Crisp and reliable romaine lettuces, perfect for continuous harvests in Quebec!
Romaine lettuce is a must-have in the vegetable garden: crisp, fresh, easy to grow , and perfect for salads. At Semis de la Seigneurie, we offer two complementary varieties: Parris Island (a classic romaine, larger, very productive, and tolerant) and Little Gem (a compact mini romaine, portion-sized, ideal for pots). Together, they provide extended harvests from spring to autumn, even in zone 4b .
Why choose Parris Island & Little Gem romaine lettuces from Semis de la Seigneurie?
✅ Seeds produced in Quebec – Adapted to zone 4b, pesticide-free
✅ Two complementary formats – Large romaine + mini romaine “portion”
✅ Very crunchy – Firm texture, sweet and fresh taste
✅ Fast harvests – Ideal for staggered sowing throughout the season
✅ Perfect for gardens and pots – Containers, balconies, vegetable gardens

Culture in Quebec (zone 4b and above)

Lettuce loves cool conditions. Sow as soon as the soil is workable ( late April to May ) and continue with staggered sowings every 2–3 weeks for continuous harvests. In the height of summer, provide some afternoon shade and keep the soil moist (mulch + regular watering) to limit bolting. In autumn, cool nights make romaine lettuce even sweeter and crisper.
Producer's advice
💚 Staggered sowing = lettuce all summer long (every 2–3 weeks)
☀️ Morning sun + cooler temperatures = best quality in July-August
💧 Constant watering (prevents bitterness and stress)
🌿 Light mulch to keep the soil cool
✂️ Can be harvested as a whole head or as outer leaves
Culinary uses
Roman women are perfect:
  • Caesar salad (incredibly crunchy)
  • Meal salads and sandwiches
  • Wraps and tacos
  • BBQ grilled lettuce (delicious with lemon/olive oil)

🌱 CULTURE

  • Germination temperature: 10–20°C
  • Germination: 5–10 days
  • Depth : 0.5 cm
Transplantation (optional):

  • Exposure: full sun in spring, light partial shade in summer
Interview :
  • Water regularly (soil always slightly moist).
  • Light mulch (fine straw/leaves)

  • Watch out for slugs in spring and aphids in summer.
Harvest :
  • Little Gem : 45–60 days after sowing (mini apples)
  • Parris Island : 55–70 days after sowing (large apples)
