good locations

Potential living space locations include; East, West or South windows and three to four season rooms are good, but it will grow better outdoors. Please provide winter conditions below freezing for this plant, otherwise it will never bloom. This is a very cold climate cactus and will survive winters down to -30 °F. This variety is going to grow better and bloom if it is planted in an outdoor rock garden between zones 7 to 2, and really should be kept outdoors.

The range of their native habitat covers most of the Northern Rocky Mountain western states at high altitudes. For all subspecies of Echinocereus virdiflorus their habitat also extends into the southern rocky mountain states and the planes of Kansas, Oklahoma and Texas These plants and their flowers vary in appearance, and are divided into numerous subspecies. They tend to grow as small singular stemmed plants rarely more than two inches thick, but older plants may produce offsets.

They have small flowers, but with some of the most interesting colors among Echinocereus cacti species. Their flower colors range from rusty oranges, browns, greens and chartreuse. A few versions of this cactus have lemon scented flowers, but most are scentless at least to humans.

They often grow in sparsely wooded areas visually blending in with grass, which makes them very hard to see at first glance. Short new spines often grow in rusty red colors and their spiny visual texture varies for each plant as well as for colonies in habitat locations. These plants survive some of the coldest extreme high altitude climates the rocky mountains have to offer. They are able to grow in rocky soils where day and night time temperatures widely vary. They are a very impressive example of a cacti which survives extreme conditions.


These cacti can grow to little more than a few inches wide and up to 4 inches high on the main stem, and any offsets will remain smaller than the first stem. Some plants will make a few offsets when they are older, but many will simply remain single stem plants for their entire life span.


This species grows at high altitudes in Colorado and New Mexico.
