Couple years ago I put up some seeds for germinating,after a year nothing happened on a few different seed varieties,so I thru my soil back in with the rest of the compost pile,then 2 years during the summer I had these 2 come up,only palms that I can remember off hand were either Rhopalostylis sapida,Satakentia liukiensis or Kentiopsis oliviformis ,these are a couple year old seedlings now,anyone have a clue to the Id?
Lots of palms at that size are very difficult to identify. Those in fact look very similar to my Calyptrocalyx elegens at that size. But they probably look similar to a lot of other species as well. You might have to wait a few more years for a definite answer.
Always difficult when you don't know what a plant is. You might be doing things to slow it down, or maybe things that are speeding it up. You never know. I collected a lot of Adonidia merrillii (Christmas Palm) seeds from under the tree. Only 3 came up, really fast. Now I think the others may have been cooked by the sun, they should have been up by now. But the seedlings seem to have stopped growing, despite being the middle of our summer. Often a palm will break the surface to start photosynthesising and then devote all its energy to developing a deep root system. They can sit there for years apparently doing nothing. Then suddenly they put on a burst of growth. I think palms are more prone to that than other types of plants. Good luck with them.
