Nice picture Bill.
I have in a few areas.The leggy area is mostly sandy and can't say its spreads invasively there,but the compost-enriched bed does well.When you move it keep it watered for 2 weeks roughly daily& if are real rooty can trim roots a lil,it will make newer ones.I already can see my one bed is going to go to a cottage look now.I added compost to bed and lifted
plants out...lined them up in a row then re planted them.I may have a monarda clump at one end,but are
seedlings of different hights in the whole bed.Its probably going to look like my pink primeroses did...one small start and I guess it had seeded and covered the whole front half of bed where added compost to raise bed higher.I'll be spreading those out soon too so can
seed in other areas.
I have mostly pinks,hopefully some of the
seeds i've traded for will be REd.
