I planted this Mimosa tree about 3 years ago, and this is it's first blooming.
My grandmother warned me that these trees could become invasive. I didn't know about the seeds being viable for so long though! Oh well. I guess I can pull up the seedlings as they germinate. It is too pretty a tree to get rid of.

You'll have to watch this tree after a few years as the seeds inside the seedpods it produce can be viable in the ground for nearly a century! Their hard waxy coatings keep them preserved until scratched to allow moisure to pentrate. If you have to mow around this tree, inevitably you'll be scratching a number of these seeds as the lawn mower rolls over them and they will sprout, sometimes lots of them!
