Thanks Sundra,
The Purslane overwintered really well and the 2nd year growth is much superior to the 1st year growth. It's dense and gets loaded with blooms. I was hoping Portulaca would overwinter since it's a similar plant. The white is like an uber white. Or maybe day-glo white! This family always has super bright colors and that apparently includes white. The orange blooms, on the other hand, are about the quietest color I've seen in a Portulaca. Odd, isn't it, that the screaming color is the white and not the orange?
