‘Sweet Valentine’ romaine lettuce, ecologically grown seeds

Lactuca sativa

Product code : GAIAS-0273

Upright heirloom romaine with crisp tender leaves and sweet flavour. Good heat tolerance; maturity in 60 to 75 days. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots.

‘Sweet Valentine’ romaine lettuce, ecologically grown seeds (Lactuca sativa) This open-pollinated heirloom forms upright heads of crisp tender leaves with sweet flavour. Gaia highlights its good heat tolerance, which is useful when summer temperatures challenge many lettuces. Its vertical habit simplifies care, improves access to leaves, and suits garden beds, raised plots, and large containers. Leaves are well suited to salads, sandwiches, wraps, and fresh garnishes. The packet contains 100 ecologically grown seeds; Gaia does not identify this product as certified organic. Sweet Valentine combines romaine texture with greater reliability during warmer periods.

Direct sow as soon as soil can be worked, 1/4 to 1/2 inch deep, or start seed indoors three to four weeks before planting out. Maintain the medium at 12 to 21°C, optimally 16 to 18°C; germination generally takes 7 to 10 days. Although Sweet Valentine tolerates heat better during growth, most lettuces germinate poorly above 25°C. Space plants approximately 6 inches apart and rows 12 to 18 inches apart, or up to 24 inches where a wider irrigation or harvest aisle is needed. Thin carefully so upright heads have light and airflow.

Grow Sweet Valentine in sun or light partial shade and fertile, cool, well-drained soil. Maintain even moisture to keep leaves tender and limit bitterness. Maturity occurs in 60 to 75 days. Upright heads reach approximately 8 to 12 inches in both height and width and tolerate temperatures near −7°C. Harvest outer leaves as needed or cut the entire romaine head. Gaia indicates that flavour is especially pleasant after a few cold nights. Keep clean dry leaves refrigerated and use them promptly for crisp texture. Succession sowings can extend harvests from spring into early autumn.
