Pretty darn lush Gary! How far of a spread do you water a tree like this, that's planted out in the open?

That is pretty impressive. I would treat it exactly like Delonix Regis.

So many species,

so little time.

I have one in beach sand with no irrigation. it looks pretty thrifty, not nearly as pretty as yours, but it blooms every year since it was about 5 or 6 years old. I have another in really good soil that gets irrigation (from the neighbor) and it is big and green like yours but no blooms. Maybe this year? The one I have in beach sand is blooming now.

So, how do you treat Delonix regia? Summer water, no winter water?

I water from March to November then cut off the water completely in the winter.

Here for Delonix, if you give them no irrigation (after initial establishment) you get a very nice, intense bloom display for about 6 weeks in mid summer. If they are in an irrigated landscape the will bloom sporadically from April to November. Never a huge display at any one time but spread out over several months.

I have never seen Colvillea bloom any other time than the fall though. No matter if it is in an irrigated landscape or not. BUT, there are about 1000 Delonix for every Colvillea, so we really do not have as much experience or diversity of conditions and genetics to make too many generalized statements about Colvillea.

Good information Jerry. As there are very few Colvillea growing in Southern California, the experience is limited. As of yet there has never been one that bloomed out here. Mine is definately approaching blooming age, so it will just a matter of experimenting with it to see what sparks the blooming.
