Cephalocereus senilis
White hairy cactus about 35 cm tall with red flowers. "It is a tall columnar species with clusters of stems, growing to 5–15 m tall; the individual stems are usually unbranched, being unable to withstand the weight of side branches easily. The most striking feature is the long, white hairs it possesses, which serve to protect it from the sun. The coat of hair makes many plants appear almost snow-white (however, the hairs conceal numerous sharp yellow spines). At the young stage the cactus has silvery-white hairs, which are later lost as the plant grows." - Wikipedia
Balboa Park among other cacti and succulents. It is "native to Guanajuato and Hidalgo in eastern Mexico. It is threatened in the wild, but widespread propagation and popularity in cultivation have reduced the demand on wild populations." - Wikipedia
I think so too! I've seen some with a little of the white "hair" but never this much.
