Moderate
Passiflora alnifolia, commonly known as the Alder-leaved Passion Flower, is a rare and exotic climbing vine native to the Andean cloud forests of Colombia and Ecuador. This species produces stunning white, lavender, and purple sweetly-scented flowers with delicate filaments and simple, unlobed leaves resembling alder tree foliage. Seeds have a hard dormant coat and germinate best with warm temperatures, light scarification, and soaking pretreatment, typically emerging within 4-8 weeks under optimal conditions.

Growing Tips
Provide bright, indirect light during germination and growth. Maintain consistently moist but well-draining substrate; avoid waterlogging. Keep seeds and seedlings at 25°C for fastest germination; germination slows significantly below 15°C. Sow preferably in spring but can be attempted year-round. Protect young plants from cold; not frost-tolerant below 10°C. Once established, prune to encourage bushier growth and more abundant flowering. Provide climbing support (trellis, mesh, or strings) as plant grows. Use balanced fertilizer every 2-3 weeks during active growth. This montane species appreciates cool nights and good air circulation.
