I planted Eucomis "Tugela Jade" two years ago in a bed which I don't water unless absolutely necessary. The soil is clay, leavened with compost and mulch, but reasonably free-draining because it's behind a retaining wall. Sun most of the day. The Eucomis have produced lots of healthy leaves each spring, but to date no flowers. Is it a question of patience on my part, or do I need to water more (given that, as I understand it, these come from a summer-rainfall part of South Africa). All suggestions welcome! Caroline
