I am pretty sure they are Filibusta as I...Read More have read pure Robusta are harder to find now, but they do have the reddish coloration on the stem like a robusta so not Filifera.They germinated in 7 days in a glass of water, their growth is very fast for a palm and they are already approaching 1 1/2 feet in 3 months with a little trunk already, and 3 leaves.They are growing like this even in winter grown only under shop lights with lower heat. In sunlight with more heat, the growth rate would be even faster and I can't wait to see what they do this next summer. My plan is to grow them in containers and put them out each year by planting the pots in the ground for stability, then lifting them and storing in our unheated shop that stays around 20F in winter by insulating the pots with blankets. You would be surprised at how much covering plants with blankets can help at ground level, I overwinter tropicals in an unheated polytunnel this way every year by laying down the taller ones and covering, with lows outside down to 0F. It usually stays about 35/40 under the coverings. Eventually if they survive, weight, or height will prevent them being stored anymore, and I will then plant them in the ground with a wrapping of burlap. Survival then would be very iffy even with protection as we can get down to 0F here once a year, and we usually go below 10F at least 3 times.

This particular plant I have is 6 feet tall 4 1/2 trunk feet and has frond color of Robusta (green green not olive green) and frond shape of Filifera and has had only minor damage at 14F. Our winters here are our wet season and tolerates this fairly well and grows back quite well in the summer with the dry season and the low humidity.
Washingtonia FiliBusta hybrid grows here without protection and is completely defoliated (browned) but grows back in spring and it starts...Read More growing as early as February, but it may get in trouble or even be killed on colder winters. I have one dead, but I suspect it may have been killed by voles?
Will try W. filifera from now on, probably a good one for this area too as long as its kept in a well draining soil.
If anyone in mid SC has flifera growing in ground successfully I'd like to see if possible. I know only one W. filifera (or is it a hybrid?), which is very large and grows right next to Hwy 378 which is a Sunset Boulevard between Columbia and Lexington, SC.
I think SC needs plenty of Wash. Filiferas as they should do well here and would beautify the place much.
UPDATE: I wish everyone would describe hardiness of a plant in several stages: while a seedling, while a young plant, a larger plant but still without much trunk and then an adult plant. This same palm as a small 1 footer can get damaged by temperatures that are much warmer than 15F. Make it a new default standard and lots of new research.
Some plants while small can get killed by 32F or below (or above), yet some can withstand down to 20F more or less as seedlings. This kind of research and info is important to provide along hardiness for adults palms. Giving hardiness info (USDA zones and temperatures) just for adult plants is not enough to get the entire picture.
Mine as seedlings in a community box outdoors got exposed to 20F and a lot of them survived just fine the winter of 2012-2013.
Yet the winter of 2013-2014 is another story - temps went down to 12F and a lot of palms in all kinds of sizes got damaged,
2014 UPDATE: My W. filibusta hybrid with ~1 1/2 ft. trunk in a 45 gallon pot survived (central spear and some fronds are a bit green at the very center with the spear NOT pulling, which gives hope) all winter outdoors while the 12 ft. OA W. robustas all seem to be dead.

Perhaps the same reason that a peice of toast always lands on the floor jam-side down; landing jam-side up only when a dog is nearby to eat it before one can retreive it.
