A seasons growth
on my Pilosocereus pachycladus
Covering a wide range from the West Indies to Mexico and down to northern South America, Pilosocereus is a Genus of generally large columnar cacti. Some may reach a height of 30 feet or more and generally branch at the base rather than along the stems, though some take on a more candelabra appearance. Most have wool around the areoles and along the ribs and develop a cephalium along one side of the stems where the flowers are produced. Many develop a beautiful powdery blue bloom on the stems which can be easily marred if mishandled.
These make beautiful landscape plants but need to be protected from frost. I've had no problems with my P. pachycladus, they've come through the winter just fine, but a group of P. tillianus I had in the garden had their stem tips damaged. In pots use a standard fast draining cacti mix and fertilize once a month with half strength tomatoe type fertilizer through spring and summer. They can be propagated from stem cutting or seeds, but few would be willing to take a tip off one of these gorgeous plants unless trying to salvadge them from damage. Best to buy good size specimens at a nursery. Pilosocereus produce flowers similar to other ceroids in that they are usually white or pastel colored and nocturnal. All of mine are probably too small to flower but Trent, a fellow Daves Garden member, has a wonderfull picture he has given me permission to use. Thank you Trent! Click the thumbnail below to see it.
