Passiflora caerulea | Lived | -18 | 8 | 1yr | 6B | Unheated greenhouse | Saros | Died back to roots.. It was in a pot sitting in the corner of a raised bed in my greenhouse. Last year it grew roots through the bottom of the pot and firmly planted itself in the bed. The potted portion of the plant died during the winter. I thought the whole plant died until I noticed passiflora growing out of the complete opposite side of the bed. Apparently it lived on under the soil in the bed and came back from the roots. |
