Leafy hawkweed

A good plant for rock gardens, it has broad, woolly grey leaves and yellow daisies in summer. It self seeds but isn't a problem. The soil must be on the poor side with plenty of added grit to guarantee good drainage. It's not the showiest plant you'll ever see, but has a quiet background charm for more up-front performers. The similar H. villosum is a very good alternative, while H. spilophaeum has nice chocolate-spotted leaves.
