Gardeners' Notes:


On Mar 20, 2016, coriaceous from ROSLINDALE, MA wrote:

The corolla is brilliant red, the calyx is pinkish purple and lasts much longer than the corolla.

More shade tolerant than most flowering climbers.

At the Fairchild Tropical Botanic Gardens in Coral Gables, FL, this was in spectacular bloom in late March. It was grown over a large pergola, but it had also spread far and wide by suckering. The upright suckers had been cut to 1-2' and formed a spectacularly flowering ground cover.

It has a reputation for producing suckers at a substantial distance from the first stem. It is a sterile hybrid and does not produce viable seeds. I'd be reluctant to plant this in the ground in a semitropical garden without a root barrier, because of the aggressive spreading, but this is not listed as an ecologically i... read more

I have this vine growing against my house, here in zone 8b. It is a huge vine and blooms constantly. I haven't been here during a heavy frost (just moved here), but this vine is beautifully and contentedly blooming it's heart out. I highly recommend this vine!

Stunning plant almost never out of flower here in Perth Western Australia (except in late winter - early spring). Good cut flower and looks fantastic with blue ginger (Dichorisandra thyrsiflora) underplanted. Have planted with stephanotis floribunda for scent. Do not find it invasive. Needs good soil and moderate water in dry season.Likes heat but prefers half day of sun or filtered sun in our hot climate (35-38C temps in summer).

This tropical vine has nice, large, deep green leaves, and pretty flowers. It is a sterile hybrid, which does not produce seeds.
It blooms from Spring until frost. It is not hardy for me in the ground, here in zone 8, so I usually over winter cuttings for the following season. It is easy to root, and easy to grow. It is also very resistant to disease, and bugs.

Brazil wrote:

A scandent shrub, with very showy bloom, obtained by the crossing of Clerodendron splendens and C. thomsoniae, with long stems and dark-green leaves. Inflorescence is a large, terminal cluster, with many red flowers, in showy light-red calyces which persist after blooms fade. Flowers are produced in spring and summer.

Usually trained against supports. Suitable for covering all kinds of fences and arches, in full sun. It is frost tender.
Propagated by cuttings, taken at the end of winter and rooted in protected site (such as a greenhouse.)
