Solanum lycopersicum

  • Prolific heirloom with abundant harvests.
  • Rich, full flavour balanced by gentle acidity.
  • Early, reliable fruit set in cooler conditions.
  • Firm, lightly fluted fruit with excellent crack resistance.
  • Vigorous indeterminate plants with excellent disease resistance.

This productive heirloom combines outstanding flavour with exceptional garden performance. Vigorous indeterminate plants produce abundant crops of attractive, lightly fluted tomatoes with rich, full flavour balanced by a pleasant touch of acidity.

One of its greatest strengths is its ability to set fruit early and reliably in cooler conditions, making it an excellent choice for regions with mild summers or cool spring weather. The firm skins resist cracking, while the plants show excellent disease resistance, ensuring dependable harvests throughout the season.

Equally suited to home gardens and market growers, this is a reliable heirloom that rewards gardeners with heavy yields of beautiful, flavour-packed tomatoes.

TRANSPLANT (recommended) – Start transplants 5- 6 weeks before planting date. Sow seeds 6mm deep, 4 seeds/2.5cm. Lightly cover. Keep mix at 23-28°C. Pot up into 5cm or larger cells after first set of true leaves appear. For growing transplants, maintain temperature at around 22°C during the day and 18°C at night

Harden off plants by slightly reducing temperature to 15-18°C and reducing water for 2-3 days before transplanting.

NOTE - Don't start too early—leggy, root-bound, or flowering transplants can cause stunting and reduce early production. Avoid exposing unprotected plants to consecutive nightly temperatures below 7°C.
