Sabal species ID

[Jesse]

I have planted a Sabal in my garden without knowing the species.  If possible, does anybody know? I know it's not mature yet but am curious what I should expect. Possibly minor?

Any help is appreciated. TIA

I don't think it is a S. minor. It could be any of the other species, but my guess (based on my own observations) is Sabal causiarum. Whatever it turns out to be, the colors are gorgeous!

I'm not too sure, but it could be a S. bermudana - which has a prominent yellow patch, around the hastula.  It's pretty commonly cultivated, too.  But, I believe other Sabals have that feature, so some degree.

Thanks you two!  This helps me narrow it down.  I was told that the seed was from a Sabal in San Diego from either San Diego Botanical Garden or Balboa Park according to my memory.

S. Minor or S. Bermudana is what I would say as well. Looks good!

Here are my 2 c: Does not look to me like minor because it has already a hastula on the way to becoming prominent and many filaments among segments, which exactly is what minor lacks of. Seegments look halfway down to the midrib sepatated from each other, which excludes palmetto. Margins of hastula look not enough involute, which would otherwise distinguish bermudana (at least on several specimens growing in Europe). On the other hand a causiarum growing in  Ca is often prone to potassium deficiency, which here is not the case, plus causiarum has long ligules among leafbases, but latter may develop later.  Such a deficiencymay may show up later as well though, when the plant grows bigger and needs of potassium increase (although Steve Toad has a  very well nutritioned causiarum). The closely related S domingegsis has very rigid leaves almost cardboard like in texture. Here are some simple rules of identification you should have in mind as the specimen grows older and bigger and resumes its final appearance.

How fast is this sabal growing?

[Jesse]

I would say moderate growth. Since planting it on Oct 22nd last year it has probably pushed about 5 new leafs, or more. Here it was after planting.  I apologize for the poorly composed picture as Sabal comparison was not my original objective.
