When to plant Warrigal Greens in Arid Australia
Arid zone — applies to Alice Springs, Mildura, Broken Hill, Kalgoorlie, Port Augusta and similar areas. Growing elsewhere? Temperate · Cool · Subtropical · Tropical.
Sow warrigal greens direct from September to November, or through January to March if you can shelter seedlings from the worst heat, dropping seed 5 mm deep. This native spinach substitute is well suited to inland gardens: germination takes 14–21 days, so soak the hard seed overnight first to speed things along. Space plants 30–50 cm apart in rows 60 cm wide and let them sprawl. You will be picking tender tips within 60–90 days. In Alice Springs and Broken Hill it shrugs off dry heat far better than true spinach, which bolts the moment temperatures climb.

Growing notes
Warrigal greens is one of the few leafy crops that genuinely thrives in arid conditions, but it still needs water to stay productive. The plant is a sprawling ground-cover that will run a metre or more across a bed, so give it room rather than crowding it against tidier vegetables.
The main failure here is bitterness and toughness. When plants dry out repeatedly in 40°C-plus heat, the leaves go leathery and the flavour turns harsh. Deep, consistent irrigation two or three times a week, plus a thick straw mulch to hold soil moisture through cold desert nights and blazing days, keeps the tips soft and mild.
A second point worth knowing: warrigal greens contains oxalates, so blanch the leaves in boiling water for a minute and discard the water before eating. Pick young tips regularly, which both improves the harvest and encourages fresh growth. In Kalgoorlie gardens it will happily self-seed once established, popping up the following season with no effort from you. Cut plants back hard if they get leggy and they will reshoot from the base.

Common questions
- Is warrigal greens good for hot dry climates like Alice Springs?
- Yes, it is one of the best leafy greens for arid inland gardens. Unlike true spinach it does not bolt in heat, and as an Australian native it tolerates dry conditions well. It still needs regular deep watering and mulch to keep the leaves tender.
- Why won't my warrigal greens seeds germinate?
- The seed has a hard coat and germination is naturally slow at 14–21 days. Soak the seed overnight in water before sowing to soften it, and keep the soil consistently moist until seedlings appear. Cold soil slows it further, so wait for warmth.
- Do you need to cook warrigal greens before eating?
- Yes. The leaves contain oxalates, so blanch them in boiling water for about a minute and tip out the water before use. After that they cook much like spinach in stir-fries, soups and pies.
- How far apart should I plant warrigal greens?
- Space plants 30–50 cm apart in rows around 60 cm wide. They sprawl widely as ground cover, so err towards the wider spacing if you want to walk between rows without treading on stems.
