Flat-leaf
Giant of Italy Parsley is a robust Italian heirloom that delivers what its name promises: dramatically larger leaves and a more pronounced, vibrant flavor than the familiar curly varieties. This annual herb reaches maturity in just 35 days, making it one of the quickest herbs to bring from seed to kitchen. Frost-tolerant and rich in essential oils, it thrives in cool-season gardens and produces abundant harvests with minimal fussing.

The real draw here is the sheer flavor intensity. Giant of Italy packs significantly more essential oils than curly parsley, giving it a deeper, more herbaceous character that transforms dishes rather than merely garnishing them. The broad, flat Italian leaves are almost twice the size of standard parsley, so you harvest more substance with fewer plants. Surface sow the seeds and you'll be cutting fresh herb in little over a month.
Giant of Italy excels as a cooking herb rather than a delicate garnish. Chop it into minestrone, pasta sauces, and hearty vegetable dishes where its strong flavor won't fade into the background. It's exceptional chopped fresh into salsa verde, chimichurri, and herb butters where you want parsley to announce itself. The large leaves also work beautifully as a whole herb in slow-cooked broths and stocks, where they infuse depth without breaking apart.
Start seeds indoors 4 to 6 weeks before your last spring frost. Soak seeds for a few hours or refrigerate them for several weeks before sowing to improve germination rates, as this breaks dormancy. Keep soil between 50 and 70 degrees Fahrenheit during germination, which typically occurs in 14 to 35 days.
Harden off seedlings gradually over 7 to 10 days, exposing them to increasing sunlight and outdoor temperatures. Transplant to the garden once soil temperatures reach at least 50 degrees Fahrenheit. Space plants 8 inches apart in their final location.
Direct sow seeds outdoors in fall or in very early spring, working them into the soil surface. In cooler climates, fall seeding often produces stronger spring growth. For spring sowing in warmer areas, refrigerate seeds for several weeks before sowing to improve germination success.
Begin harvesting individual outer leaves once the plant is established, typically 35 days after germination. Pinch or cut stems at the base to encourage branching and continued productivity. The plant produces continuously through cool weather, so harvest regularly to maintain vigor and prevent flowering. Cut leaves are best used immediately but can be stored briefly in the refrigerator in a damp cloth.
Pinch off flower stems as they appear to redirect energy into leaf production and keep the plant productive longer. Harvest outer leaves regularly to encourage a fuller, bushier growth habit rather than allowing the plant to focus on vertical stem development.
