The crossvine (Bignonia capreolata) has large, 2-inch-long orange-red flowers that often attract butterflies and hummingbirds in the spring. The plant's leaves turn purplish in the winter. Plant it in acidic soil in USDA Zone 6 through Zone 10. It grows rapidly and will reach 30 to 50 feet long. Bougainvillea (Bougainvillea spp.) flowers may be purple, red, pink, orange, yellow or white. It needs a rich, loamy soil in Zone 9 through Zone 11. Let the soil dry out before you water again, and you'll have better flowers.
Passionflower (Passiflora incarnata) has purple and white flowers that turn into a sweet-smelling fruit. It grows about 10 to 15 feet and will die back to the ground in the winter. It is hardy in Zone 7B through Zone 11. The trumpet creeper (Campsis radicans) grows rapidly and will tolerate poor soil, heat, drought and wind. The only drawback is that it may need some extra support. It can reach lengths of 40 feet and has orange, red or coral flowers. It is hardy in Zone 4 through Zone 9.
Climbing hydrangea (Hydrangea anomala subspecies petiolaris) produces white flowers in the late spring. Older stems have a reddish bark that shreds to provide winter interest. It grows up to 80 feet long in USDA Zone 5 through Zone 8. The silver-lace vine or fleecevine (Polygonum aubertii) has small white flowers that turn pinkish. It has a good salt tolerance and will tolerate poor soil. It is hardy in Zone 4 through Zone 9. It is a twining vine and may need additional support.
If you had your heart set on ivy for your sunny location, you're limited to Boston ivy (Parthenocissus tricuspidata). Although it won't keep its leaves the way English ivy does, it does turn a brilliant red in the fall. It grows up to 10 feet a year until it reaches about 50 feet long. A close relative with similar growing habits is the Virginia creeper (Parthenocissus quinquefolia). Both are hardy in USDA Zone 6 through Zone 8. The wintercreeper euonymus (Euonymus fortunei var. radicans) is an evergreen option if you live in northern areas of Zone 5 through Zone 9. It prefers shady locations in southern areas. It grows about 15 feet long, but has reached as long as 50 feet.
