?Handsome in flower and among the hardiest? (Wyman); from rocky open woodlands of Quebec and Michigan, this tough 3' shrub produces its bright-yellow 1" flowers in mid-summer. S-PSh/M-D

There aren't many broadleaved evergreens native to the Great Lakes Region, but this is one of them, and a very nice one as well. Forms a tidy 2-3 foot shrub, and in late summer smothers itself with standard hypericum flowers ? five rounded yellow petals surrounding a central poof of long, bright yellow stamens. Extremely tough and easy. Zone 4
