GIANT~Ensete Ventricosum~ EXOTIC Banana Tree - eBay (item 380028953318 end time May-23-08 08:30:24 PDT)
One of the nursery people here should have a few.
Worth just buying one as it's early season and they grow huge fast. A small plant will be 6 to 9 feet tall by the end of August.
Sandy here has some small Ensete Maurelii for only 6 bucks each plus shipping so worth getting a couple , I got two . I also got a decent size 'Maurelii' from Brian's Botanicals (Aroidgrower). Brian had Ensete ventricosum last year , I'm not sure about this year. I got my Ensete Superbum from Brian's ebay site.
