Planting
From Early Spring TO Early Spring
Grow in a dry, well-drained soil in full sun. The plant requires protection and does best against a south facing wall.
Propagation by cuttings
From Late Spring TO Early Summer
Take softwood cuttings from new growth early in the day in Spring or early Summer. Cut, neatly, a 4" approx. piece of a non-flowering shoot, pinch out the tip, and cut off the bottom leaves. Dip the bottom of the cutting in hormone rooting powder, and carefully place in a pot of cutting compost with the leaves just above the level of the compost. Water, label, cover with a polythene bag, and place in a warm, bright place, out of direct sunlight. Take the polythene bag off periodically for a while for ventilation (at least twice a week)
Flowering
From Late Autumn TO Mid Autumn
The blue flowers appear in late Summer until Autumn
