Neutral bonehead On Sep 26, 2011, bonehead from Cedarhome, WA (Zone 8b) wrote:

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.

Neutral poppysue On Nov 2, 2001, poppysue from Westbrook, ME (Zone 5a) wrote:

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
