For anyone who loved "Little Shop of Horrors," this enormous agave should remind you a little of "Audrey II." This would sure be a pretty effective security system, don't you think - just eat any trespassers!
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
