I thought some people here might be interested in some of the research that is done on palms , in my lab we are working with Cocos nucifera and are trying to develop different methods for ex-situ conservation such as in vitro culture, cryopreservation. And recently we developed a protocol which allows the micropropagation on the coconut palm. This allows us to safely store these palms in in vitro genebanks but also use the material for cryopreservation or to replant coconuts on the field. On the pictures you can see the multiple shoots which are all clones.
What is your opinion on using these techniques for safeguarding palms?

Out of all the coconut varieties in the world, which one would you say can handle cool temps for the longest?
By Yunder Wækraus
A month ago I purchased a young coconut that had been grown in a grocery bag. It had terrible root wrap, and I had to sever its thicker roots, which had fused with the bag. It looked yellow and sick, but it’s putting out a new frond now. Do you think it’s going to grow out of the root-wrap stage? (I’m also including pics of my other palms, which came with the house.)
Cyrtostachys renda, the Red Sealing Wax Palm (also known as the Lipstick Palm) , has the well-deserved reputation of not being able to grow 'en la tierra' in Southern Florida. Notoriously cold-sensitive,
It can 'brown off' at 40 degrees F. Attached photograph shows a 10-year old plant doing quite well on Miami Beach. It has a western and southern exposure and is shielded from the north. There are two 'tall' trunks , reaching 10 feet (highest point). The palm has managed 46 degrees F with no damage. On the same evening, temperatures 1-2 miles inland (Coral Gables) were 42 degrees. South Florida has had a long streak (?15+ years) of mild winters. I can testify to knowing of fruiting breadfruit trees 25 feet high a mile from Biscayne Bay (something unthinkable 30 years ago), anecdotal evidence of climate change. Are other enthusiasts having success with the stunning Red Sealing Wax palm in Miami and environs? Just curious.
So a little over two years ago I was on Maui and was able to get a sprouted coconut (about 2 inches) back to my home in Montana. Last spring it grew large enough to hit my ceiling. I had a large LED grow light over it but once it grew large enough, it just shot fronds past it. Admitting it was likely the end, I put it outside during the summer. It survived, despite some of the fronds dried out from Montana's very dry climate near the mountains. However, its growth greatly slowed and I was able to bring it back in during the fall. Well, as summer approaches, the coconut palm is still alive. So basically, how long can I slow its growth without killing it?
