Passion fruit
Passiflora edulis
Also called Maracuja and Purple granadilla
Garden plant · Herbs, veg & fruitNOT the hardy blue passion flower on the garden wall — that one is a different species and its fruit is not worth eating. This needs a greenhouse or a conservatory in Britain, and it fruits on new growth, so prune it hard each spring.

Is it safe for pets and people?
No animal-poison authority lists this plant either way.
Nobody has checked this one against a source for us yet, so treat it as unknown rather than safe.
ASPCA holds no Passiflora in either section, and the RHS A–Z does not name it. That is an absence and not a clean bill.
Checked against ASPCA and RHS on 2026-09-22. Where a source says nothing, we say nothing.

First signs of trouble
- Spectacular flowers all summer and no fruit setting. Under glass there is nothing to pollinate it — move the pollen from the anthers to the three curved stigmas with a brush, in the middle of a warm day.Flowers, then nothing · disorder
- A fine sandy speckling over the top of the leaves and webbing in the leaf joints, on a plant in dry conservatory air. It is the commonest thing to go wrong with this one indoors.Red spider mite · pest
