85 Days. Another large meaty oxheart, Huge Lemon Oxheart tomato is certainly an all purpose variety. Reaching up to 1.5 pounds, this tomato stands out because of the consistency of its huge whitish fruits. Delicious, smooth and satisfying, this tomato makes any sandwich taste great! Like other oxhearts, vines are wispy leafed and skinny! Makes great sauce and salads when diced! Good disease resistance!
