Forget me nots are considered either a short lived perennial or a biennial flower that self sows very easily. Direct seed in early spring a few weeks before the last frost. Or, sow seed in late summer/early fall for flowers the following spring. 'Victoria Blue' is a nice, compact form. Never deadhead forget me nots. Let the seeds drop and learn to recognize the babies, perhaps moving them to new spots. There is nothing like a carpet of blue forget me nots in bloom!
