Lophocereus schottii
Also called Whisker Cactus, Senita Cactus
Old Man Cactus (Lophocereus schottii) is a columnar, tree-shaped to shrub-like cactus from the Sonoran Desert of southern Arizona and northwest Mexico, known for its long white hair-like spines at the top. Grow it in full sun with very sparing water, as it tolerates desert heat well but rots in wet or cold soil.
Lophocereus schottii, the senita cactus, is a species of cactus from southern Arizona and north-western Mexico, particularly Baja California and Sonora.
Tetrahydroisoquinoline alkaloids were identified; one of them, lophocerine, is a substituted salsolinol, as well as a trimer of lophocerine—pilocereine. Among other compounds, phytosterols such as lophenol, schottenol, lathosterol, spinasterol, locereol, and other compounds. Salsolidine, peyonine, peyophorine and anhalotine were also isolated; among the flavonoids, myricetin, epicatechin, quercetin derivatives, and kaempferol were isolated.
The distribution area of Lophocereus schottii extends from the south of the US state of Arizona to the northwest of Mexico and includes the states of Baja California and Sonora. The species grows at altitudes from 0 to 800 meters.
