The passion fruit vine is more than just a fruit producer—it's a permaculture powerhouse. Discover how this prolific climber is used to shade a south-facing wall in summer, yet dies back in winter to allow passive solar heating (stacking functions at its best!). We share our experience with the high-yielding 'Frederick' variety and why you must build a dedicated, robust support system (no flimsy fences allowed!). Plus, see how we transform our daily harvest of 3–5 fruits into a versatile, must-have syrup.
