We grow two climbing members of the genus: Kennedia coccinea and K. nigricans, both rampant and aggressive climbers. The latter specially can grow 4 meters high , or more, in one season. It is in bloom right now, and will go on until April; the flowers are very exotic but not really showy, being jet black with a yellow tongue they sort of disappear among the foliage; anyhow they are very attractive and piece of entertaiment for visitors, who marvel at its blackness.
The coccinea , on the other hand, is really showy and the red flowers are beautifully enhanced by the fresh green foliage.
Never tried the prostrata. but it looks very interesting, worrth trying!
