South Africa has by far the world’s richest flora. A mind-blowing range of trees, shrubs, herbs and bulbs flourish in bushland, fertile plains, forest, semi-desert and the sea shore. Even in the darkest forest, there are treasures that thrive and flower in the shade. Notable among those are clivias or Natal lilies. These are sturdy perennials with shocks of dark strappy leaves and in late winter or spring, big orange flowers. I’ve seen clivias in deepest shade and even sprouting from rock crevices. Alas, they’re not quite hardy enough to live outside here in the UK. But they make fabulous house or conservatory plants and will flourish, even in low light. The large, showy umbels of gorgeous tangerine blooms pack a massive floral punch between February and May. The handsome, hollygreen leaves stay fresh and green all year.

BUYER BEWARE The common wild Clivia miniata is the easiest to grow. It has large funnel-shaped flowers, carried on durable stems. If the plants are well-grown, flowers are held well above the foliage. The soft amber-orange petals contrast beautifully with the leaves. Each has a paler throat and though most are scentless, some forms have a gentle fragrance. Young clivias are widely available. Garden centres frequently offer them, as do mail-order suppliers. There are also named varieties in different colours – mostly yellow or cream. But be cautious if shopping online. When I typed ‘Clivia miniata plants’ into the Amazon web-site, up came a mix of luridly coloured freaks. Some were cobalt blue and one picture showed a stem with flowers in a lurid rainbow mix. Such things are genetically impossible. So buy from reliable sources. Seed and plant […]
