Passiflora macrophylla

Passiflora macrophylla or big leafed Passiflora is a remarkable Passiflora with huge leaves of 1 m long.

It is the Passiflora with the largest leaves.

It is also one of only 3 Passiflora species that grows as a tree and not a climber, with Passiflora arborea and Passiflora lindeniana.

The leaves fall between growth spurts making the plant look dead.

It needs a lot of heat and is really only suitable for the garden in the tropics. Elsewhere, it must be grown in a heated greenhouse.
