Yes, it is vitex agnus, aka chaste tree or monk's pepper. Fantastic tree, just don't plant near a pool.

The seeds (peppers) are edible and the flowers attract butterflys.

That's a nice looking tree, might have to look into one.

A friend has one, she is always digging up seedlings that grow in abundnce. Not a problem if you pull them while small.

....or don't have a wet spot for the seeds to fall into and germinate. Of course, there's always monsoons to make your yard a wet spot....

My yard is irrigated so I have seedlings pop up here and there, but I wouldn't say there's an "abundance" of them. Oddly, they almost always pop up in pots.

... where you water more often, perhaps?

Probably, but I've had them come up in the driveway, so I really have no proof. On the other hand, it seems every d****d palm seed that a bird poops comes up wherever it lands. I am so sick of pulling those things up, I could spit.

Hey now, no spitting. Swearing and throwing things is fine, but spitting is just ... too much.

Well, it cursing is what you'd rather, come on over! I'm in the jungle, trying to tear out renegade lantana. Found some new words...

Have a weed whacker, will travel!
