I can't resist the shades of red and green in this lettuce mix I have been growing for years. It is the "cut and come again" type where you cut the leaves when young (approximately 2" tall), and it gives you another flush of leaves. In fact, I can usually get three flushes out of this mix.
Aesthetically, they are a beautiful accent in a salad. More practically, I snip and cut this mix to put on my sandwiches or wraps. Most recently, I have been growing these over the winter in the greenhouse and marketing them at the Boston Wholesale Flower Exchange (where retail florists shop.) I sow the seed fairly thickly in a 8"x5" rectangular peat pot. Once the seed is covered lightly with vermiculite, I water, stand back, and watch it grow. They need to grow on for about 3-4 weeks until they are a marketable size.
