Oregano, also called origanum or wild marjoram, aromatic perennial herb of the mint family (Lamiaceae) known for its flavourful dried leaves and flowering tops. ... Culinary varieties, such as Greek or Italian oregano, have a strong aroma and a warm pungent taste.
Oregano needs to have the soil dry out a bit in between watering and benefits from frequent haircuts to keep the plant compact and producing leaves.
Cut back the stems of the oregano plant using pruning shears to a height of 2 or 3 inches about six weeks after planting. If the oregano plant is regrowing from the previous year, wait six to eight weeks after the plant's new growth begins in spring to prune it back.
Indoor oregano plants need similar conditions to exterior raised plants. The ideal temperatures for growing oregano inside are between 65 -70 F. (18-21 C.) in the day and 55-60 F.
