Unknown flowering tree...

[Mandrew968]

This tree is on the outside of our fence--outer perimeter of the garden. I have never paid attention to it until it got these great big yellow rose looking flowers. Very pretty... no leaves right now, which should be a clue... If anyone could help with an ID, I would be very grateful--thanks in advance!

For some odd reason my uploads are failing...

Taking a guess, based upon a few cues in your description: First thing that came to mind was Buttercup Tree (Cochlospermum vitifolium).. "Florepleno" if the flowers are double instead of single-petaled.

You are on the money. Thanks. the flowers are double. Love your avatar. Are these trees common?

Figured you'd appreciate it 

As far as Cochlospermum, can't say for certain but the only tree i personally saw was near the entrance of Redland, and possibly another in a yard near Krome and 264th. As difficult as it has been trying to find either seed or small plants of both the single or double flowered variety, id assume they're still a rare find. Thinking you can start them from cuttings, but not 100% certain.

I gave Adam from Loxahatchee a 12 foot cutting of the double flower last year.  It rooted just fine and flowered this year.

Good to know Jerry. You know of any U.S. sources for seeds?.

Don't know where to get seeds.

[Mandrew968]

Good to know! They should root from smaller cuttings than that, no?

Do you think they'll grow here in California? Or assist tree tropical and its requirements. The flower this tree boasts is amazing!

[Jerry@TreeZoo]

The weather never tests them here so I have no idea how they would grow in the upside down California climate.

The double-flowered variety can only be propagated from cuttings or grafting.  The single flowered variety can be grown from seeds and there are several species of Cochlospermum.   They have Bixaceae-like flowers (when single) with Bombacaceae-like fruits/seed pods.   The wood is a bright orange-yellow throughout.

I'm sure they will root from smaller cuttings also, but better take with larger. Larger meaning a branch piece vs a tip cutting.  It's a stick-it-in-the-ground (or pot) type thing, not in cup of water or mist bench.  My experience growing most tropical trees from cuttings has worked better with larger (Ceiba, Bombax, Pseudobombax, Bursera, Gliricidia)  .  There's just more life juice in the cutting to sustain itself and push out callus and eventually new roots.

Here is a pic of the cutting I planted, thanks to Jerry
