HEIRLOOM. 88 days. A succulent and enormous dark 1-1/2 to 2 lb. pink tomato that many gardeners prefer to the more acidic varieties. The flavor is sweet and very mild, and the large fruits are very attractive. Indeterminate. Pink-skinned tomatoes occur as a result of a clear skin over red flesh. (Ordinary red tomatoes have yellow skin over red flesh.) When ripe fruits retain green pigment, tomatoes take on purple and brownish hues.
