The fire-cracker cactus, Cleistocactus smaragdiflorus, is a shrubby cactus species at first erect, then crawling on the ground with long basally branching stems, up to 1.5 metres tall and 6 metres in spread. It greatly resembles Cleistocactus baumannii in size and appearance except that the spines are usually shorter and darker and the scarlet flowers are tipped with emerald green. Distinguished by the brilliant emerald green tip to its red flower, this free-blooming species is slimmer than Cleistocactus strausii, but not nearly so well known.

Soil: Grow it in a rich and particularly draining substratum, as it is very sensitive to rottenness when in presence of humidity and low temperatures and let the soil dry out between waterings.
Water: In summer, during the vegetative period, it must be regularly watered, but allowing the substratum to completely dry up before irrigating again; in winter, it�s to be kept dry. Preferable not to water on overcast days, humid days or cold winter days.
