How to Plant Passion Flower Bulbs


Passionflower is a tropical climbing vine that produces both stunning exotic flowers and delicious fruits called maypops. Grown from underground rhizomes, passion flower is hardy in USDA zones 9 through 11 and thrives in protected locations with ample water, light mulching and something strong to climb and grow over.

Step 1

Select a planting location for your passion flower bulb that has nutrient-rich, well drained soil and a full sun to partial daily shade exposure. The more sun exposure, the more abundant the blooming and flowering.

Step 2

Dig a hole roughly twice the size of the rhizome or root ball. Dig the hole to be as deep as the rootball or 6 inches deep for a naked bulb. Loosen the soil in the hole to ease and speed root penetration. Place the rhizome in the hold and back fill soil to secure in place. Tamp down gently with your palms.

Step 3

Water in deeply and maintain evenly moist soil at all times below the surface. Water when the surface of the soil feels slightly dry to the touch. Depending on climate, time of year and size of the vine, twice weekly or more frequent watering may be required during the peak spring and summer growth seasons.

Step 4

Feed your passionflower with several inches of good quality compost twice a year applied as around the base of the vine as mulch. Passionflower vines are light feeders despite their vigorous growth habit and compost will feed the soil over time.
