When Europeans first arrived in the Canberra area, it was said that the open hillsides glowed yellow with yam daisy flowers - a delicious indigenous staple food. This little yellow flowered plant looks remarkably similar to a dandelion, but up close it is quite different.

Sadly today yam daisies are quite hard to find. Decades of sheep grazing has almost eradicated this plant from its former habitats. The yellow flowers you see around the suburbs, and increasingly in our national parks, are usually exotic dandelions and cat's ears.

So next time you're walking through the bush and you come across a yellow flower, how can you tell if it's really a yam daisy?

In this post I'll show you how.

Permaculture is about growing plants together in beneficial combinations - where the characteristics of one plant benefit another, and vice versa. A simple idea is to ensure you have habitat for pollinating insects (e.g. lots of different flowering plants) so you can be sure there are lots of the right kinds of insects around to pollinate your fruit trees when they come into flower too. Another is to use ground covers that don't directly compete with your trees and shrubs, but instead act as a barrier to weeds and grasses especially, which can compete for nutrients in the same soil layer with establishing produce trees.
