Growth and harvesting
Chard is a biennial. Clusters of chard seeds are usually sown, in the Northern Hemisphere, between June and October, the exact time depending on the desired harvesting period. Chard can be harvested while the leaves are young and tender, or after maturity when they are larger and have slightly tougher stems. Harvesting is a continual process, as most species of chard produce three or more crops.[13]

Cultivars
Cultivars of chard include green forms, such as 'Lucullus' and 'Fordhook Giant,' as well as red-ribbed forms, such as 'Ruby Chard' and 'Rhubarb Chard.' [2] The red-ribbed forms are attractive in the garden, but as a general rule, the older green forms tend to outproduce the colorful hybrids. 'Rainbow Chard' is a mix of colored varieties often mistaken for a variety unto itself.[2]
Chard has shiny, green, ribbed leaves, with petioles that range in color from white to yellow to red, depending on the cultivar.[2]
Chard may be harvested in the garden all summer by cutting individual leaves as needed. In the Northern Hemisphere, chard is typically ready to harvest as early as April and lasts until there is a hard frost, typically below 25 °F (-4 °C).[citation needed] It is one of the hardier leafy greens, with a harvest season that typically lasts longer than that of kale, spinach, or baby greens.
Culinary use

It is one of the most common ingredients of Croatian cuisine in Dalmatia region, being known as "queen of the Dalmatian garden" and used in various ways (boiled, in stews, in Soparnik etc.). [17]
