Rosemary brings resinous, piney perfume to roasted meats, potatoes, and focaccia—and it’s a handsome evergreen shrub in mild climates. Traditionally used as a memory tonic and antiseptic rinse, it’s still valued for its concentrated essential oils. Start seeds early and patiently; rosemary is slow to germinate and grow. Once established, give it full sun, sharp drainage, and a light hand with water. Prune lightly after bloom to keep plants compact and take cuttings for easier future starts. In colder zones, pot it and winter indoors by a bright window. A little goes a long way in the kitchen—and in the garden, too.

How to Grow

Start seed indoors 8-10 weeks before transplanting into the garden. Cover soil very lightly as seeds require light to germinate. Optimum soil temperature for seed germination is 70-80 degrees. A heat mat will improve germination.
Sow thickly as germination is naturally low and variable.
Transplant to the garden 1-2 weeks after your average last frost date.
Perennial in zones 6-10

Excited

Rosemary, no matter where you purchase, has a low germination rate. I sprinkled at least 30ish seeds onto my potting soil, and topped it with a sprinkle of vermiculite. I managed to get 10 to sprout! Unfortunately, I killed some transplanting lol. But excited to see these babies grow.

We're sorry to hear about your experience with our rosemary seeds, Donna. We strive to provide high-quality seeds, and it's disappointing to learn that the seeds didn't germinate as expected for you. We recommend starting rosemary seed indoors & cover soil very lightly as seeds require light to germinate. A heat mat will improve germination. Sow thickly as germination is naturally low and variable. Seed germination can take between 14-21 days. Customer support will be reaching out through email to help resolve this for you.
