What sort is it? Is it a fruiting sort? It should flower on older wood, the flowers are quite insignificant. Don't prune out older wood.

Mine flowered for the first time this year and I've had it 5 years. It is supposed to be self fertile but the little kiwis blew off :(. Flowers are actually quite pretty. I like the vine for its leaves and habit anyway so I'm not too concerned. You do have to wait a while for it to flower though.

Hi, Ssmith--I take it you mean the plant, not the bird!!
Ho! HO! Annie
