Used as a garnish or directly in dishes, parsley is a delicate herb with a strong peppery taste, making it a favorite for many chefs. As a biennial, edible white flowers emerge in an umbel during the plant’s second growing season. An attractor of butterflies and other beneficial insects, this herb will not only benefit your palate, it will also spruce up your garden. Seeds possess an extremely thick coat which can cause the germination process to take some time, so be patient!

As the name would suggest, Italian Dark Green Flat Parsley is known for its dark green flat leaves as well as its capability to grow quite quickly. Whether growing indoors or in your garden, this parsley is relatively easy to maintain, as it is more tolerant of temperature changes than its curlier cousin.

Grows best in moderate climates. Prefers cooler weather to heat and will likely become stunted or die if exposed to temperatures over 80°F for prolonged periods of time.


Natural: Full sun. Provide light shade when growing in hot weather.

Artificial: A great candidate for indoor growing, parsley can be started under fluorescent lights or even on a sunny window sill.

Growing Media

Soil: Prefers a rich, loamy soil. A pH of 5.2 to 6.0 will keep plants healthy and nourished.

Soilless: A great candidate for indoor growing, parsley will grow well in most soilless mixes such as perlite, coco coir, rock wool, or vermiculite.

Hydroponics: Can be grown in a hydroponic system. Placing the seeds in warm water and changing it out often will help the seeds germinate more quickly. Use a medium such as rock wool to grow your seeds once they are ready.

Aeroponics: Will thrive in an aeroponic system.


Water: Requires low to moderate levels of water. Soil should be kept moist but not saturated except in the earliest growth stages when seeds are germinating.

Nutrients: A heavy feeder, parsley needs nutrient-rich soil, so fertilizer may be needed if your soil is not the best quality. A balanced nitrogen, phosphorous, and potassium fertilizer will generally do the trick and should be applied prior to planting and after your first cutting if harvesting more than once in a season.

Pruning: Cut plant back with scissors or by hand throughout the growing season to encourage new shoots and broader leaves.

Mulching: Use mulch to retain soil moisture and suppress weed growth.
