I am SO happy to have finally got my hands on one of these exotic lovelies after a long search- they're super hard to obtain down here. The 20cm high one I was sent was growing crooked, but I potted it up a little deeper to correct the angle and it hasn't looked back since, having rooted well in it's new position. Was lightly bronzed by the crazy early spring heat that came on this season but now gone back to mid green as the cloudy Jan summer has cut the UV levels drastically.

Not sure what sort of chemicals are in this plant- seems unusual though and probably has some 'use'- just need someone to figure out a use for it.

Flowers are profuse, branched and a bright red in mid winter. Seedlings germinate well in heat and humidity, and appreciate lots of water and humidity first year... then need to back off a bit on both or will rot. Once established at year of age in pot, become much more drought tolerant but still I would water more... read more
