Parsley (Petroselinum sativum): this beloved plant, a staple in Italian kitchens, needs no introduction.
 Easy to grow, suitable for pots, so you can always keep it close at hand and fresh. It can be sown from spring to fall, placing the pot in a cool place for a prolonged harvest.
 Harvest it by cutting it at the base; it will quickly produce new leaves. It's helpful to cut it periodically to encourage the plant's regeneration. The soil should be kept moist, but don't overwater.
