May need some support, as it gets quite tall. I question why the description lists "all parts" as poisonous - I've never found anything in my books to suggest so, and the root is used often in herbal concoctions.

I found elecampagne growing in seasonally damp, full-sun areas of my property when I moved here. The huge, somewhat silvery first-year leaves are the real star, with the yellow second-year flowers being a bonus. This is not a neat and tidy plant, but it would make a striking addition to an herb garden or informal border. During wet years, they can easily grow 6 feet tall and 3 feet wide. If you live in a cool climate and plant them in a sunny, damp location, give them plenty of room.

My information says that it is hardy in zones 3-9 and can tolerate partial sun. I have found that it is very hardy and, for me anyway, drought tolerant. Last year we had severe drought and I never watered it. I tried moving it and left some of the root by accident. Despite this abuse and neglect, it still came back.

This plant gets very high, so only from a distance you can see that it is flowering. The leaves more down are huge also..I've measured them 100 cm easy..sometimes I rip one leaf off to use it as a shelter in a suddenly rainfall.. It can take more drought than expected...

I love the beautiful bright orange/yellow blooms. Great accent plant for mid to back of border. Very drought tolerant. Easy to grow. Spreads moderately.

This is a tall dramatic plant that can reach a height of 8 ft. and has showy daisy type blooms. The leaves are broad with downy gray undersides, and can be over a foot long. Plants bloom in mid summer with numerous shaggy yellow flowers. The thick rhizome has a long history as an herbal expectorant and is used today in treating coughs, asthma, and flu
