The Bignonias are nearly all either climbers or twiners. They are vigorous growers and have gorgeous trumpet or funnel-shaped flowers, some of them possessing flower-tubes six inches in length. These handsome cumbers are excellent plants for covering walls, growing over old stumps of trees, forming screens or trellises, etc. They will grow in any good garden soil, preferring however a sheltered situation. A wall facing the east is adapted for their full development.
This is another genus, which the gardeners of California have introduced from the greenhouses of the East and from Europe, now giving splendid effects in our favored State. Bignonia capreolata (a native of the Southern United States) is one of the hardiest and has orange-colored flowers. This species has a variety, with dark-red flowers, also a very desirable climber. Bignonia Cherere is a fine species bearing quantities of brownish-orange flowers. Bignonia diversifolia bears yellow and Bignonia floribunda purple flowers. Bignonia Tweediana, one of the best of the genus, with pretty lance-shaped leaves, has yellow flowers and is an elegant climber of rapid growth. Bignonia venusta bears glorious masses of blossoms and should be in every collection.
The Bignonia is propagated by cuttings placed in a cold frame during August or September in soil composed of one-half sand, one-quarter leaf-mold and one-quarter good loam, well mixed together, or by seeds sown, in Spring, a quarter of an inch deep.
