A coloured variant of sucrine lettuce, Red Sucrine combines the typical sweet, sugary taste with red-edged leaves, giving it an even more eye-catching look in salads.
It belongs to the species Lactuca sativa var. capitata, family Asteraceae. A small, compact, elongated heart-shaped head, with oval light green basal leaves edged in red.
Sow from February to July for a staggered harvest from May to October, keeping plants about 30 cm apart after thinning.
It prefers loose or medium soils with good water availability; soil rich in organic matter favours both head development and the intensity of the red colouring.
Sun exposure intensifies the red colouring of the leaf edges; regular watering keeps the leaves turgid and crisp until harvest.
Like the white variant, it needs protection from slugs and snails in the early stages; aphids and downy mildew can appear in overly humid conditions.
The colour contrast between the green leaves and red edges makes it particularly prized for mixed salads with a neat, colourful appearance.
Besides the typical properties of lettuce, the reddish colouring of the leaf edges indicates the presence of anthocyanins, antioxidant compounds that add to vitamins A and C.
Per 100 grams, Red Sucrine butterhead lettuce provides about 15 kcal, 1.2 g protein, 2.1 g carbohydrates, 0.2 g fat and 1.3 g fibre. Good source of vitamin A and anthocyanins.
