A Greenhouse Climber 
2 feet. — Well-known, graceful plants bearing 
clouds of pink bloom ; seed-growers have ob- 
tained desirable salmon-coloured varieties, but a 
good form of the original pink is the most refined 
in colour. All the Clarkias are good for cutting. 
They should be sown in spring where they are to 
flower. 
Cobtea scandens. — This very useful green- 
house climber, though in fact a perennial, is 
commonly treated as a biennial. In one season 
it will cover a large space. The large, wide, 
funnel- or cup-shaped flowers are of a rather dull 
purple colour, but are strikingly handsome. It 
should be grown against a south wall or a trellis 
in a warm aspect. Sow in July ; keep in pots 
in frame or cool greenhouse through the winter 
and put out at bedding time. 
Collinsia bicolor ; h.a. ; i foot. — A charm- 
ing old garden annual with lilac and white 
flowers in whorls. 
Collomia coccinia; h.a. ; i foot. — Soft 
scarlet flowers in heads much like Bouvardias. 
May be trusted to sow itself as it nearly always 
reappears where it has once been grown. 
Convolvulus major is more properly 
IPOMiEA purpurascens, but is commonly known 
by the first name. A well-known climber, 8 to 
io feet ; purple and pink ; there is also a white 
variety. It can be sown in place, but is rather 
better sown early in heat and planted out in
