I live in the Puget Sound Region of Western Washington and this plant is not native to the area because it's leaves hold water when it rains and the branches break every winter so it's obviously not made for a rainy coastal or marine area. it has a large trunk and it splits off into branches at 5 ft. and the branches spread 10 ft straight away from the trunk, it is thickly covered by very large spade shaped leaves and it is almost an umbrella shape but grows up to 60 ft. high. it flowers every year in the late spring (see photos attached) and towards the end of summer it grows strange pods that look like very large green beans and can be as large as 16 in. or more. I would guess that it is from the southeastern United States Georgia, the Carolinas, bayou country. but don't put too much faith in that I am not by any means a botanist.
