How to Grow a Purple Passion Plant

Grow a purple passion plant outside as an annual or inside as a houseplant. The plant can thrive in both situations. You can also grow the plant in a pot, place it outside from spring through fall and bring it inside during the winter.

Plant a purple passion plant in a pot, even if grown outdoors. The plant will spread outdoors and may get out of control. If you are looking for a thick ground cover, however, the plant will grow in the ground.

Provide a purple passion plant with bright light. The bright light is necessary to encourage the purple highlights in the leaves and flowers to form. However, too much direct sunlight can burn the plant, so if grown inside, grow in a west or east window or a south window with a transparent curtain. Outside, give the plant partial shade near a tree or on a porch.

Keep the soil moist. Water the plant when the top of the potting mix begins to dry out. If grown outside, the plant may need water every day to keep the soil moist. Inside, the plant should be watered at least once a week.

Trim the ends of the stems regularly. This will cause the stems to branch, keeping the plant full, and increase the brilliance of the purple color.
