After a visit to the Cactus Garden at the Ethel M Chocolate Factory, this is one of the plants I want to have growing in my yard. I don’t know what it is, or how moisture-tolerant it is, but wouldn’t a front yard full of these make for a wonderful Halloween trick-or-treat experience?
Sadly, the “factory tour” doesn’t necessarily include having the factory be operational; it appears that it’s currently a Monday through Thursday thing, so if you see it advertised as part of a Hoover Dam or Lake Mead package, understand that you may just see a shut-down food line, without oompa-loompas or chocolate rivers. Go anyway, if you have any interest in cacti or special prices on chocolates.
(the other must-have from the garden is what I can only refer to as a “balloon-animal cactus”)
