Other Comments:
Several planted along fence mostly full sun daily, watered daily, very vigorous with new tendrils everywhere daily. Pruned in attempt to “kick start” flowering. Local nursery at a loss to understand why no flowers.

Do flowers come from the new growth tendrils or elsewhere ? Sorry I am a new gardener having spent my working life at sea.

Hi Bill, Kennedyas are mostly ground-growing plants suited to semi-shaded areas. They usually flower in their first year from seed. All that I can guess is that you are over-fertilising them. They prefer rather tough conditions and over-fertilising might just send them into a major growth spurt. Try some neglect. Don
