In the garden, Cenolophium denudatum is a good plant to grow if you want to attract helpful insects to your garden, especially bees. It is a very easy plant to grow, largely due to its vigour, and has long-lasting looks.

Plant as part of an herbaceous border or in a wild or low maintenance garden. In addition to its ornamental features it looks great as part of dried flower arrangements.
