Introducing Warrigal Greens

Warrigal greens are native to large parts of the Asia-Pacific region and also Chile where they grow along beaches and in dunes

This herb is a favourite for the veggie patch. In New Zealand, they’re called New Zealand spinach, and here in Australia, you might hear them referred to as native spinach or Botany Bay spinach. 

Warrigal greens are native to large parts of the Asia-Pacific region and also Chile where they grow along beaches and in dunes. These greens are hardy which makes them ideal as a leafy green ground cover for areas with sandy soils.

This plant will happily crawl across the ground but can also climb a short trellis if you give it one. In addition to being a fantastic ground cover, this plant act like a living mulch that keeps the surface of the soil cool in the heat of summer.

This plant are known for being drought resistant and heat tolerant and are grown for their succulent green leaves which can reach about 15cm in length. Most of the plant is edible so there is very little waste.

The herb apparently gets its name from its seeds. It has been said that warrigal greens are named because the seeds look like puppies’ heads and warrigal is the Wiradjuri word for dog. The botanical name of Tetragonia refers to the woody seeds that are ten-sided.

Features of New Zealand Spinach

Warrigal greens have soft stems and leaves, and the plant can reach a height of 20cm, but can spread up to 2m. The leaves are fleshy and covered with tiny hairs that give it a glow in sunlight. Small green-yellow flowers pop out at the base of the leaves in spring and summer. 

Once the flowers are fertilised, they become a green pod with horn-like growths. As the seeds mature, they turn brown and the small horns dry out into sharp spikes. You can collect the seeds from the plant once they have turned brown and come off the stem when touched.

This plant are native to coastal areas of Southern Australia. We love it because it’s one of the easiest native food plants to grow. This herb is tolerant of wind and a variety of soil types, and can grow quickly – average size is about 2 m across and around 20 cm high.

This herb can live long in temperate areas, loves full sun and also well-drained soil. They can handle sea-spray in coastal gardens and seldom deal with disease or pests. 

When planted in the garden, this ground cover will keep soil moisture levels and temperatures consistent. Warrigal greens do well under shallow rooted trees that don’t like competition, as they have a small root system.

If you live in an apartment and want to add to your balcony garden, you can plant warrigal greens in a hanging basket. Just keep an eye on it – this plant might be overly enthusiastic and spread over other smaller plants.

Growing Warrigal Greens from Seed

Botany bay spinach can be grown easily from seed in spring time. They grow quickly and abundantly through spring and summer. First, the small yellow flowers appear, followed by the funny looking seeds.

Let the seeds become brown and woody before collecting them for the following year. You can further dry seeds in a paper bag and then store in a dark, cool, dry cupboard until the following spring. 

You’ll need to soak the seeds overnight in warm water before sowing them – they need to be 10mm deep and 50cm apart. You can also sow them in a medium to large pot or in trays indoors, to be transplanted in the garden at a later stage.

Growing Warrigal Greens

Soil temperatures of 18-35 degrees Celsius are best. Germination takes between one to three weeks as long as the temperature is above 25oC. Botany bay spinach like to spread out so be sure to give them enough space. 

The plant should be kept moist but don’t over water it, and add mulch to preserve moisture. If you’ve prepared the soil well then you don’t need to fertilise at the start of the growing season.

You should pick the leaves frequently to encourage more growth. If you see the lower leaves turn yellow you can just remove them. Harvesting of the leaves is 50 days from sowing the seeds.

Sowing Warrigal Greens Seeds According to Climate

If your region has a temperate to warm temperate climate, you can sow seeds into trays at the start of spring, and then transplant your warrigal greens into a full sun position in the garden after the last frost. 

For regions with subtropical climate, sow warrigal greens seeds into trays at the start of the last month of winter and then transplant when the last frost has passed.

Direct sowing them into a sunny position in late winter also works well if you don’t get any frost issues. Warrigal greens do struggle through hot subtropical summers if grown in full sun, but will thrive if grown in a moist, shaded spot. 

If your home region climate is tropical, then Botany bay spinach are best sown in mid-autumn and grown through winter. It’s best to plant them somewhere they will be shaded through summer to maintain active growth.

Sun Requirements

Botany bay spinach enjoy a dose of full sun but can also grow in part shade if you live in a region with a tropical climate.

Best Soil Type for Warrigal Greens

Warrigal greens are very hardy and can survive harsh conditions and poor soils.  This herb will however bless you with large, lush greens for harvest if you show them a little love. Give this plant free-draining organic-rich soil for best results.

Watering Warrigal Greens

Although they are a drought hardy plant, warrigal greens will do better if they are regularly watered. If the plant does go through a period of little water, just give it a trim back and a good watering to stimulate new growth. 

What Fertiliser to use

Warrigal greens can be fed with a top layer of compost or handful of slow release organic fertiliser halfway through the growing season. If your plant is in a container, feed it with organic based liquid fertiliser every few months to help maintain healthy production.

Having the right tools and products to care for your garden makes a big difference (and make the whole gardening experience more enjoyable). We understand the need to have honest and in-depth product and equipment reviews, so you can make the right decision.
