Crisp Mint Lettuce (60 Days)

The search for a lettuce that tolerates the hot months of summer could be over for you. We have always loved Jericho but this has proven to be a worthy rival. The ruffled mint colored leaves are crisp and sweet even in elevated temperatures. Young heads are rather open but tighten up as they mature, growing to a sturdy 10”. Harvest mini or full sized. Experiment by growing this as a cut and come again lettuce, (we discovered this is possible thanks to our resident groundhog).

500 seeds


Germination: 4-10 days

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

Outside Sowing: Spring when the 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 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 the 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.

Very Nice Lettuce

I found this lettuce prefers only a few hours of sun a day in my area, zone 5. I have them in a container. I pick some for a salad almost every day.

I recommend this product

My favorite, not bitter, grows strong.

I grew 5 different lettuce varieties and the crisp mint romaine was my favorite. The germination rate was awesome. The flavor is great. I planted April 1, it was the first lettuce to sprout and we have been harvesting all through the month of May and continue to have a healthy harvest even though it is June in the desert and the temperatures are in the 90s. It has not had any bitterness to date, which is why I wanted to try it. I'm so pleased. We planted the heads close together and snip the leaves after they get 3-5 inches tall and the plant grows more leaves. Love this one.
