Native to China, Hypericum chinense is unique and beautiful yellow flower, which blooms in summer (May to July). The sweet-scented blossoms sit atop two foot stems that rise from low-growing foliage. The blossoms are abundant and brilliant, and create a striking display. The petals have a crinkled silk appearance, and come in shades of yellow and orange. Most are single forms, but semi-doubles are sometimes seen.
