Is there any way else to propagation lavender besides from seeds?

Lavendular - Propagation other than by seeds: Plant cuttings in a cold frame in summer or outdoors in autumn.

The cutting should be soft and green at the top, but somewhat stiff at the base. The cutting must be planted quickly and not left to dry out.

Further information: Take 3-4in cuttings of ripe non-flowing shoots and insert in equal parts (by volume) peat and sand in a cold frame.Overwinter the cuttings and transplant to their flowing positions in March-April
