Q.When Can I Plant Primroses Outside?
My company frequently sells or gives away plants when they’re done using them. I have two primroses and live in PA. When is it safe to plant them outside?

If they are indoor grown primroses, I would wait until the chance of frost has passed. While they may be hardy, they will not have developed the hardening chemicals that outdoor plants produce to protect them from the cold and would be susceptible to frost.
