Stem erect, solitary, upper panicle branched, all stem branches white. Basal and lower stem leaves large, undivided, oblanceolate, elliptic or elliptic-oblanceolate, 6 to 15 centimeters long, 1.5 to 6.5 centimeters wide, apically acute, shortly acuminate or rounded, sessile, base cordate or sagittate-semi-amplexicaul, margin undulate or finely serrate, tapering upward, homomorphic or lanceolate with the basal and lower stem leaves, the leaves of the lower panicle branches and the leaves on the panicle branches very small, ovate-cordate, sessile, base cordate or sagittate-amplexicaul, margin entire, all leaves glabrous on both surfaces.

Heads numerous or very numerous, arranged in panicles at the tips of stem branches. Involucral bracts ovoid at fruiting stage, 1.1 cm long, 6 mm wide; involucral bracts 5-layered, outermost broadly triangular, ca. 1 mm long, ca. 2 mm wide, outer triangular or lanceolate, 5 to 7 mm long, ca. 2 mm wide, middle lanceolate to ovate-lanceolate, ca. 9 mm long, ca. 2 to 3 mm wide, inner linear-oblong ellipsoid, 1 cm long, ca. 2 mm wide, all involucral bracts acutely pointed apically, glabrous outside.

Growth habit

Lettuce like cool environment, neither cold hardy, nor heat resistance, the growth of the appropriate temperature of 15 ℃ to 20 ℃, 90 to 100 days of fertility. Seeds are more resistant to low temperatures, can germinate at 4 ℃. Germination temperature 18 to 22 ℃, higher than 30 ℃ when almost no germination.

Plant growth period, like cool climate, 15 to 20 ℃ growth is optimal, high yield, excellent quality; sustained higher than 25 ℃, growth is poor, leaf quality coarse old, slightly bitter taste. But cold hardiness is also quite strong, 0 ℃ or even short-term sub-zero low temperature on the growth of no great obstacle.

Lettuce root system is developed, the leaf surface has waxy, drought tolerance is quite strong, but cultivated in fertile and moist soil, high yield, good quality.

Soil pH of 5.8 to 6.6 is suitable.
