The Cherokee Purple tomato is said have originated more than 100 years ago with the Cherokee people. This beefsteak-type fruit is deep purple with green shoulders, is densely textured and has a mild, sweet tomato flavor. Because it is an open-pollinated heirloom variety, seeds are easily saved from year to year and return true to type.
The fruits of Kellogg’s Breakfast are a brilliant orange and have a tangy flavor. They are thin-skinned and meaty with very few seeds. This tomato variety is the favorite of many gardeners. An open-pollinated heirloom, it hails originally from West Virginia, but was acquired by a Michigan breeder named Darrell Kellogg. Plants must be properly trellised or staked as the fruits are very heavy and the vines alone cannot support them.
The Sweet 100 cherry tomato is a hybrid variety that bears hundreds of super-sweet bright-red fruits all season long. Because the plant can grow quite large, a good staking system or tomato cage is necessary.
