Beautiful tree from a distance and very fast growing. Drops huge amounts of debris, especially following flowering, including large twigs attached to bifurcated leaf, flowers and small pods. They grow extremely rapidly in the semi-tropics and produce thousands of seeds which grow outside the canopy. Loved by birds and bees for nesting and presents a beautiful image unless you have to clean up gutters, decks or lawns. Will bring even ardent tree lovers to despair! Have posted a picture of a 7.7m (25') long perfectly straight grained log of 800mm (31") diameter. I am having it slabbed for use as several very large tables. Best decision I ever made, although I lost a few birds as a result.

While these trees are fast growing, dramatic looking and beautiful during their short flowering season, they should never be planted close to buildings as their roots are massive and intrusive and can seriously damage foundations and sewer lines. Also, they are very messy and require a lot of raking and sweeping, and are very prone to clogging house gutters and drainpipes with their litter. They drop a lot of sap which can damage the finish on cars. In my opinion, they work best in public parks and gardens

Grows like crazy in the east county of San Diego! Grew about 3 feet in a couple of months.

I live in St. Pete, FL and was amazed at the gigantic peltiphorums. I noticed them of course when they bloomed recently. I found them at the 2nd nursery I went to and they were quite inexpensive specimens standing about 10 ft. I stuck them in the ground with some potting soil in the blazing sun. They lost a couple of leaves and looked a little stressed for only about a week. Now they look happier then my year old poinciana! HARDY!

A wonderful landscape tree one sees frequently on the central and south Florida coasts but very hard to find at a nursery. Once established it is not at all picky as to water requirements withstanding heavy rains or weeks without equally well. Very showy when blooming and just as nice when not. Light and graceful.

This tree seems to grow well in the St. Petersburg, Florida area. I have seen many around town. There is an enormous specimen a couple of miles from my house.
