I will agree that the color of this low groundcover is very nice. However, once established, it became invasive in my garden, spreading rapidly and overrunning the beds.

Additionally, it seeds by putting up hundreds of slender stems with a spherical seed pod on top. When that seed pod dries, it will stick to anything and everything, your shoes, socks, pants, gloves. And of course, it's sticking to animals too and thereby spreading to other parts of your garden and to your neighbors as well.

This makes a great low ground cover with an attractie color. It spreads quickly by rhizomes, so be careful - it can become invasive if you don't control it's spread.
