Lycopersicon esulentum "Oxheart" tomatoes are very large and irregularly heart-shaped, often considered an heirloom Tomato.
Like all tomatoes they are annuals, or short-lived perennials
They have soft, pungent, hairy stems and branches profusely (pinch out tips to promote good fruiting).
Small yellow flowers turn to green globular succulent fruit that mature, in sunny conditions, to red, yellow or sometimes even stripy fruit.
They are frost tender so in frost prone areas they are best grown under cover until risk of frost has passed.
