Growing directions
Curly parsley is a hardy biennial grown as an annual for its bright green, frilled leaves used as garnish and seasoning. Germination is slow, so soak seed overnight and keep the soil consistently moist. Harvest outer stems first and the plant will keep producing from the center. In milder zones it overwinters and flowers the second year, at which point flavor declines.
