Have planted seeds sent to me from cancer charity in memory of my brother. Put them in a pot due to lack of garden space have grown amazingly . Do I need to cut them back at the end of summer or will they just reflower next year,they are still flowering now..
Forget Me Nots
Myosotis, the forget-me-not genus, contains many different species. Most are short-lived but since they reliably self-sow, it's as if they were perennial. Cutting back isn't necessary and will not prolong bloom time. Because it sometimes acts as a biennial and dies after flowering, let the seeds mature and collect some and let the rest fall will they will. There will be new plants in your container and your garden next year.
