Description: Nowadays Echinocereus plomosusSN|7070]]SN|15744]] is considered none other than a form of the very variable species, Echinocereus polyacanthusSN|15744]]SN|7070]].
It is a highly branching plant that forms large clumps and blooms abundantly, just as a small specimen .
Stems: Light green, cylindrical, tapering towards the tip, each stem 10-20 cm tall, 4-5 cm in diameter.
Ribs: 9 to 13, usually 10 well defined ones, low, either tuberculate or not.
Areoles: Approximately 1-1.5 cm apart, and somewhat woolly.
Central spines: 1 to 7, yellowish or brown, expanded basally, straight, elongated, becoming grey as they age, reaching up to 5 cm long, but variable in length.
Radial spines: 6 to 17 (usually about 12), dirty white to brownish, overlapping, up to 1 cm long but often much shorter.
Flowers: Diurnal, arising near the stem's apex, tubular to funnel-form, brilliant deep red with a yellowish or whitish colored throat, 10 cm long, 5-6 cm in diameter. Floral remains are difficult to detach from the plant and can set up stem rot.
Blooming season: Apr-Jun, the flowers remain open for 2 or 3 days. Blooming generally begins 4 to 5 years after sowing, as the plant matures.

Cultivation and Propagation: This cactus is cultivated and highly priced for its flowers. It is among the easiest species to grow, flower and propagate. Water regularly from March to October. Rot prone in winter, it needs good drainage. Claret Cups require strong sunlight to maintain a healthy appearance, and a harsh "dry and cool" winter environment combined with maximum light exposure enhances spring flower production. Frost Tolerance: Hardy to -5° C.
Propagation: Seeds (usually), it also can be grown from cuttings, as it branches profusely from the base.
