1) Onopordum acanthium aka Scotch Thistle
We had about 150 visitors to the garden yesterday for the Monadnock Region Garden Conservancy Open Day. It was a hot, sunny day with a refreshingly pleasant breeze. The most asked about plant in the garden was the enormous Scotch Thistle, Onopordum acanthium. This biennial is a favorite of mine because it has a such a commanding presence in the garden. When it goes to seed, it becomes ratty looking and I immediately take it out. It needs to be removed carefully because the spines are razor shape. For some people it is an intimidating plant but for me, at 6 foot three, it is one of the few herbaceous plants that I can look up to.
