82ft? Good lord. What must that be like when they come crashing down. 

Likely would not make the homeowner's insurance company happy.

One leaf would fill up my green waste bin very quickly!

Solid zone 9, I can expect at least one night in the mid to low twenties every year.

Hot, dry summers. Cold, wet winters.

The Raphia Farinifera is almost as big, and is sort-of-available in cultivation.  It's a little smaller, only 20 meter fronds = 165 feet diameter!!!  It's hard to grasp just how big a Farinifera or Regalis would be.  A full grown Farinifera would cover 13250 square feet, 1/3 of an acre in space, or about 5 average houses.  A Regalis covers over 21,000 square feet, basically 1/2 acre or 8.5 average houses in the US.  

Farinifera is possibly 9b cold hardy, I'm kinda glad that I live at the 9a/9b border so I'm not too tempted to try to grow one.  :D  The plus side is that the fronds are persistent and not self-cleaning, so you can choose when the frond will come crashing down and destroy your car, house or wide swathes of your landscape!

They've got a good sized one of these at the Dallas World Aquarium in the greenhouse that's pushing 60ft I'd say

Thank you Trent! I know this vendor and have bought a few things from him in the past - he has nice selections most of the time.

Thank you!
