What is this flower with purple and white petals that roll up to form a tube?

Question

I found this very cool looking flower but have not been able to identify it. If you know what it is called please post your answer. Thanks.

Answer 1

I think that's an osteospermum whirligig, also commonly known as African Daisy or African Cape Daisy.

It's a perennial in USDA Zones 10 or 11, and sub-tropical regions, and is a long-blooming annual in cooler climates. It's shrub-like in shape, low-growing, and measures 8" to 12" high and 12" wide at maturity. Very versatile, it's a great garden bed or border plant, will trail over a rock wall, and also grows well in containers. It prefers sun and well-drained soil, but is very adaptable, making it easy to grow, even for beginners. Each of those unusual flowers lasts a long time, but dead-heading them encourages faster, more profuse growth.
