Green Giant
Green Giant is an indeterminate heirloom beefsteak with smooth chartreuse green fruit. It ripens in about 87 days.
Potato-leaf foliage

Flavor
Described as very sweet and fragrant with fruit aromas, a complex sweet-and-spicy character that growers call rich and well-balanced. As with every flavor note here, this is the recurring catalog and grower description, not a measured claim.
Origin
A German heirloom discovered and stabilized by collector Reinhard Kraft, who shared seed with North Carolina gardener Craig LeHoullier around 2004.
What it does well
- Large green beefsteak with rich, sweet, spicy flavor
- Sturdy potato-leaf indeterminate plant
- Smooth fruit that resists cracking
Where it frustrates
- Hard to judge ripeness since it stays green
- Long season to maturity
Growing it
- Indeterminate vine. It keeps growing and setting fruit right up to frost, so plan on a tall stake or cage and regular pruning through the season.
- Late to ripen, past 80 days, so it wants a long warm season or a head start indoors.
- A moderate grow, no special tricks but worth steady attention.
- Wants real summer warmth and is slow to set when nights stay cool.
- Skins resist cracking, even after a heavy rain.
Disease resistance
An heirloom, sold without formal disease-resistance codes.
Why no hardiness zone?
Tomatoes are warm-season annuals, so variety choice comes down to days to maturity and your local frost dates.
