Yes. I plant in the ground and it usually overwinters well. I had to replant after that minus 15 degree plunge the winter before last. The lavender I planted with the grapevines did very well and one plant is getting ready to bloom already. Potted or container plantings will likely not survive the winter.@Wee Farmer Sarah should I plant my lavender in the ground or in a raised bed (that has no bottom). Maybe in the ground & cover with leaves for the winter (this is what I did last time)? Is yours directly in the ground?
