Krishna Kamal (Passiflora incarnata), commonly called passion flower or maypop, is a vigorous perennial climbing vine grown across India for its mesmerising, almost mythological flowers. The blooms carry a ring of fine purple-and-white filaments (corona) over five petals and sepals, a structure that in Indian tradition is linked to the Mahabharata, giving the plant its devotional name.
The vine climbs rapidly using tendrils and can quickly cover a trellis, arch or fence, producing flowers chiefly through the warm, humid months. In favourable conditions it sets edible egg-shaped fruits known as maypops.
Easy to grow and tolerant of Indian heat, it dies back in cold winters in north India but resprouts from the roots, making it a reliable, long-lived ornamental climber for home gardens and balconies.

Care guide
| Sunlight |
Full sun to partial shade; at least 5-6 hours of direct sun for best flowering. |
| Watering |
Water regularly to keep soil evenly moist in summer; reduce in winter and avoid waterlogging. |
| Soil / mix |
Well-drained, fertile loamy soil, slightly acidic to neutral pH; enrich with organic compost. |
| Temperature |
Thrives at 18-32°C; tolerates brief cold but top growth may die back below 5°C, regrowing from roots. |
| Humidity |
Prefers moderate to high humidity; appreciates the monsoon season. |
| Fertilizer |
Feed a balanced NPK or compost monthly in the growing season; avoid excess nitrogen, which favours leaves over flowers. |
| Pruning |
Prune hard in late winter or early spring to control size, remove dead growth and encourage vigorous flowering shoots. |
| Repotting |
Repot container plants every 1-2 years into a larger pot with fresh, well-drained mix and a sturdy support. |
| Propagation |
Propagate by seed, semi-hardwood stem cuttings, or root suckers; cuttings root readily in the warm season. |
| Pests & problems |
Watch for aphids, mealybugs, spider mites and caterpillars; treat with neem oil or insecticidal soap. |
| Toxicity / safety |
Foliage of some Passiflora species contains cyanogenic compounds; keep unripe fruit and leaves away from pets and small children as a precaution. |
| Difficulty |
Easy |
Uses
- Popular ornamental climber for trellises, arches, fences, pergolas and balcony railings.
- Grown for its spiritually significant, eye-catching flowers in home and temple gardens.
- Attracts butterflies and other pollinators, supporting garden biodiversity.
- Ripe maypop fruits are edible, and the herb is traditionally used in calming herbal teas.
Growing tips
Plant at the onset of the monsoon (June-July) so the vine establishes in warm, humid weather, or in February-March after the cold passes in north India.
Provide a strong trellis or mesh early, as the vine grows fast and is heavy. Pinch young shoots to encourage branching and more flowering points.
In summer, mulch the base to conserve moisture and water deeply. In winter, in colder regions, cut back and mulch the roots; the plant will resprout in spring.
