It doesn&#8217;t go crazy with suckers, very well-behaved. The fruits are dark maroon, heart-shaped, large (mine were up to 21 oz \/ 600 g), and just freaking delicious. The yield is average, but for the sake of this flavor, it is absolutely worth growing. It fruits evenly across all trusses; after the first and second trusses ripen, it sets fruit perfectly on the upper ones too. There are 2-4 fruits per truss, and the upper ones are not small at all. I will definitely be planting it again.<\/p>\n<p><a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3764_fc1d6cf7ca03f49ad5ae924adb7c65c5f0f1022d.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3764_fc1d6cf7ca03f49ad5ae924adb7c65c5f0f1022d.jpg\" alt=\"Large dark maroon Black Oxheart tomato sitting on a scale\" width=\"819\" height=\"614\" \/><\/a><br \/>\n<a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3766_ab091c3ca484b644662bdc7c87277b1c497bf633.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3766_ab091c3ca484b644662bdc7c87277b1c497bf633.jpg\" alt=\"Perfect heart shape of the Black Oxheart\" width=\"819\" height=\"614\" \/><\/a><br \/>\n<a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3768_0593792464f40000ae2505018510a111383ff16f.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3768_0593792464f40000ae2505018510a111383ff16f.jpg\" alt=\"Cluster of dark tomatoes on the vine\" width=\"819\" height=\"614\" \/><\/a><br \/>\n<a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3770_304288820c4b9e0d94636679622a01a19e06b728.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/3770_304288820c4b9e0d94636679622a01a19e06b728.jpg\" alt=\"Sliced Black Oxheart showing meaty dense interior\" width=\"819\" height=\"614\" \/><\/a><\/p>\n<\/div>\n<\/div>\n<div class=\"forum-post\">\n<div class=\"author-header\">\n<div class=\"forum-avatar\">M<\/div>\n<div class=\"author-meta\">\n<div class=\"author-name\">Marina <span class=\"author-stats\">\u2b50 Pro Grower (5,182 posts)<\/span><\/div>\n<\/div>\n<\/div>\n<div class=\"post-content\">\n<p>I had two plants and both were sickly, the leaves turned black.
