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. |

Growing tips
<p>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.</p><p>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.</p><p>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.</p>
