Parris Island forms 25-30 cm (10"-12”) heads of slightly savoyed, dark green leaves with a creamy yellow white heart.

Planting Instructions:
  • Lettuce seeds require light to germinate; hence they must be sown just barely below soil surface in full sun.  Direct sow lettuce seeds or start indoors and transplant when the risk of frost has passed.  Work soil loose and sow lettuce seeds 2-3 seeds at 5mm-12mm (¼-½") deep and barely cover with soil medium.   Lettuce seeds will not germinate when soil temperatures exceed 30°C, (87°F) and do best when soil temperatures remain between 15 to 20°C, 59 to 68° F.  Thin to space seedlings to 30cm (12") apart. Space or thin loose leaf varieties to 15cm (6”) apart.  Row spacing for all lettuce types should between 30-40cm (12-16”) apart.  
  • Soil Conditions:  Well worked rich, loose well-drained soil. Ideal pH: 6.5-7.0..
  • Planting Depth:  Sow Lettuce seeds at 6mm-12mm (¼-½") deep. Lettuce germination requires sunlight.  Surface sow seeds and barely cover with soil medium.

  • Days to Maturity:   21 days for leaves.  77 days for heads.  
  • Watering: 2.5 cm (1") of water a week ensures good growth. The amount of rain that falls during the week affects how much you should water your garden.
