the vine and have a pleasant fragrance. It is one of the best of all 
fall-flowering vines, and hardy north; clings well to a chicken-wire 
trellis. 
The large-flowered section, of which Jackmani is perhaps the best 
known, is very popular for pillar or porch climbers. The flowers of 
this section are large and showy, running from pure white, through 
blue, to scarlet. Of this class, a serviceable purple is Jackmani; white, 
Henryi (Fig. 266); blue, Ramona; crimson, Madame E. André. 
A deep, mellow, fertile soil, naturally moist, will suit the require- 
ments of clematis. In dry times apply water freely, particularly for 
the large-flowered kinds. Also provide trellis or other support as 
soon as they begin to run. Clematis usually blooms on the wood of 
the season: therefore prune in winter or early spring, in order to secure 
strong new flowering shoots. The large-flowered kinds should be cut 
back to the ground each year; some other kinds may be similarly 
treated unless they are wanted for permanent bowers. 
The clematis root disease is the depredation of a nematode or eel- 
worm. It is seldom troublesome in ground that thoroughly freezes, 
and this may be the reason why it so often fails when planted against 
buildings. 
Coleus. — The commonest “foliage plant ” in window-gardens. It 
was used very extensively at one time in ornamental bedding and 
ribbon borders, but owing to its being tender has lost in favor, and its 
place is largely taken by other plants. 
Coleus is grown with the greatest ease from cuttings or slips. Take 
cuttings only from vigorous and healthy plants. It may also be grown 
from seed, although the types have not become fixed, and a large 
number of differently marked plants may be had from the same packet. 
This would not be a drawback in the winduw-garden, unless a uniform 
effect is desired; in fact, the best results are often secured from seeds. 
Sow the seed in gentle heat in March. 
Grow new plants each year, and throw the old ones away. 
Crocus (see Bulbs, p. 281). — Crocus is one of the best of spring 
bulbs, easily grown and giving good satisfaction either in the border 
or scattered through the lawn. They are also forced for winter (see
