Overwintering passiflora coccinea — FAQ
Does passiflora coccinea need to come indoors for winter?
Passiflora coccinea is hardy to roughly USDA zone 10 — winter lows around -1°C. That means it will not survive frost and needs to come inside. Passiflora coccinea is frost-tender, so overwintering means bringing it inside and letting it rest rather than pushing it to grow. Move it indoors well before the first frost, give it the brightest spot you have (light levels indoors drop sharply in winter), and keep it away from both cold window glass and hot radiators — the swing between the two does more damage than the cold itself.
When should I move passiflora coccinea for winter?
Bring indoors when nights start dropping below about 10°C, ahead of the first frost.
