It will vary on species, but most will go pinnate by a large one gallon size.

I guess to a first time palm seed grower, those "immature" fronds on seedlings might make them question if they got the seeds they'd expected? I remember my one and only successful seed sprouting of some date palm seeds, yeilding some ribbed looking and almost crab grass looking fronds , when they first sprouted. Not terribly impressive, but within a year of so they did begin to feather out. I unfortunately parted with the plant once it reached my ceiling and I no longer wanted the expense of repotting it to those larger and larger pots as the roots grow so fast and thick. Now I miss it of course. My second attempt at some windmill seeds failed entirely, when all seeds rotted !!

I have know dought that it is a King. The fronds are certainly taking shape as far as the "branch" part go. They also seem to be doubling in size with each frond. Maybe by the end of next summer it will start to feather. I am getting exited about the size and shape it's taking.

Andy - here's a picture of one of my King palm seedlings. He sprouted in March 2006. I kept them in a protected area last summer (maybe 2-3 hours of morning sun). I expected faster growth. How does yours compare size wise to this one and how old is yours?

Andy:

They feather rather quickly. I have 2 Kings in the same pot that are about 3 years old and are completely feathered, and growing really fast. I'll take some pics tonight and post.

My earlier post, was meant for a first time palm seed grower and not to question the varieties pictured as to accuracy , but as mentioned, if you've not grown some before , you might find the odd look of immature leaves, as leading you to question what you planted, is all I meant. If I hadn't known for example that the soil used was devoid of weed and other types of seeds where I planted my date palm seeds, those first crab grass looking leaves that came up , might have made me question what I was looking at or perhaps some other type of plant even, though I did cheat a bit and dig down carefully from soil level at the leaves to see if indeed they met up with a palm seed, and not some other type of unintentional seed!! I noticed somewhere else that someone had started a data base of sorts of many types of plant seedling photos for identification purposes, should one question their plants for accuracy, or in the case they lost the name tags, and I guess such a thing might be helpful for identifying young palm seedlings in some cases. It's not unsual for me to plant other types of seeds, and sometimes have unexpected results if things were mislabeled etc.
