Found it growing in my herb garden.
by Robin Shope
It has a purple stem and green leaves with tiny yellow flowers in the center of the leaf cluster.

Hi Robin, I'm pretty sure this is Portulaca oleracea, sometimes known as Purslane. It's called a weed, but it can be trouble, as each leaf or portion of stem can re-root to continue living. The best revenge for it is to cook it and eat it - in Mexico it's called 'verdolaga' and the French know it as 'pourpiere'.
There are several varieties grown for this purpose, but Portulaca is mostly known as a pretty annual with bright pink, yellow or white flowers in hot dry sites.
