Q.can I plant lambs ear in April?
I live in New Jersey and I received my lamb’s ear plant. I am concerned that we will still have frost — is it OK to plant it in the ground now?
Lamb's ears are hardy to zone 4. It can be planted out this spring when the ground has thawed, and I would suggest waiting until danger of frost has passed.
My recommendation would be to keep it in a sunny location indoors and care for it until it's safe to transfer outside. It really won't be long to wait to insure it's success in your garden.
Here is a link about lamb's ears.
