I was just wondering...what makes a nep produce basal shoots? I would assume age doesn't necessarily have anything to do with it since I have young neps (mirabilis and truncata) producing shoots and an older one (ventricosa) that never has. Are some varieties more prone to do that than others? Can you do anything to force a plant produce a shoot (other than cutting the vine)? I'm just curious since some of mine are producing shoots and some aren't.
