Cold hardy

Also known as A. x hybridum Fireball, and Abutilon Biltmore Ballgown, this is one of the many lovely hybrids between A. darwinii and A. striatum, with maple-like leaves and bell-flowers whose petals are recurved, turning in slightly at the bottom. Flowers are fiery red, as one would imagine, with prominent red veins accenting the surface. Happy plants can reach 8-10 ft tall, though pruning easily adjusts the size. Best with plentiful summer water and fertilizer. Less hardy than many, preferring temperatures that only occasionally drop into the 20s F, USDA zone 9. Placement out of wind with overhead protection and plentiful mulch help in less than balmy climates.

One of the most desirable symbols of Tropics, Alpinia purpurata, red ginger, also called ostrich plume and pink cone ginger, are native Malaysian plants with showy flowers on long brightly colored red bracts. They look like the bloom, but the true flower is the small white flower on top. Red Ginger grows in Hawaii, and many Central American nations, including Belize. It is also found in Samoa, where it is the national flower, and is locally called "teuila." It prefers partial shade and moist humid conditions, although it can tolerate full sun in some climates. It tends to like to be well watered and not left to dry out. Ginger can also be grown as a houseplant and its cut flowers can be used in arrangements.

The Aristolochia gigantea will inspire a sense of marvel to anyone who gazes upon it. This truly spectacular blossom produces a pouch that in some cultivars is almost 2 feet long and more than a foot across. Ivory veins network across a burgundy velvet background as the flower unfurls. Heart-shaped, light green leaves, about 6 inches in length, adorn this easy-to-grow vine. The plant blooms at a young age and grows in full sun or partial shade.
In some sources, Aristolochia gigantea is considered as Aristolochia grandiflora var. Hookeri. The cultivation of Aristolochias is undemanding. Sun lovers that appreciate some shade in hotter inland areas, they adapt to any soil that drains well. Any pruning necessary to contain or shape the plants should be done in late winter or early spring. Cultivation is easy, and growth can be tamed.

This Bordelon ornamental banana was first discovered in the Zone 8b Louisiana town of Bordelonville (near Alexandria). The 10-15' tall stalks are adorned with red-striped leaves that also feature an attractive red leaf back which is especially visible when the leaves unfurl. Based on trials around the country, M. Bordelon appears to be the hardiest of the red-striped varieties. If the growing point is protected in winter, M. Bordelon will flower and fruit, although fruits are seeded .
