CLIMBERS AND TWINERS. 
365 
vases where trailing growth is required. Ordinary soil. In- 
creased by seeds sown in heat in March, hardening off the 
seedlings in June and planting out. Being perennials, cut- 
tings may be taken from the young shoots in August, rooted 
in sandy soil, and wintered in a warm greenhouse. 
Menispermum (Moonseed). — M. canadense is a hardy 
deciduous climbing shrub, a native of Canada, and a member 
of the Nat. Ord. Menispermacete. It is a rapid-growing plant 
with large kidney-shaped leaves and yellowish flowers borne in 
drooping racemes in summer. Its chief beauty lies in its 
foliage, and its value in the garden for the rapidity with which 
it will cover arbours, trellises, etc., especially those in shady 
spots, with foliage. Plant in autumn in ordinary soil. In- 
creased by seeds sown in sandy soil in a cold frame in 
spring ; by cuttings inserted in gentle heat in spring ; also by 
division of the roots. 
Passiflora. (Passion-flower). — Few hardy climbers are 
more beautiful than the blue Passion-flowers (P. caerulea), 
which originally came from Brazil. This species is not only beau- 
tiful when in flower, but also particularly attractive when laden 
with its golden, egg-shaped, fragrant fruit in autumn. In 
the South it grows flowers and fruits freely, on a warm wall, 
and frequently so also on arches, arbours and tiellises. Its 
white variety, Constance Elliot, is equally as hardy and showy. 
To grow it really well plant in a good bed of a mixture of 
loam, peat and leaf-mould. Very good results, though, may 
be obtained by planting in good ordinary soil. Plant in early 
spring. This plant is apt to. grow somewhat straggly. To 
obviate this make a point of cutting away entirely all weak 
shoots and shortening the strong ones of the preceding year 
to 6in. or a foot from their base in February. This will en- 
courage new growth and ensure plenty of flowers. Increased 
by cuttings of young shoots 4 tQ bin. long, inserted in sandy 
soil in a cold frame in spring or summer. 
Periploca. (Silk Vine). — P. grseca is a hardy deciduous 
twining or climbing shrub, with small greenish-black flowers 
possessing a by no means pleasing odour. It is a native of 
S. Europe, and belongs to the Asclepias family (Asclepiadeae). 
The Silk Vine is a rapid grower and quickly covers an arbour, 
pergola or trellis with a dense mass of foliage. We do not 
recommend it to be grown in small gardens. The stems die 
back in winter, hence these require to be cut back annually to 
live wood. Plant in ordinary soil in autumn. Increased by 
cuttings inserted in sandy soil in a cold frame in summer, or 
by layering the shoots.
