This tropical vine features beautiful, exotic flowers. There are many different species and hybrids available with different colors and sizes of flowers. Without a greenhouse, or outdoor growing, the passion vine will be difficult to flower indoors. However, the plant is worth growing for its pretty foliage and vining nature. This plant is fast growing and can be trained to climb up anything. It is a great plant to use to frame your window, or to grow on a trellis. However, beware, this plant is vigorous, and will attach to and climb on anything that it is near (including other houseplants).
