This South American suckering fan palm comes from Argentina and Uruguay. From these locations, you might suspect it could have quite a bit of cold hardiness, and this is the case with not only this species of Trithrinax,but of the genus as a whole. Availability of seeds of this species has been sparse to nonexistent. And, as a young plant, it is quite slow growing. Consequently, to get a good sized container plant can take a decade or more. We were fortunate to offer some very nice 5g plants as shown below. I’d estimate their age at 7 years. They are dividing and very chunky at the base. They are totally acclimated to full hot sun and are intensely blue. This is a perfect selection for someone who lives in an interior area with lots of heat.
Overall height of this species is up to twenty feet. Multiple stems are produced, but usually the number is just several. Leaves are small, typically about two feet wide. The segments of the leaves are pointed and sharp. Trunks retain old leaf bases but, like Washingtonia, eventually fall off. This is a drought tolerant species and can take temperatures well into the 100’s F. and cold tolerance is into the teens. Of note, most specimens I’ve seen are blue. The 5g size is shown in the first 5 photos. The last two photos show a mature plant that is blue-green in color, probably due to the fact that it’s not getting full sun.
