The lovely trumpet-flower, Bignonia venusta, is a gorgeous, ornamental, climbing plant belonging to the natural order, Bignoniacese. It is a native of South America, from whence it was introduced in 1816. It is a deciduous greenhouse climber, attaining a length of over fifty feet, producing its bright orange-colored flowers in large terminal clusters from February to April. In order to flower this Bignonia to perfection it is absolutely necessary to plant it in a well prepared border of rich, loamy soil, and where its roots can obtain some warmth from the heating apparatus. It also must have an abundance of room for its roots, and likewise for its branches; for if these essential requisites are not given it, it must not be expected to flower well. It also requires to be properly pruned ; young plants three or four years old will flower nicely if they are properly pruned. In pruning, use a little judgment; cut back all weak and unripened wood to one eye, retaining as much of the strong and well-ripened wood as possible. All branches that are retained should be neatly tied up, spreading them out as much as possible, and as they increase in growth they should be kept tied.
Do not pinch back the young shoots on any account, but, if possible, allow them to ramble at will.
During its season of growth water should be freely given, and the plant frequently syringed, and when in full growth liquid manure water should be given once a week if possible. During the summer season, or when the plant is at rest, give only water enough to prevent the plant from becoming absolutely dry. Pruning is best done just before the plant starts into growth. It is altogether useless to try to flower this Big-nonia as a pot plant, - for if either the roots or branches be limited as to room, the result will be very discouraging to the person attempting its cultivation.
