History and seedkeeping context
Green Zebra is a modern open-pollinated cultivar developed by tomato breeder Tom Wagner and introduced in the 1980s. It was selected for fruit that remains green when ripe while developing yellow striping and a noticeable change in softness and flavor. Because its documented introduction is modern, this page does not call Green Zebra an heirloom even though it is now widely grown and seed can be saved from properly isolated plants.
Its modern breeding history and distinctive ripe-green color are preserved as part of the cultivar's identity. Green Zebra is maintained in this catalog as an open-pollinated (op) slicing tomato. Published records support the cultivar name and the observable fruit and plant traits used on this page.
Where the available documentation does not preserve a complete breeder, family, or community chain, Species-level tomato domestication in Andean South America is kept separate from the later history of this named cultivar, which may involve farmers, public breeders, gardeners, market growers, and seedkeepers in other regions. The listed heritage classification is Non-GMO; it describes the catalog classification and does not prove an undocumented origin story.
Fruit, flavor, and kitchen use
Green Zebra is best for fresh slicing, salads, and green-ripe tomato color. The expected flavor is bright, tangy-sweet tomato flavor with a fresh citrus-like edge. Fruit is described as green and about 4–5 oz. Use a tested current recipe for home canning; cultivar name alone does not establish safe acidity.

How to grow Green Zebra
Start Green Zebra indoors about 6 to 8 weeks before the last expected frost. Sow 1/8 in deep in a warm, evenly moist seed-starting mix; expect 6–12 Days near 75–90 °F. Give seedlings strong light, move them into larger cells before they become root-bound, and harden them gradually before planting outside after frost danger.
Plant in full sun with loamy soil near pH 6.0–6.5. Space plants 30 in apart and rows 36 in apart. Maintain moderate moisture, mulch after the soil warms, and keep foliage off wet soil where possible. Set up stake at transplanting. The indeterminate plant reaches 73–96 in.
Season care
• Give Green Zebra strong light from emergence so seedlings remain stocky rather than stretched. • Install stake when transplanting; adding support after vines are large can damage roots and stems. • Water at the soil line and maintain even moisture to reduce cracking, blossom-end rot risk, and stress-related fruit problems. • Harvest when the fruit has reached its cultivar-specific color and gives slightly to gentle pressure; color alone can be misleading on green, purple, or striped varieties. • Use 70-79 Days as a planning range rather than a guaranteed calendar date; weather and transplant stress can shift first harvest.
Harvest and maturity
70-79 Days from transplanting under suitable conditions. Harvest when the cultivar-specific color has developed and the fruit gives slightly to gentle pressure; green-ripe, striped, purple, and dark cultivars require more than a simple red-color test.
Saving seed
Tomatoes are primarily self-pollinating, but occasional crossing can occur. To maintain Green Zebra, save seed from several healthy true-to-type plants and bag unopened flower clusters when extra isolation is needed. Allow labeled fruit to ripen fully, squeeze the seed and gel into a container, ferment briefly until the gel releases, rinse clean, and dry the seed in a thin labeled layer. Store the finished lot cool and dry with the year, source, plant count, and isolation notes.
Common questions
When is Green Zebra ready?
Plan around 70-79 Days. The listed range is a planning guide, and weather, transplant stress, and harvest stage can shift the actual date.
How long does germination take?
Expect 6–12 Days near 75–90 °F. Cooler media, excess water, old seed, or uneven moisture can delay emergence.
How large does it grow?
Expect about 73–96 in. Growth habit: Indeterminate. Support: Stake.
How is it used?
Fresh slicing, salads, and green-ripe tomato color
Can I save seed?
Tomatoes are primarily self-pollinating, but occasional crossing can occur.
