Q.How much drainage does lambs ear need?
I planted lambs ear as a border last year in a new garden and it grew great. I loved the look. We are a zone 3-4 and had a cold winter with not much snow cover. We had a very wet spring, 8″ rain in April, not one of the lambs ear survived. We also have clay soil and so not very good drainage, but the plants get sun/some shade. Is there a variety that would survive the poor drainage? Do you think it was the wet spring or cold winter that kept them from surviving? Any other perennial that you would suggest for a lower height border?
My Lambs Ear did not survive this past winter in my Zone 4 garden also.
If you replant, you will need to make sure it is planting in well draining soil.
Amend the clay soil with compost.
