Plant Propagation
Pre-soak the seed for 12 hours in warm water, or scarify the seed, and sow in individual pots in a greenhouse in early spring. The seed usually germinates in 1 - 3 weeks at 22°c. Plants are extremely resentful of root disturbance, even when they are quite small, and should be potted up almost as soon as they germinate[219]. Grow them on fast in the greenhouse and plant them out into their permanent positions after the last expected frosts. Consider giving them some protection such as a cloche until they are growing away actively.
