They do produce female flowers (otherwise there would be no coconuts), but the inflorescence is spicate. We have some spicate varieties in Florida, with the most popular being "red spicata". Here's an image of one growing in Miami.

Thanks for the replies! My brother bought a tree yesterday based on one of these suggestions, so I'm gonna share some scionwood with him for the Cotton Candy.

Dr. Campbell talks about growing trees on a "super-dwarfing rootstock". I wonder when that'll be released to the public?

Also, I've talked to Mike Winterstein at the Miami germplasm about a dwarfing rootstock they're experimenting with called "creeper". I wonder if that's the one Dr. Campbell is using.

wow, that is good to know that it may not be superior to LZ.

I'd still like to buy seeds even if that is the case.

Since we're well into mango season and some people may be eating these fruit from the very few locations that do have fruit, does anyone have OS seed for sale?
