Passion Flower Planting and Care Guide

Quick Facts About Passion Flower

Passion Flower vines are subtropical plants that provide an exotic look to the garden. The flowers are ornate and dramatic and the vines quickly climb fences, trellises, or out buildings. Passion Flower vines can even be grown indoors creating a lovely tropical atmosphere. The vines will produce egg-shaped fruit.

Planting Time

If the Passion Flower vine is going to be grown in a container (either as a house plant or simply brought in during the winter for protection), the seeds can be started any time. For vines that will be transplanted outside, start the seeds 8 - 10 weeks prior to the last expected frost.

Planting Location

Passion Flower vines like a full sun, hot, humid environment. They do best in well-draining, sandy loams. The vines quickly climb, so support and structure needs to be given.

How to Plant Passion Flowers

  • Prior to sowing, rub the Passion Flower seeds with fine grit sandpaper to help break the outer coat
  • Follow the sandpaper with an overnight soak in water
  • Fill small pots with moistened seed starter mix
  • Press 1 - 2 seeds into the soil and cover with 1/4 inch of soil
  • Loosely cover the pots with plastic wrap to help hold in moisture and heat
  • Warmth is important for germination, so heat mats are suggested to maintain 75 F
  • Lift plastic each day to make sure the soil is wet but not soggy
  • Once seedlings emerge, remove the plastic wrap
  • Seedlings grow quickly in bright light
  • Once the seedlings reach several inches in height and have true leaves, harden them off for 7 - 10 days prior to planting out

Care And Maintenance

  • Water the Passion Flower vine deeply when it is transplanted into its permanent growing location
  • Once transplanted, water the plant well 2 or 3 times each week
  • Provide a structure for the vine to climb
  • Apply fertilizer a couple of times during the growing season
  • Provide protection from wind
  • Depending on location, mulch the roots to give protection for the winter - plants can grow back in the spring from the roots
  • In colder climates, Passion Flower plants can be grown in pots and brought in to winter indoors
