Rosemary is an excellent herb to grow for novice gardeners. Cooler zones below zone 6 will need to treat rosemary as an annual as it is not wintering tolerant. Used widely as an herb or for medicinal purposes. Not well known, but Rosemary will attract bees.
Rosemary may overwinter in colder climates if mulched or dug up and transferred to containers in a protected structure. If using primed seed, press seeds into the top of the growing medium. Germinate at 70°F (21°C). Treat the same as unprimed seed after germination is complete
