The flowers are followed by seedpods, up to 5 inches in length, that persist through the winter. The Trumpet Vines can be used as a wall cover or screen on a fence, and are excellent for attracting hummingbirds and butterflies. The Trumpet Vines often bloom all summer long.
They are easy to grow in full sun to partial shade on any well drained soil including clay. They are drought tolerant and too much water during summer may encourage excessive growth at expense of flowering. During drought, they should only get an occasional deep watering. The Trumpet Vines are rarely bothered by pests, disease, rabbits or deer. Adding bonemeal to soil during spring will help encourage blooming. Trumpet Vines love hot humid summers, and in cool summer climates such as the British Isles, they must be planted in a warm, sunny site protected from wind to get a worthwhile display of blooms.
Propagation is from seed or with cultivars, from semi-ripe cuttings taken in summer or root cuttings. Cut back to 6 inches in height when planting and plant deep to encourage new growth.

Campsis grandiflora ( Chinese Trumpet Vine )
Shorter in stature, reaching a maximum vining height of 50 feet, though rarely exceeding 20 feet. Some records include: fastest recorded growth rate - 10 feet.
Very long lived, these vines can exceed 100 years. Native to China and Japan, the Chinese Trumpet Vine is not a self aerial rooter and needs support such as a trellis to climb.
The pinnate leaves, up to 12 inches in length, are composed of 7 to 9 toothed, ovate leaflets. The foliage is deep green.
It has striking orange-red flowers that are much larger ( up to 4 inches across ) than Campsis radicans.
Hardy zone 7 to 9, Korean seed source should be hardy north to zone 6.

Campsis radicans ( American Trumpet Vine )
A very fast growing, very large vine native to sandy woodlands and floodplains in eastern North America ( from Nebraska to southern Wisconsin to central Michigan to southern Ontario to Pennsylvania & New Jersey; south to central Texas to central Florida ). It is endangered in the wild in Canada, being most abundantly found around Leamington, Point Pelee, Pelee Island and formerly around Chatham. It was also abundant on the Ohio shore during the 1800s and still is fairly abundant there. The American Trumpet Vine climbs with its aerial roots which attach to tree trunks and brick. Some records include: fastest recorded growth rate - 10+ feet; largest on record - 153 foot vining height with 6 inch trunk diameter. With average growing conditions; it is generally much smaller and can be pruned to even smaller size.
The pinnate leaves, up to 12 inches in length, are composed of 7 to 11 toothed, ovate leaflets, up to 4 inches in length. The foliage is deep green lightening to yellow or yellow-green during autumn.
The scarlet-red, trumpet-shaped flowers, up to 4 inches in length, are borne early summer. The flowers are borne in terminal clusters of 4 to 12.
They are followed by seedpods, up to 5 inches in length, that persist through the winter.
Hardy zones 4 to 9; in Ontario, it is hardy to far far north as Ottawa. At the northern fringes of its range, a severe winter may cause severe dieback - just cut to near groundlevel in early spring and it most certainly will grow back and FAST!
