This is a low grower and the only thing I can come up with is a Whipple Cholla. But this is so low growing. We saw a few of these plants. https://www.americansouthwest.net/plant ... pplei.html The usual form of cylindropuntia whipplei is an upright shrub, 6 feet or more high, with many 3 to 6 inch stems branching from a woody central trunk, though the plant also has a low growth variant, found in less favorable environments, where the stems are shorter, stay close to the ground and may have fewer spines. Stems are bright green or sometimes purplish green, bearing distinct tubercles and clusters of 3 to 8 white or yellowish spines, each between 1 and 2 inches long. The spines do not completely cover the stems.

Whipple cholla is very frost tolerant, found at higher elevations (8,000 feet) and further north than other species.
