314 MANUAL OF GARDENING 



Woody perennial climbers. 



(Climbing shrubs, the tops not dying down in fall except in climates 

 in which they are not hardy.) 



a. Tendril-climbers, root-climbers, scramblers, and trailers 



Virginia creeper, Ampelopsis quinquefolia.^ 



The best vine for covering buildings in the colder climates. Plants should 

 be selected from vines of known habit, as some individuals cling much better 

 than others. Var. hirsuta,* strongly clinging, is recommended by the experi- 

 mental station at Ottawa, Canada. Var. Engebnanni* has small and neat 

 foliage. 



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 j^oung; in northern regions, tops 

 should be protected for first year or two. 



Variegated i\y, A. heterophylla var. elega7is {Cissus variegata). 



Handsome delicate hardy grape-like vines with mostly three-lobed blotched 

 leaves and bluish berries. 



Garden clematis, Clematis of various species and varieties. 



Plants of robust and attractive habit, and gorgeous blooms; many garden 

 forms. C. Jackmani, and its varieties, is one of the best. C. Henryi (Fig. 

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



Wild clematis, C. Virgim'ana.^ 



Very attractive for arbors and for covering rude objects. The pistillate 

 plants bear curious woolly balls of fruit. 



Wild clematis, C. verticiUaris.^ 



Less vigorous grower than the last, but excellent. 



Japanese clematis, C. paniculata. 



The best late-blooming woody vine, producing enormous masses of white 

 flowers in late summer and early fall. 



Trumpet creeper, Tecoma radicans.'^ 



One of the best of all free-flowering shrubs; climbs by means of roots; 

 flowers very large, orange-scarlet. 



Chinese trumpet creeper, T. grandiflora (Bignonia grandiflora). 

 Flowers orange-red; sometimes scarcely climbing.
