Multi trunk Phoenix ID
Saw an interesting multi trunk Phoenix today in Destin. Must be a hybrid of some kind. My guess is Phoenix Canariensis and Phoenix Roebelenii hybrid. What say you!
It was seeding too, so took a few and will try to germinate them.
Do Sabal Hybrids Happen Often In The Wild? Does Anyone Grow Sabal Hybrids?
Whenever I am somewhere where two Sabal species ranges intersect, I never seem to see any hybrids. For example, In South Carolina I will see Sabal palmetto with a bunch of Sabal minor at the base (and younger palmetto) but never see any hybrids. Do hybrids rarely happen? I would assume Sabals in habitats that intersected with one another would be a genetic mess, even though it is not really. Does anyone grow any Sabal hybrids or seen them happen? I am confused about the whole hybrid thing when it comes to palms. Sorry if this is a dumb question.
Encephalartos arenarius x woodii 7 years later
I was looking at the new flushes on my Encephalartos arenarius x woodii as they near there full size and realizing how much this cycad has grown since I planted it. I searched for photos of when I got the plant as a 15 gallon and found the one below pictured still in the pot. The photo was February 2011 and I planted it within weeks of the photo being taken. 7 years later one of the pups would dwarf the caudex of the original 15 gallon plant. The third pup is now flushing 5 leaves, while the larger pup has pushed somewhere in the high teens of new leaves. I'm optimistic that I'll actually live to see this be a large cycad at this rate. Chalk one up for hybrid vigor !
Germinating old Brahea seeds in less than 2 weeks?
it has been quite some time I posted something on Palmtalk, but now I am back and happy to see so much progress in your gardens!
Now the story:
In 2014 I received some Brahea sp. seeds from Phoenikakias, I tried them few times, but they didn't sprout and as the time passed I stopped trying and forgot that I still have some left. I rediscovered them them this April and got an idea to try "removing the lid" as I've read in topic posted by Cypalms and John in Andalucia (links bellow). And it really worked!
I removed pulp residue by sandpaper, soaked seeds for 2 minutes in 70% ethanol, then few more minutes in diluted bleach and placed in previously boiled distilled water for 2 days.
After soaking them for 2 days, I removed the area (operculum) above the embryo by scalpel to expose it. I tried to stay sterile as much as possible, to prevent bacteria/fungus contamination.
I placed prepared seeds in coco peat (also boiled for some time) so the embryos were a bit above the surface and placed them in incubator with constant temperature 30°C (86 F).
6 days later the embryo started to grow out:
Yesterday and today:
It really surprised me that even almost 4 years old seed of slow germinating species such as Brahea can sprout in less than two weeks using this technique, I encourage you to try it too!
I will try some other species such as Butia and see the results. I'll keep you updated!

Syagrus x costae ? ID assistance
I had the pleasure of visiting a fantastic palm garden in Brownsville, Texas (zone 10a) a year ago for a PSST meeting. There was a nice looking Syagrus dropping fruit at the time and I collected a few of them to germinate. There was no sign next to the palm and when the owner gave a tour, I asked him specifically about the palm and he only acknowledged that it was some Syagrus hybrid. I did a little research to try and identify it and believe that it is Syagrus x costae based on the appearance of the fruit and the commonness of the hybrid. (I am not good at identifying minor differences between species!) I'm posting a photo of the tree (I apologize for the poor quality as it was difficult to photograph among so many others) as well as a photo of the fruit.
