Echinocereus rigidissimus var. rubispinus

"RUBY RAINBOW"

Mexico
"Northern Sonora, North-Western Chihuahua"

I like the look of this cactus, the spine coloration is very pretty. If I allowed this plant to have more sun, the spines would develop into a deep raspberry color. It is not one of the easiest of cactus to grow due to them being so prone to root rot from over-watering. One of the most interesting facts about this cactus is that it will take temperatures in the teens for a short period. No central spine is on the areole. Prefers soil poor in lime and usually acidic. Beautiful bright pinkish-red or magenta or red flowers with white throats are huge, up to 4" wide. Blooms in ring on the crown of the stem in spring. This plant is in a 3" pot.
