Additional comments: Yellow dot is a good ground cover choice for Phoenix landscapes with much greenery (you Arcadia residents will love this plant!). It is one of the few ground cover plants that can survive central Arizona desert combination of extreme heat and sun at ground level where it's sizzling during the summer.
