New Zealanad Spinach Not a true spinach, but just as tasty. Can be grown in hot, dry conditions. Very difficult to germinate, advanced grower level.
Etragonia tetragonioides is a New Zealanad native spinach that loves the beach, growing in sandy soils and enjoying salty winds, as well as being very heat tolerant. This plant is perfect for the deepest southern parts of the USA. Tastes excellent lightly steamed.
New Zealand spinach has odd-looking seeds, shaped something like a cross between a spikey pillow and a manta ray. Purchase some and sow them in the springtime, or nearly throughout the year in Florida.
Sow New Zealand spinach ½ inch deep and 2 to 4 inches apart. New Zealand spinach grows from seed clusters that produce several seedlings, similar to beet seed. Soak seeds overnight in water to speed germination. When seedlings are 3 inches tall, thin to the strongest seedlings, from 12 to 18 inches apart. Set New Zealand spinach in hills similar to squash. This will allow the weak-stem to sprawl. Space hills or rows 24 to 36 inches apart.
