Overview

Passion flowers (Passiflora incarnata) require partial-shade to full-sun in well-drained soil. Hanging baskets provide ideal growing conditions for the perennial indoors. The vine droops over basket containers to reach an average height of 6 feet and spread of 3 feet. Moving the basket outdoors for several hours of daily sunlight provides the opportunity to attract butterflies. Novices and experienced gardeners have success growing passion flowers indoors.

Step 1

Mix 1 part peat and 1 part potting soil in a small bucket. Fill potting containers three-quarters with mixture. Place a small hole in the center of mixture. Place two seeds per container. Water until soil is moist.

Step 2

Mist seeds daily with water to germinate. Once sprouts appear, remove the weaker sprout from the container.

Step 3

Place indoor passion flower containers in a partial to full-sun window location for optimum light requirements.

Step 4

Combine 1/2 part peat into current indoor passion flower containers or when setting up new transplants to improve soil drainage.

Step 5

Place a small, oscillating fan several feet away from indoor passion flower containers to improve air circulation and decrease chances of fungus growth.

Step 6

Water the indoor passion flower containers when the upper 2 inches layer of the soil feels dry to the touch.

Step 7

Spray a pair of pruning shears with disinfectant to sterilize. Prune away any brown, damaged or diseased sections of the vine throughout the spring and summer.

Step 8

Thin the lower quarter branches of indoor passion flower containers starting at the base of the plant at the beginning of fall. Remove a quarter of the branches with sterilized pruning shears.

Step 9

Cut blooms 2 inches past the base of the flower blossom for fresh flowers or when blooms fade, throughout the growing season. Use sterilized pruning shears.

Tips and Warnings

  • Never place passion flowers in direct drafts or near the oscillating fans. Too much moisture and water increases chances of diseases. Avoid over-watering indoor passion flower containers.
