how tall and thick does Caryota obtusa get in south Florida sandy soil?

[miamicuse]

Bought this 4 years ago at a palm sale event at Mounts, labeled Caryota obtusa. Is this identical to Caryota urens or gigas? I haven't planted this into the ground yet because after reading about these reaching 60' and warnings that these can really get super wide and thick...Any idea how big these gets in full sun conditions in south Florida (sandy soil) and if I have a spot 20' from a house if that's OK to plant or not?

Any idea of it's growth rate?  Is it faster or slower than the typical Caryota mitis?

Since this is a solitary palm, once it flowers it's gone, unlike Caryota mitis being clustering the new younger stems replace the old ones?

I believe Gigas is a synonym for for Obtusa. My soil is central Florida sugar sand, and I didn’t amend enough when planting mine. Read some advice about using black cow around it after about 4 months of no growth and yellowing fronds. Couple of bags of Black cow spread around the drip line greened it up and got it to grow. Even then, only 3 fronds in two years, but probably due to not enough sun. Likes a lot of water too.

I’m not sure about your area but here in Southern California they get huge. C. Obtusa is much wider than C. Urens . Mine isn’t nearly as tall as the Urens I planted at the same time. But each new frond is huge . Harry

‘The palm to the right of the gate is C. Obtusa (C. Gigas when it was planted). To the left are the trunks of two C. Urens , one large and one small.

This shows the difference in frond size . The tall one in the middle is C. Urens and to the right , and not near as tall as, is the C. Obtusa. Yes , both want lots of water !
