Sweetie Cherry Tomato Seeds. The sweetest cherry tomato you will ever taste! Small 2.5 cm (1″) (approximate size) fruits form in clusters on long branches. This variety should be staked for maximum production. Use for preserves (believe us, they wont need any extra sugar) or eat fresh from the garden. When this variety starts to produce, you had better get the wheelbarrow out — you will need it to haul in the crop! Semi-determinate growth pattern.
