Germination guide
Aristolochia macrophylla seeds will usually germinate in 30-90 days, even under good conditions germination may be erratic. Sow Aristolochia macrophylla seeds on the surface of a Peaty seed sowing mix at about 25-30C.

Soak in warm water, which should be changed daily. Most seeds swell up when they are soaked, those that do should be sown immediately. Seeds that don't swell can be gently scarified.

(Soak 48 hours in hand hot water).
