Hewitt's Garden Centers > Questions > Hi, wondering how long perennial seeds last. I have a variety of packets from last year and wondering if they will germinate or if they are too old. FYI……my annual zinnia seeds have worked year after year, as I have a big box of them!Is that even normal for zinnia seeds? Thank You
