Gardeners! Landscapers! I have a big pile of lavender scallops I pulled up in my yard. Easy to grow. Many of the branches still have roots and many of the lower stems have also put out runner roots to anchor in the ground and spread. Take as much as you can. Pile includes cuttings and branches that can be transplanted as well as dead wood and some weeds I dug up, but it'll be pretty easy to just pick out the good branches.
