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.
