The beautiful and glorious osteospermum is a member of the Calenduleae genus of flowering plants and is related to the sunflower and daisy family. Osteospermum plants are often used in summer beddings because of their bright colours and propensity to bloom all summer. eBay has a large variety of osteospermums available on site from top sellers. These come in new condition as either full-sized plants or seeds you can cultivate yourself. Many plant sellers offer free shipping with purchase, so you can get several coordinating colours to plant together, such as Pink Whirls, Sunkist, Silver Sparkler, Pink Beauty, Nairobi Purple, and Buttermilk.
