Lactuca sativa

We’ve blended seeds for an emerald-green baby butterhead with softly folded leaf rosettes together with a lovely, deep-red, ruffled and crispy mini leaf lettuce. This glowing duet makes a beautiful tapestry of contrasting colors, textures and shapes. Both heat tolerant varieties make compact 5 to 6 inch heads at maturity. A feast for the eye and scrumptious to eat over a long harvest period, this duet is pretty as a picture in the garden or in big pots on a patio or deck.

In cool spring weather, start seeds in full sun. Sow seeds 1/4 in. deep and 1 in. apart in fertile, well-drained soil mix. After the seedlings germinate and begin to grow, it's important to thin the young plants so they have room to mature into heads. Thin seedlings when a few inches tall to a final spacing of 5 in. apart so they have room to mature into full heads (extra seedlings will transplant easily to grow elsewhere). Plan on 9 -11 full heads in a 16 - 18 in. pot or a 9 x 12 in. window box. Plan on 3 full heads in an 8 in. pot.


Lettuce thrives in cool conditions. Be sure to thin properly and keep evenly moist for sweet tasting, full heads. For a constant supply, make several sowings a few weeks apart until summer weather turns hot. Plant again in late summer for fall harvest. In hot weather, give lettuce some afternoon shade and check water daily. Feed with liquid fertilizer every 2 weeks. Try setting seedlings around the edges of a big pot holding a young tomato or pepper plant. Harvest the lettuce as the bigger plant grows to need the space. 


Savor young lettuce thinnings in your first spring salads. Then harvest plants by cutting mature heads when they feel firm and well-filled out. Pull and discard or compost over-mature plants if they begin to elongate ("bolt") in hot weather as leaves turn bitter at this stage.
