Days to Maturity: 45 from direct sow This ingenious Sow Effortless Collection™ Organic Tricolor Romaine Blend lets you easily grow exactly what you need for the perfect salad. This collection is cool season and can tolerate a slight frost. Lettuce and greens are best started outdoors as soon as the soil can be worked in early spring or late summer (for a fall crop). For those living in zones 8 and warmer, sow your seeds in early fall for a winter harvest. Using our Sow Effortless Collection™ Organic Tricolor Romaine Blend Seed Tape means succession planting is easy and every seed is used efficiently. Small seeds are trouble-free because they are pre-sown in biodegradable tape you place directly on the soil. Simply sprinkle to cover with soil and water them in. As long as the temperature stays below 80 degrees Fahrenheit, you can keep making successive sowings—every two weeks is typical—to extend your harvest. As summer approaches, however, you will want to plant varieties that tolerate heat and resist bolting (producing flowers and seeds too soon). Sow Effortless Collection™ Organic Tricolor Romaine Blend Seed Tape Includes: Lettuce Vivian: a dark green romaine for bunching with baby leaves. It has a vigorous growth habit and is quick to produce. Delicious medium green leaves can be picked at a smaller size for a variety of leaves. Lettuce Silvia: a beautiful red romaine for all year sowing. It is a dark foliage lettuce with smaller leaves and a sweet flavor. They have a looser head and soft yet crisp texture. Lettuce Brun de Hiver: a bronze romaine with green colored stems and lover leaves. Has a unique foliage with mixed colors. These colors are lettuce, orange and a soft pink. The edges of the foliage changes. This lettuce has large heads and is a great grower. You've never planted seeds more easily than with our Sow Effortless Collection™ that includes, in addition to tapes, mats, discs, and kits that have the seeds included, simply place them in the garden, lightly cover with soil, water regularly and enjoy. The tapes dissolve over time from watering. Includes: 15 feet of seed tape
