-drained compost of 

 sandy loam and leaf-soil. They are increased by seeds, 

 sown under glass in spring ; by cuttings in spring and 

 summer ; and by division as soon as the flowering is over.
