Rothmannia capensis is one of our most beautiful evergreen indigenous trees. It has a dense, roundish crown of glossy, dark green leaves. The flowers are large, white to cream bells with maroon speckles in their throats. A tree in full flower is a sight to behold. The flowers fill the air with a wonderful ‘gardenia’ fragrance.
