70-90 Days – 25 days to baby leaf harvest.
Silvia is a dark wine-colored Romaine Lettuce with elongated, spoon-shaped leaves. Fast growing, Silvia goes well in containers and performs great in microgreens harvesting.
High in Lycopenes, antioxidants and of course, Vitamin A. Silvia is better adapted to high temperatures than most lettuce, but is still likely to bolt if exposed to temps over 90 F for more than a week or so.
In the West, especially in the Great Basin and lower deserts, Silvia is best grown in early spring and late fall. Full sun and cool temperatures will intensify the burgundy color, and these conditions are desired for a full range of flavor.
Shading and high temperatures will inhibit the red pigmentation and produce more of a bronze color and green fading. Romaine and Cos type lettuces create dense, elongated heads.
Easily sown and grown at temperatures as low as 45 degrees, yet able to withstand short warm periods up to 90+ without going to seed.
