Kardynal tomato is a very pleasing oxheart variety. Healthy plants produce a lot of 6-8 ounce oxhearts that are really versatile. They are so good for slicing too! I had two very good sandwiches with these and they were memorable. With very good texture and balance, these are neither sweet nor tart. What comes through for me, is its overall completeness that remains true to most oxhearts. Plants are not too tall. Great disease resistance! Another one that I will grow again!
