【产地及分布】：原产南美洲。It is found in open woodlands of Colombia（哥伦比亚）, Ecuador（厄瓜多尔）, and Peru（秘鲁）.
【形态特征】：常绿多年生蔓性灌木。The Marmalade Bush is an evergreen, perennial bush from South America. It has a spreading habit and can be allowed to spill over a wall or hanging planter, or pruned to a neat, upright shape. Even without blooms it's an attractive plant, with glossy, bright green foliage that has a ribbed appearance. The flowers appear almost all year long here in San Francisco, with the heaviest show from spring through autumn. The 5-petaled blooms start out yellow or light-orange when they first open, then deepen to a darker-orange and red as they mature. Butterflies and birds regularly visit the Marmalade Bush!
【生长习性】：The Marmalade Bush comes from the Andes mountain range, where the climate is mild all year. I have no information on how much heat it can take, but there are scattered reports of it growing in warm climates like Florida and Texas. I believe it is hardy only to about 28°F (-2°C). It is easily grown in a pot in well-draining soil. It likes mostly-sunny conditions, and regular watering & feeding. Over about 50% humidity is recommended.
【繁殖方法】：暂无。
【园林用途】：攀爬于廊架上或作地被均可。
