There was a garden design competition held in March - 4 gardens were designed, then built in 24 hours (over a 4-day period).
The entire thing was documented on film; editing gave it a "reality TV" feel.
See www.tucsonbotanical.org/events/growdown/ for info on tonight's designer forum and film screening.
The film will soon be available on DVD for purchase.
I'll try to remember to post something here when the trailer is up on YouTube. It's a great documentary!
Peace to all!
