I have one of those hydroponic counter top devices and these seeds germinated well and the lettuce is delicious.
The name Cress describes a number of fast growing, powerfully flavoured greens that are harvested as immature leaves to add pizzazz to salads and sandwiches. They are botanically distinct from true watercress, but share a flavour profile that is peppery and delightful. Look for true watercress under the Salad Greens category.
