Yes, it's the temps that make the color chages.
tarev, your blooming noid is one of my favorite plants, Calandrinia spectabilis, aka Rock Purslane. It's happiest in the ground and makes a nice spreading plant. Frost takes it down each winter but it always comes back and the blooms are so lovely nodding in the breeze.
