The purple passion vine (Gynura sarmentosa) is a perennial vine, generally grown as a houseplant. The plant derives its color from the purple hairs along the stems and on the foliage. Native to Indonesia, purple passion vine can be trained to a small trellis or allowed to spill over the side of the container. Overall, it is easy to care for and provides a jolt of color to the interior of the home.
Plant your purple passion vine in two parts peat moss, one part potting soil and one part sand.
Place the purple passion vine in an area that receives bright light, but not direct sun. The more light the plant receives, the more purple it becomes.
Water the purple passion vine when the soil is dry. If it begins to wilt, it is time to water it.
Fertilize the purple passion vine once a week with a balanced houseplant fertilizer. Dilute the fertilizer to half the strength suggested on the label. Discontinue fertilizing in the winter.
Remove any flowers that the plant may produce in the spring. They have an unpleasant odor and blooming causes the plant to decline.
Pinch the tips of the vines to create a bushier plant. The cuttings removed can be place in the soil and will grow roots.
Cut the purple passion vine back in the winter such that only four nodes (the place on the vine where the leaves join it) remain.
