How to Overwinter Pimpernell - Anagallis Skylover Blue

Hi. I'm writing from Calgary Alberta, Canada and Zone 3. I purchased 3 Pimpernell - Anagallis Skylover Blue and they've all done great in my garden. Now it's September, and I'd like to overwinter these plants. Can I pot them up and store them in a dark cool place? I'd like to try to keep these as opposed to seeding from scratch in the spring.
Many thanks, Susan

    In UK it is a tender perennial

    I think your winters are very cold.Maybe you need to bring it inside.

    • Garden care: Keep the soil or compost moist by watering regularly during dry spells and feed with a balanced fertiliser every fourteen days. Take care not to overwater in the early stages. Although usually grown as an annual in this country, plants that are protected with a dry mulch may survive mild winters where temperatures only occasionally fall below 6 to 8°C (42 to 46°F)
