Passiflora jorullensis

Natural origin of Passiflora jorullensis

Passiflora jorullensis is native to Mexico, Guatemala and El Salvador. Its habitats include moist mountain oak forests and forests with seasonal leaf fall.

Caring for Passiflora jorullensis

• Warmth: This vine prefers warm conditions. Keep it around 18°C or above where possible. Temperatures below about 15°C for long periods can stress new growth.
• Light: Choose a well-lit position. After it has gradually adjusted to brighter light, the vine can take direct sun in warm conditions, with light shade from intense midday sun behind glass.
• Water and drainage: Use freely draining compost in a pot with drainage holes. Water thoroughly when the surface has dried. Empty the saucer or outer pot after the excess water has drained.
• Support: Give the tendrils a trellis and guide loose stems with soft ties. Shorten the longest shoots if the vine becomes too large for its space.
• Humidity: Moderate room humidity is suitable. A humidifier can help in very dry heated rooms.
• Feeding: Feed on moist compost while stems are growing, following the fertiliser label. Feed less often when growth slows.
• Repotting: Move into the next pot size when roots form a tight circle around the rootball.
• Propagation: Young non-flowering stem cuttings can be rooted in peat-free cutting compost. Keep them warm, bright and lightly moist until rooted.

Problems and solutions for Passiflora jorullensis

• New shoots stop growing or become soft after a cold spell: Cold conditions are the likely cause. Give it a warmer, stable position sheltered from cold draughts.
• Leaves and young stems lose firmness while the compost is dry: Water shortage is likely. Water the rootball thoroughly and let the excess drain.
• Roots turn dark and soft, sometimes with a sour smell: These signs can indicate root rot. Cut affected roots back to firm healthy tissue with a clean tool, discard rotten material and repot in fresh, freely draining potting mix.
• Fine pale speckling and fine webbing appear on the leaves: Check the undersides for spider mites. Isolate the plant, rinse affected foliage and use a treatment labelled for spider mites on ornamental plants if needed, repeating it only as directed on the label.

Keep Passiflora jorullensis away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.
