Merveille De Quatre Saisons Lettuce (Heirloom, 49 Days)

Heirloom. A truly marvelous lettuce. It was the only lettuce in our trials that remained good tasting during a very dry, hot summer and continues to impress us each year. Bibb type leaves are wavy and light green with a red overlay. Forms a loose 12” head with meaty texture and fine flavor. 

500 seeds


Germination: 4-10 days

Germination Temperature: Optimum soil temperatures 60-75 degrees F. Soil above 75 degrees F inhibits germination.

Seed Sowing Depth: ¼ inch deep

Outside Sowing: Spring when soil temperature reaches at least 50 degrees F. Sow 1” apart, thin to 6-12”, depending on the size of lettuce you want, baby to full heads. Keep soil moist during germination. Sow every 2-3 weeks for a longer harvest period. Sow heavy seeded rows every 10-14 days for baby greens using the 1 oz. Pinetree Lettuce Mix.

Starting Indoors:  3-4 weeks before planting outsideSow 2-3 seeds per cell/pot, thinning to one per cell/pot. Provide 60-70 degrees F soil temperatures. Transplant out, 8-12” apart in rows 12” apart.

How much does a packet plant: 25 foot single row  

Harvest: Cut whole heads at base or snipe off individual leaves.  

Tips: Lettuce needs fertile soil for optimum growth. Work in compost or well rotted manure into your soil before planting. Provide adequate, even moisture for the best growth. Mulching helps retain moisture.

4 seasons lettuce

This lettuce was wonderful! We had a very wet, cold spring and I planted it out in my cold frame. It surpassed my expectations; I plan to plant it again for fall. Great taste and wonderful color. I enjoy shopping at Pinetree - service is great, and the product variety is awesome.

Excellent lettuce for cool weather

This lettuce came up quickly, and has been going strong even through light frosts here in the Southwest in January. I haven't even had to cover it! The flavor is excellent, the texture is nice too. I will definitely be growing this in my winter garden again.

Soft leaves, full of flavor

We had good luck with these seeds and the lettuce is hearty and flavorful. A bit more bitter than your typical lettuce, very soft leaves.

Long Producer and Delicious!

We're eating the last delicious leaves of this lettuce this week. It's started to bolt and, as it's an heirloom, I'm going to gather some of its seed. Highly recommend this one.
