75+ Seeds. Giant Belgium is an heirloom variety from Ohio dating back to the 1930's, although its name and shape suggests roots in the old Belgian ribbed tomatoes. Plants produce large quantities of huge fruit; with some as large as five pounds (my personal best is 3.3 pounds). Giant Belgium tomatoes are very sweet, meaty, and turn dark pink when mature. A low-acidity tomato that is excellent for salads, sandwiches, and canning. The pink skin occurs as the result of clear skin over red flesh, while most red tomatoes have a yellow skin over red flesh. Indeterminate, Open-Pollinated, 85 days from transplant. Origin: Ohio, USA.
