This plant entered my yard in a tree root ball that was planted by the home builder. It took a while to find out what it is. It is a weed that is very hard to get rid of. I pull and pull, but so far it is still here. From my research I learned that it can be a pest in nurseries and often gets passed on from them.

I think this plant is very beautiful for people with natural and vast gardens. I saw some very tall specimens growing in a nature reserve area close to where I live. I found them georgeous with the purplish stems and the silvery foliage that set off all the surrounding plants so beautifully. I definitely would grow it if I had the space for it.

Nasty! Nasty weed! This is one of the toughest weeds I've fought. At first I thought it was some sort of Mum. But No! Very difficult to get rid of, or even put a dent into. The leaves smell nice, but that charm wears off after getting to smell it every day as you dig and pull. If you really want to grow this, stick with a container and pluck the flowerheads. I would consider paving your garden before planting this.

This perennial 'weed' is destroying some native grasslands (especially in Long Island,NY). It is difficult to remove by hand (it has underground stems that grow back if left behind), it produces an abundance of seeds, and in my opinion it's flowers are not attractive.

A tall plant with deeply divided dark-green leaves, silvery beneath, and branched clusters of insignificant reddish-brown flower-heads. Common along roadsides, it often has a dusty, neglected look. In ancient times it was believed to have magical properties. Mugwort has many uses, as a herbalist medicine, to repel insects, to flavour ale, or as a herb for stuffing ducks and geese.
