Description

Espostoa lanata (a.k.a. Peruvian Old Man Cactus ) is a slow growing tree shaped cactus branching at the top with age, 1,5 to 7 m tall. Like Cephalocereus senilisSN|6893]]SN|6893]] (the Old Man of Mexico) it is a densely hairy species, covered by a warm woolly coat and well adapted to high altitudes, the main difference is the presence of sharp spines on Espostoa. The crest form Espostoa lanta f. cristata - despite to its beauty - is still very rare and sought after by collectors, for its unique features.
