Notes:There are about a dozen species of Dragon-head in North America, but only Physostegia virginiana shown here is indigenous to Ontario. This species is also the only one that you are likely to find on sale in a nursery. It occurs naturally over a large part of North America along river banks and wet meadows. In moist rich soil, this plant can be somewhat invasive and will need cutting back unless you buy a cultivar like "Miss Manners" which is more clump forming.
