Otatea acuminata aztecorum (Mexican Weeping Bamboo) - A gracefully-arching clump bamboo that can reach a maximum height of 20 feet. The canes can grow to a diameter of 1 1/2 inches and are densely clothed with very thin, narrow and long light green leaves lending the plant a soft appearance. Somewhat drought tolerant once established, at least in coastal gardens, but looks best with regular to occasional irrigation. Hardy to 22F and even lower for short durations (took 18° F in 1990 freeze without damage). This bamboo is native to Sonora, Chihuahua, Sinaloa, Durango, Nayarut, Jalisco, Michoácan and Guerrero provinces of Mexico. It was introduced into the U.S. from central western Mexico around 1958 by the L.A. Arboretum. San Diego plantsman Bill Teague received a division of it from the Arboretum in 1966 and began propagating it and then distributing it to fellow collectors and nurserymen throughout southern California. We first began growing this plant in 1982 as Yushania aztecorum. These plants flowered in the early 1990's, producing viable seed that produced the plants now in cultivation. According to The Plant List, the collaborative database of the Royal Botanic Gardens, Kew and Missouri Botanical Garden the plant listed as Otatea acuminata ssp. aztecorum is now correctly back to being called Otatea aztecorum.  The information on this page is based on the research that we have conducted about this plant in the San Marcos Growers library, from what we have found on reliable online sources, as well as from observations made of our crops of this plant growing in the nursery and of plants growing in the nursery's garden and those in other gardens where we may have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Otatea acuminata ssp. aztecorum.
