Dandelion

Taraxacum officinale Weber

The dandelion plant is a beneficial weed, with a wide range of uses, and is even a good companion plant for gardening, but is often thought of solely as "bad". It has been described as "a plant for which we once knew the use but we've forgotten it". However, its ability to break up hard earth with its deep tap root, bringing up nutrients from below the reach of other plants, makes it a good companion for weaker or shallower-rooted crops. It is also known to attract pollinating insects and release ethylene gas which helps fruit to ripen.

Dandelion leaves contain abundant amounts of vitamins and minerals, especially Vitamins A, C and K, and are good sources of calcium, potassium  and fair amounts of iron and manganese, higher than similar leafy greens such as spinach.

So easy to grow, Dandelion grows like a weed!! Sorry, I thought that was funny.....
