I absolutely love this plant. I have had it over 20 yrs and never grow tired of it.

It's October, the time of year when this plant becomes colorful and showy. Any other time, it simply appears to be an ordinary weed, which is the way most people treat it. It is toxic, all parts of it, but I've never seen a cat or dog try to nibble it. Its color is striking, low to the ground shades of red and pink, changing slowly to burgundy. A pretty plant.

Be careful where you plant this in zone 9b. I planted just one little plant - and I am pulling dozens of them out every time I weed. They are interesting plants, but would probably be best in a contained bed, or in a pot unless you really want lots of them. Those beds are partial/deep shade, and they are very happy.
