[Illustration: Fig. 265. Sweet pea.]
Perennial herbaceous climbers.
(The tops dying down in fall, but the root living over winter and
sending up a new top.)
a. Tendril-climbers or root-climbers
Everlasting pea, Lathyrus latifolius.
Clematis of various species, as C. aromatica, Davidiana, heracleaefolia
(C. tubulosa), are more or less climbing. Most of the clematises
are shrubs.
May-pop, Passiflora incarnata.*
Not reliable north of Virginia.
Wild Gourd, Cucurbita fœtidissima (Cucumis perennius).*
Excellent strong rugged vine for covering piles on the ground.
Mexican rose, mountain rose, Antigonon leptopus.
Root tuberous; a rampant grower, with pink bloom; outdoors South,
and a conservatory plant North.
Kenilworth ivy, Linaria Cymbalaria.
A very graceful little perennial vine, re-sowing itself even where not hardy;
favorite for baskets.
b. Herbaceous twiners
Hop, Humulus Lupulus.*
Produces the hops of commerce, but should be in common use as an ornamental
plant.
Chinese yam, cinnamon vine, Dioscorea divaricata (D. Batatas).
Climbs high, but does not produce as much foliage as some other vines.
Wild yam, D. villosa.*
Smaller than the preceding; otherwise fully as good.
[Illustration: Fig. 266. Clematis Henryi. One-third natural size.]
Ground-nut, Apios tuberosa.*
A bean-like vine, producing many chocolate-brown flowers in August and
September.
Scarlet runner and White Dutch runner beans, Phaseolus multiflorus.
Perennial in warm countries; annual in the North.
Moonflowers, Ipomcea, various species.
Some are perennials far South, but annual North.
Hardy moonflower, Ipomœa pandurata.*
A weed where it grows wild, but an excellent vine for some purposes.
Wild morning-glory, Rutland beauty, Convolvulus Sepium* and California
rose, C. Japonicus.
The former, white and pink, is common in swales. The latter, in double
or semi-double form, is often run wild.
Madeira vine, mignonette vine, Boussingaultia baselloides.
Root a large, tough, irregular tuber.
Mikania, climbing hempweed, Mikania scandens.*
A good compositous twiner, inhabiting moist lands.
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 experimental station at Ottawa, Canada. Var.
Engelmanni* 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 young; in northern
regions, tops should be protected for first year or two.
Variegated ivy, Ampelopsis heterophylla var. elegans (Cissus
variegata).
Handsome delicate hardy grape-like vines with mostly three-lobed
blotched leaves and bluish berries.
