Other uses of Perennial Sweet Pea:

Plants can be grown without supports when they will sprawl on the ground and can be used as a ground cover plant in a sunny position. They should be spaced about 1.5 metres apart each way. They are very vigorous and so are best not used with small plants. They also die down completely in the winter, giving weeds a chance to become established.

Propagation of the herb:

Pre-soak the seed for 24 hours in warm water and then sow in early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed, then it can also be sown in situ in mid spring. Division in spring. It may not transplant well so care should be taken.
