Parsley is a hardy biennial herb grown as an annual in UK gardens. Seeds take 3-4 weeks to germinate at 15-20°C. Soaking seeds overnight in warm water speeds germination by up to a week. Flat-leaf varieties offer stronger flavour than curly types. Plants tolerate partial shade and grow well in containers at least 20cm deep. Sow outdoors from April to June for harvests from June to December.
