Lettuce 'Jadeite'
Lettuce 'Jadeite'
Lactuca Sativa
Bigger than a gem romaine with a looser but still bleached blonde heart, Jadeite has a unique matte apple green colour. Described as having a juicy, delicately crunchy texture and a flavour profile enhanced by salt. Easy to clean while still having a conical shape that yields the more buttery heart. Good heat and cold tolerance – given Winter protection, this is a superb all-season variety.
Bred by Frank Morton from a cross between ‘Winter Density’ and ‘Dark Green’ Romaine. Downy Mildew resistant.

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.
