Tomato Yellow Grapes (Tobia's Select Seed, USA)
Yellow Grape tomato varieties share several common characteristics: they are petit, glossy and thin-skinned, with two seed cavities, and they are known for their low acidity and mild, sweet flavors. The plants of the tomatoes are characterized as either determinate or indeterminate: determinate, or bush, varieties do not need pruning and may be grown with or without support. The fruit of determinate plants ripens within a concentrated time period. Indeterminate, or climbing, varieties should be staked, trellised, or caged, and pruned for best results. The fruit of indeterminate plants ripens over an extended period of time, as their name implies.
