Nitrogen fixing plant species suited to temperate climate such as North Canterbury New Zealand
Nitrogen is an essential element for plant growth. Certain plants have a useful ability to capture nitrogen from the atmosphere. This is often achieved through symbiotic relationship with fungi in the root zone. Being able access unlimited nitrogen allows these plants to grow quickly while also making some available to surrounding plants. The practical reality is that including nitrogen fixing plants of various shapes and sizes amongst other productive plantings improves overall health, vigour and fertility,

Juglone tolerance
Choosing suitable companion plants for walnuts is difficult because these trees are alleopathic, secreting a substance called juglone that suppresses competing plants. There are very few species that grow well and thrive under the canopy of a walnut tree or in close proximity to its roots. This list details a number of useful species that apparently tolerate walnut juglone.
