(Also known as Porterhouse), these plump beefsteak tomatoes weigh from 0.9?1.4 kg each, with even larger fruit possible under ideal growing conditions. The fruit are bursting with larger-than-life flavour. The luscious flesh is just the right balance of meaty solids and succulent juice. Indeterminate (1.7 – 2m in height)


Due to its size it is best grown under glass in the UK allowing it a longer period to fully ripen and will need slightly greater spacing between plants. 


  • Sow in early spring 1/16 inch deep.  Germination takes around 6-14 days at 65-75F.
  • Transplant the seedlings when large enough to handle into 3 inch pots.  Grow on under cooler conditions and when about 8 inches tall,  position in the greenhouse  and plant out 24-36 inches apart.
  • Provide support and tie in regularly.  Remove side shoots and restrict the plant to one main stem.  In late summer remove the growing tip to hasten ripening.
