The wild foxglove can survive with very little water, but to grow tall and lush, they need plenty of water throughout the summer. For the best display, plant them close together in large groups. They will seed themselves freely if left to go to seed. Sow the seed evenly and not too thickly, in seed trays filled with a well-drained medium. Cover the seeds with a thin layer of white sand or fine milled bark, water well and place the tray in light shade.
Germination is usually very good, but the young seedlings are often a bit slow to grow initially.
They respond very well to feeding with organic fertiliser like Seagro or Humac as an initial boost. The seedlings can be planted into the garden as soon as they are big enough to handle, usually about 6-8 weeks after sowing. This is the only species of Ceratotheca that is found in South Africa. Ceratotheca means having horned capsules, from the Greek kerato -, horned and theke , a case. Cerathotheca triloba is used in traditional medicine to treat painful menstruation, stomach cramps, nausea, fever and diarrhoea.
