Osteospermum ‘Astra Purple Spoon’ – An early flowering variety with eye-catching blooms made of well-separated purple spoon-shaped petals and a bluish eye, from May through to October. Osteospermum are South African natives and are considered annuals or summer flowers in regions colder than zone 9. ‘Astra Purple Spoon’ grows 12-18″ high. Zone 9.
Osteospermum ‘Astra White Imp’ – A compact Osteospermum with white flowers (with a whisper of violet) contrasted by a bluish eye and a purple reverse.

Hardy to zone 9.
