Native Spinach (Tetragonia tetragonoides): The Unsung Hero of My Winter Garden
If there’s one vegetable that’s outshining the rest in my winter garden this year, it’s Tetragonia tetragonoides, or for those who know their Latin, Native New Zealand Spinach. This sprawling, hardy green has become the envy of the patch, thriving with an energy that makes the rest of my winter crops look like they’re still in hibernation.
I was gifted a stack of seed packets for my birthday (by request, I should add), and among them was Native Spinach, a variety I’d never grown before. It quickly intrigued me with its reputation for resilience. And resilient it has been.
Despite heavy July rains and more than one frosty night, this plant has grown with what I can only describe as reckless abandon. Although it’s said to be drought tolerant, it turns out it’s rather water-tolerant too, handling soggy conditions with surprising ease. It has even withstood battering winds, although a few snails have taken an interest, so it’s worth keeping an eye on them.
Unlike traditional upright spinach varieties (like silverbeet or perpetual spinach), Native Spinach sprawls across the garden. It forms a dense mat that looks like it’s taken over, because it has. But it’s also doubling as a living weed mat, so for now, I’m letting it cover the beds until I need the space for spring planting. You can also train it vertically up a trellis, fence, or garden shed wall if you’d prefer a more contained growth habit.
How to Grow Native NZ Spinach
Sow Directly
Plant seeds directly into the soil in late spring or early summer once the soil has warmed. Germination can be slow, so patience helps. Soaking the seeds in water overnight can improve success.
Full Sun to Part Shade
It loves a sunny position but will still grow in partial shade. Well-draining soil is best, although clearly this plant can tolerate a bit of wet too.
Sprawling Habit
Give it room to spread, or encourage it to climb. It can quickly take over a garden bed if left unchecked, so consider where you plant it.
Harvest Regularly
Once established, pinch off the tips regularly to encourage bushy growth and to keep the plant producing tender new leaves.
Watch for Snails
Young plants can be vulnerable to snail attack. A few crushed eggshells or a light sprinkle of coffee grounds can help deter them.
Cooking and Eating
This isn’t a salad leaf. The leaves are slightly thicker and more robust than baby spinach and absolutely need to be cooked before eating. A quick blanch or sauté will soften them nicely. They hold their shape beautifully in stir-fries, soups, or as a side dish with garlic and olive oil. The flavour is mild and earthy—delicious and deeply satisfying.
