I’ve five eccremocarpus scaber plugs that are growing well. I want to plant them in good sized containers to climb up a trellis. Will they be ok like this? I’ve grown cobaea in them in previous years successfully. Will I need more than one per pot? I could put one to run up a yew hedge, but don’t want to overwhelm the tropaeolum. Will they grow up a wall with a few wires?
