As stated by Palmbob, this plant is toxic because the sap is. And it's a very invasive weed... yes folks, it's not a tree, it's an arborescent weed, hence the viciousness... as a weed, it's not made of "wood", it's a useless tree (aside from shadow, which is quite important for cattle and houses, and is the only reason it is intentionally grown). The "wood" is spongy and soft, and you will be surprised to find no growth rings if you chop the plant down (again, it's not a tree, it's a herb). In fact, when cut to the ground, it will grow again and again right away... in fact, it will actually grow faster and stronger.

IT makes roots that crawl right under the surface about 2' thick and up to 50' long. Beware concrete, because this will lift you right up! But wow, what a tree! It does get a bit toasted by frosty winds in the winter, but grows back instantly. And the leaves are so huge and green they add a great tropical look to the garden. And the shade... read more
