Lettuce 'Sweetheart Gem'
Lettuce 'Sweetheart Gem'
Lactuca Sativa
With a flavour described as buttery sweet, this taste test winner is a medium sized, dark green, gem type romaine. But don’t be fooled by its flavour - with it’s mid size upright, blistered leaves and a looser habit while still forming a blanched/bleached heart, Sweetheart Gem shows great commercial grower merit. It holds well in the field (resists bolting) and in polytunnel trials showed resilience against downy mildew.
This was a selection from Wild Garden Seeds ‘Irene Green Gem’ that we have been refining for several seasons. Great four season lettuce - thriving in summer heat over 35C as well as an unheated polytunnel in Southern Victoria winter.

TRANSPLANT - Sow indoors early Spring, 2 seeds per cell, barely covering seeds with fine vermiculite, 3–4 weeks before transplanting outdoors. Thin to 1 plant/cell. Shade the flats on sunny, warm days if necessary to keep the soil surface cool, below 24°C, until germination. Harden seedlings by reducing water and temperature for 2-3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 0°C.
DIRECT SOW - Lettuce is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 16-18°C. Seeds germinate even at low, 4°C, soil temperature, but poorly above 24°C. Sow seeds 2.5cm apart in rows 25-30cm apart. Lightly cover and keep moist. Enjoy thinnings ultimately leaving 25cm between plants. Ample water grows the sweetest lettuce. Careful variety selection is important for hot weather plantings. Sow every 3 weeks for a continuous supply of fresh lettuce.
