Marvel of Four Seasons unfolds into tender, butter-soft heads with a fresh, sweet-green flavor and a delicately crisp bite at the core.

At about 50 days, its rounded, spooned leaves form a lush rosette that stays pleasantly mild and never turns harsh, making it a standout for steady, season-spanning harvests. Grow it for salads and elegant leaf-forward dishes where its velvety texture shines—especially when you want a butterhead that looks as good as it tastes.

Culinary Notes


Chef's Note

A butterhead built for consistency: spoon-soft leaves with just enough core snap to survive a quick toss, without drifting into bitterness. It’s at its best when kept mild—let lemon, olive oil, and a salty, fatty partner (bacon or goat cheese) do the heavy lifting.

Best Uses

  • chilled spring salads where the leaves act like edible “drapes” under vinaigrette
  • leaf-forward sandwiches (think soft rolls) that won’t overpower the filling
  • simple dressed bowls—olive oil + lemon + flaky salt—so the core stays crisp and bright

Flavor Profile

sweet, fresh-green flavor butter-soft leaves with a tender, spoonable bite mild finish that stays non-bitter

Kitchen Pairings

Frequently Asked Questions


What’s the most common problem on Lactuca sativa (leaf lettuce) and how do I treat it?
A frequent issue is downy mildew (often triggered by cool, damp weather), which shows as pale yellow patches on leaves and a fuzzy gray/white growth on the underside. Remove badly infected leaves immediately and improve airflow by spacing plants and watering at the soil line (not overhead). If it keeps spreading, use a labeled fungicide approved for lettuce/leaf vegetables and repeat according to the label.
How often should I water Lactuca sativa during the main growing phase?
During the 40–50 day growing period, keep the top 1–2 inches of soil consistently lightly moist—lettuce roots are shallow and dry spells quickly cause bitterness and bolting risk. Water deeply enough to wet the root zone, typically about 2–3 times per week depending on heat, with more frequent watering during warm, windy weather. Avoid soggy soil; overly wet beds also increase mildew risk.
How do I know when my Lactuca sativa is ready to harvest?
Harvest when leaves are fully expanded but before the plant bolts—most leaf types are ready around 50 days from sowing, though you can start earlier with “baby leaf” cuts. For full-sized leaves, pick in the morning when leaves are crisp and while the outer leaves are the largest and most tender. If the center starts forming a tall stem or leaves turn noticeably bitter, harvest immediately to avoid low-quality heads/leaf flavor.
