Cherokee Purple: Indeterminate. 90 days to maturity. thought to have been passed down from Native Americans of the Cherokee tribe. Vigorous vines benefit from strong staking or caging.

San Marzano Tall Vine: Indeterminate. 90 days to maturity. AMAZING for sauce. Grows VERY well here in California.  We made the most delicious sauce last year.  San Marzano is the premier canning tomato with heavy walls, very few seeds and little juice

Mortgage Lifter: Indeterminate. 90 days to maturity.  Kentucky family heirloom grown since the 1930s.  Exceptionally meaty and typically crack-free.

Green Zebra: Indeterminate. 75 to 90 days to maturity. Flesh is bright green and very rich tasting, sweet with a sharp bite to it (just too good to describe!). A favorite tomato of many high class chefs, specialty markets, and home gardeners. Around 3 ounces each and Yield is excellent.


Companion planting is based around the idea that certain plants can benefit others when planted next to, or close to one another. 

Companion planting exists to benefit certain plants by giving them pest control, naturally without the need to use chemicals, and in some cases came mean a higher crop yield

Companion planting for tomatoes includes: Borage, Basil and Marigold (and more).  For a complete list, check out our companion planting guide.
