|I live in New England, in zone 6, and would like a list of
hardy perennials for clay soil.
|Instead of thinking what will grow well in clay soil (not too many things!) you ought instead to consider amending your soil so ANYTHING will grow there! I lived in Connecticut for many years and had very heavy clay soil. I amended it by adding compost, compost and more compost! Every spring I dug whatever I used for mulch over the winter, into the soil. When the children were little and we had a sand box, we put new sand in every spring so we wouldn't expose the kids to any nasty "critters". Guess where we put the "used" sand? Yup! In the garden...dug it right in!
Gradually, your garden will become a wonderful, workable, plant-friendly medium. It would also help to get a soil test done. (Contact your Cooperative Extension office at 617-891-0650 for a soil test kit.) That way you can add any necessary nitrogen, phosphorus, potash or lime.
If you don't have a compost bin or pile...start one right away. Your garden will thank you for years to come!!
