Re: Aroids growing better in water?

From: "Kathy Kempf" wont_read101 at hotmail.com> on 2002.06.06 at 15:50:33(8962) Steve, as a former AZ resident, and outdoor lover and explorer, I encountered many cacti and other succulents that grew in standing water. Among the types I have seen growing this way were: organ pipe cactus (Stenocereus thurberi) in or around the National Monument, a grandma cactus (probably a species of Garambullo), and an unidentified type of cholla. All were grounded in the shore, but I could see many of the roots penetrating into surrounding permanent water (lake, pond, etc) and the flood-plain in which they grew made it obvious that the plant was periodically flooded, which would last for at least a week. Haven't tried to grow any of cactus this way, but they do grow that way naturally.
