The passiflora is a fruit producing, herbaceous vine that can grow up to 25 feet long. This perennial is a showy vine that carries purple petals and deciduous, three-lobed leaves. Passiflora plants are the flowers of the passion flower family and include the purple passion flower, the purple passion vine, the maypop and the apricot vine.
Plant your passifloras in fertile, well-drained soil. Prepare the planting area by digging a hole approximately two to three inches deep. Line the bottom of the hole with a layer of compost. The plassifloras will benefit from the aeration and drainage provided by the compost. Scatter the plassiflora seeds throughout the hole and fill the hole with nutrient soil.
Ensure that you select a well-lit area of the garden or planting location. Passifloras require at least eight hours of direct sunlight each day to thrive and grow. These flowers will thrive in partial shade areas that provide a minimum of six hours of direct sun each day.
Fertilize your passion flowers monthly throughout the growing period. Passifloras are vigorous growing plants that experience blooming periods from April through September. Use a fertilizer that is high in potassium, contains micronutrients and low levels of nitrogen. This combination will promote a strong plant structure and flowers with longer bloom times. Use a high-nitrogen fertilizer during the winter months to promote its hardiness.
Water your passifloras regularly, being careful not to over-water. Passion flowers benefit from moist to dry soil. Passifloras normally will require bi-weekly watering in the spring and daily watering in the dry, summer months. Regular watering will promote continuous blooming throughout the warm months. Passifloras generally benefit from the same watering schedule as its surrounding grass.
Control the growth of the passiflora by pruning it regularly. Passifloras are vigorous growers that can become invasive and overpowering. Remove the suckers of the passiflora regularly to control its expansion and redistribution. As the vines continue to grow, propagate the vine by splitting the roots and transplanting them to their new location.
Harvest the passion flower's fruit toward the end of the summer months. The fruit will develop as a yellowish-green fruit that is roughly the size of a small egg. Ripened fruit will have a sweet, yellow pulp. Pick the fruit when it is soft and a light, yellowish green. Remove the dropped fruit from around the base of the vine, as this will promote decay and disease if not removed.
