Cress is a fast-growing, edible herb that is also known as garden cress, pepper cress, or curly cress.  It is an annual plant that can grow up to 24 inches tall. The leafy green plant is a member of the Brassica family of vegetables.  The plant is related to watercress or mustard and shares its peppery, tangy flavor and aroma.  It is often grown as a microgreen and used in salads, sandwiches, and soups.  The plant does produce small white flowers, but once the flowers appear the plant is not really edible as the taste becomes bitter.  Cress is easy to grow.  The plant does best in extremely moist soil, so don’t forget to water the plant.  Cress likes full sun unless you are growing it in a warm climate, in that case, plants it in partial sun to protect it from the heat.  Cress is hardy for zones 6-9.
