This spring I got my first passionflora, Passiflora caerulea 'Clear Sky'from Grassy Knowl. It did fantastic in a pot with a trellis growing to about 12 - 15 feet by July 4. It flowered regularly (no fruit however) and continued to send out new tendrils. Now, it seems there is not new growth and not many more young buds. I water and feed regularly. The foliage is healthy and green. It looks like a very healthy plant it just doesn't seem to be growing anymore. It is in a 18 inch pot in a full sun location. Is this normal?
