These are vigorous woody deciduous climbers much valued in gardens because they flower from late summer and on into autumn. In hotter summers the flowers will appear by early July. There are two species; Campsis grandiflora from China and Campsis radicans from SE America.Campsis have the great attribute of producing aerial roots and they are therefore self-clinging on a wall without requiring any specific supports. They will grow equally well up a mature or dead tree where there is enough light for them to develop fully and flower. Similarly they can be trained on a trellis or pillar or over a metal frame. Here however your plants will need to be pruned into shape at the end of each season or in the spring. Campsis can easily produce several flowering shoots of 4-6ft long each season. As you would prune a vine back into shape on its supports so you should constrain, cut back and tie in your selected campsis shoots while removing others completely.
Once it's established, trumpet vine watering needs are minimal to moderate. during the summer, it needs about an inch (2.5 cm.) of water per week, which is often taken care of naturally by the rain. if the weather is especially dry, you may need to water it once per week yourself.
Partial sun generally means less than six and more than four hours of sun per day. Plants for partial sun will do well in a location where they receive a break from the sun each day. They like the sun but will not tolerate a full day of it and need at least some shade each day.
Trumpet vine's natural range is the hot, humid regions of the Southeast, but it will do well throughout the hardiness range. In dryer climates, the plant is easier to control.
Choose a pot with drainage holes, which also ensures potting soil doesn't stay too wet after watering your houseplants. The excess can freely escape out the bottom of the container, allowing oxygen to make its way to plant roots.
