We saw this plant at a nursery in Carmel Valley, Ca, and my wife just had to have it. Except for the flowers, it doesn't look like a member of the Mallow family, but it is. Some research on the internet indicates that folks in Australia and Tasmania have found it to tolerate frosts down to -5C (23F), hence Zone 9.

Flowers are creamy yellow and tulip-shaped, with a red inner part and a "spinner" pattern at the inside base. Individual flowers last 2-3 days. The plant is an upright, airy bush with needle-like leaves. My research shows that it needs a low-phosphorus diet and little to no watering (it's a desert plant in its native habitat), so treat it basically the same as a Protea. I'll be watching mine with interest to see how it copes with our upcoming rainy season.
