Herbaceous Plants 299 



There are several t}^es of sweet peas, i.e., garden, winter- 

 flowering (for growing in greenhouses), and the dwarf or 

 cupid. There are a great many varieties of the garden t^pe, 

 but at the present time the waved or Spencer varieties are 

 the best. The winter-flowering varieties are sometimes 

 planted outside for very early flowers, but are surpassed by 

 the garden varieties in size of flowers. The cupid sweet peas 

 grow about 8 inches high and are suitable for edgings. 

 They succeed on dry, light soils, and like more heat than the 

 other sweet peas. They succeed better in California than 

 elsewhere. 



Tender Annual Climbing Plants 



Among the best tender climbers for flowers, are canary- 

 bird flower {Tropceolum peregriniim), cardinal climber 

 (Ipomcea Quamelit hyhrida), cobea, Cyprus vine, hyacinth 

 bean {DoUchos Labi ah), moonflower, morning glory, nas- 

 turtium and scarlet runner bean. 



Some vines are desirable for their rampant growth, i.e., 

 wild cucumber or balsam apple {Echlnocystis lobafa), and 

 various species of gourds. These may be used for temporary 

 screens or for covering old sheds, etc. The hop-vine may be 

 similarly used. The balloon-vine {Cardiosperjnum Hali- 

 cacabiim), has interesting fruits. Some vines have a peren- 

 nial root, but the top is annual, i.e., allegheny vine (Adiumia 

 ftingosa), cinnamon vine (Dioscorea Batatas) ^ and Japanese 

 kudzu vine {Pueraria Thunhergiana). The best climber 

 for a very warm situation is maderia vine {Boussiugaultui 

 baselloides). This vine has tuberous roots which must be 

 lifted and stored during winter. It is a tender vine, which 

 attains from lo to 20 feet in a season, and bears fragrant 

 white flowers in the autumn. In the North, it should 

 be planted in full exposure to the summer afternoon sun. 

 Because of its tidiness, it is suitable for planting on porches.
