Gardeners' Notes:

Peanut cactus and some of the cultivars of such are hardy here to the mid teens but need some shade from our intense sun here at 3000ft.

Neutral Xenomorf On Jul 29, 2007, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

The flowers are red-orange and red. This plant is often mistaken for Echinopsis silvestrii because of the recent taxonomic changes.

Positive palmbob On Nov 27, 2006, palmbob from Acton, CA (Zone 8b) wrote:

Common small cactus with finger-like columns and red flowers, often produced in prolific quantities. As cactus ages, eventually columns droop over landscapte- looks great in pots, but can be a bit messy in a garden- somewhat prone to rot, then, too. Older columns eventually become woody and spineless.
