Now is the time (before late September) to direct sow seeds of cool season annuals such as cornflowers/bachelor buttons, larkspur, breadseed poppy, corncockle, love-in-a-mist (Nigella), and Chinese forget-me-nots. These will sprout in place in your beds when the time is right, during late winter and early spring. Don't clean up the bed too much - leave the seeds in place.
