Flavor

Described in catalogs as rich, deep, balanced, sweet and tangy, with sweet, full-bodied juice. This is the recurring catalog and grower description, not a measured claim.

Origin

A Ukrainian heirloom from Dnepropetrovsk, named for Soviet cosmonaut Vladislav Volkov, who died during reentry in 1971; brought to North America through the Seed Savers Exchange.

What it does well

  • Productive large red fruit on long vines
  • Won Territorial Seed's Great Northwest Tomato Taste-Off

Where it frustrates

  • Tall indeterminate vines need trellising and sturdy support
  • Sources disagree on days to maturity, listed from 65 to 80 days

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.
  • Mid-season timing, ripening around 70 to 80 days from transplant.
  • A moderate grow, no special tricks but worth steady attention.
  • One of our picks for the cold, short-season gardens of New England.

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.
