I germinated a pair of Sabal Bermudana seeds about one month ago (first pic is from May 1) and sowed then after and have had them covered to keep moisture in and on a heat mat. Still haven’t seen anything pop up above surface of soil yet and I’m wondering if they might be dead or are just really slow 

I finally purchased the Beccariophoenix Alfredii here in Orlando Fl. I can’t wait to see how this beautiful palm responds in zone 9b.

this man in Sibley Iowa (Zone 4) grew a Washingtonia to 20 feet tall by building a greenhouse over it in the winter time. Unfortunately he cut it down but still has a smaller second one

I am looking for seeds of Sabal x brazoriensis. These used to be available here in Europe some years ago but they have been increaslingly hard to find.
Therefore, I'd love to buy some seeds if anybody has them. I am in Switzerland and have received seeds from the US many times without a problem.
Thanks!
