About

Italian Giant Parsley is a flat-leafed biennial herb native to the Mediterranean that reaches 12–14 inches tall with large, dark green, flat leaves. Giant Italian Parsley has a cleaner, bolder flavor than the curly type. Hardy in USDA Zones 3–9, it's technically a biennial but most gardeners grow it as an annual. In the kitchen it can be added fresh in salads, stirred into soups, blended into sauces or pesto or used as a garnish. It is also very beneficial in the garden, because it attracts hoverflies and parasitic wasps — the insects that deal with aphids.

How to Grow & Harvest

Sowing & Timing

Parsley is a slow germinator — 14-28 days from sowing to first sprouts. Soak seeds in warm water for 12–24 hours before planting to speed up germination time. Start Italian Giant Parsley seeds indoors 2–3 weeks before the last frost. Press seeds ¼ inch deep into a moist seed-starting mix. For direct sowing, wait until soil is above 50°F. Always put a few extra seeds into the hole, as Parsley germination rates are lower than most herbs, and empty patches would be hard to fix.

Soil, Watering & Fertilization

Italian Giant Parsley needs at least 6 hours of direct sun to grow well, though afternoon shade is tolerated in zones 7–9. Parsley herb grows in loose and fertile soil. Compost-amended loam gives you noticeably bigger, more productive plants. Water regularly and don’t let the soil dry, as it speeds up bolting. In containers, check soil moisture daily in warm weather since pots dry out much faster than garden beds.

Growth & Harvest

Giant Italian Parsley is a low-maintenance once established. Feed with a balanced liquid fertilizer every 4–6 weeks to keep leaf production steady. When harvesting, always take outer stems first and leave the central growth intact. Mulch around the base to hold moisture and reduce weeding.
