Eryngium 'Blue Hobbit' is a dwarf Eryngium planum hybrid. What a break through in breeding. masses of bright electric blue thistle flowers on a 12in plant. An excellent clump former. Easy and unfussy in the sunny herbaceous border. Easily a hundred flowers on a 2year old clump in garden. We sell these in full flower on a 3litre pot at Hampton Court Flower Show, they just walk away from the stand!
