There are three prolific plants alongside the deck, growing up a trellis. They have large, dark colored fruit, and are the only type of marble sized tomato that I now grow. They have a pleasant taste and are usually eaten raw. The fruit tends to ripen in clusters, facilitating picking. Splitting seems to be minimized, which is helpful. The fruit is produced until frost arrives.
