About Parsley

Parsley is a biennial grown as an annual — slow to germinate but then productive for months.

Soak seeds overnight before sowing to speed germination. Can take 3-4 weeks to sprout — be patient. Harvest outer stems. Will survive light frost. Good for containers and windowsill growing.
