If you sow parsley late in the year, you will have little use of it before it goes to flower the next spring.
Sow early in the year, indoors, with heat then you will have strong plants to enjoy cropping through the late summer, autumn and winter into spring when it goes to seed.
I think supermarket herbs are grown under optimum conditions which few of us can supply; maybe hydroponically. I find the tougher herbs like chives and thyme, etc. transplant most sucessfully.
Basil is a good herb to sow sucessionally and thickly in troughs in the greenhouse. Crop hard then discard. Ensure you remove the flowers and pinch out the tips frequently.
