This plant is truly a Brazilian Bombshell which is my name for it. I have had it for over 10 years and every year in late winter I enjoy the apricot-reddish tubular flowers of this stunner. I imagine the hummingbirds having a nectar feast. I give it a rest in November and leave it in my cool sunny west windowsill. By January the new growth appears and I begin to water again. As it is a tuberous plants it should be dormant some part of the year as it is in the wilds of Brazil nourishing itself from its tuber. I grow my raised to accentuate the caudex-like tuber. The inforescence is thick and silvery,as soft as the finest mohair.
