African Gardenia (Mitriostigma axillare) - 2 to 3 feet tall, An easy-to-grow relative of gardenia that blooms reliably in the home, blooming almost continuously all year long with no extra effort. It bears small, star-shaped flowers that are pink in bud and open creamy white. The flowers are carried in clusters all up and down its stems and even the smallest stem will have a few flowers on it. There are dozens and dozens of flowers in bloom at any one time and their fragrance is wonderful, very similar to gardenia, albeit a little more subtle.
