 banks and rocky places. There are upright and very formal varieties 

 of it, the best being those sold as var. Hibernica, "Irish juniper," and 

 var. Suecica, "Swedish juniper." 

 Northern juniper, J. Sabina, var. procumbens .* 



One of the best of the low, diffuse conifers. 

 Dwarf Norway Spruce, Picea excelsa, hort. var. 



Several very dwarf sorts of the Norway spruce are in cultivation, 

 some of which are to be recommended, 

 Dwarf pine, Pinus pumilio. 



There are other desirable dwarf pines. 



IV. PERENNIAL CLIMBERS. 



A. Shrubby. 

 1. TENDRIL CLIMBERS, BOOT CLIMBERS AND SCRAMBLERS. 



Virginia creeper, Ampclopsis quinquefolia* 



The best vine for covering buildings in the climate of Michigan. 

 Plants should be selected from vines of known habit, as some indi- 

 viduals cling much better than others. 



Japanese ivy, Boston ivy, A. tricuspidata (A. Veitchii). 



Handsomer than the Virginia creeper, and clings closer, but is often 

 injured by winter in exposed places, especially when young. 

 Garden clematis, Clematis of various species. 



Plants of robust and attractive habit, and gorgeous bloomers. C. 

 Jackmanni, and its varieties, is one of the best. (7. Henryi (Fig. 185) 

 is excellent for white flowers. Clematises bloom in July and August. 

 Wild clematis, C. Virginiana* 



Very attractive for arbors and for covering rude objects. The pistil- 

 late plants bear curious woolly .balls of fruit. 

 Wild Clematis, C. verticillaris. 



Less vigorous grower than the last, but excellent. 

 Trumpet creeper, Tecoma radicans. 



One of the best of all free-flowering shrubs. Climbs by means of 

 roots. 



Frost grape, Vltis cordifolla. 



One "of the finest of all vines. It is a very tall grower, producing 

 thick, heavy, dark leaves. Its foliage often reminds one of that of 'the 

 moon-seed. Does not grow readily from cuttings.
