Hypericum olympicum
This plant is kept in the atlas for identification and safety, not for use. Read the safety notes below before handling it, and keep it away from children, cats, and food.
Olympic St. John's Wort has never carried the herbal reputation of its famous relative, Hypericum perforatum. It belongs to the same golden-flowered genus, but its own story is a horticultural one rather than a medicinal one. European plant collectors brought it down from the rocky heights of Greece and the Balkans in the nineteenth century, prized purely for its cheerful, sun-colored blooms and its willingness to thrive where little else would grow. Rock gardeners have treasured it ever since as a tough, low mat of gold for the hottest, driest, stoniest corners of the garden.
Safety.
This species is ornamental only, not the St. John's Wort used in supplements (Hypericum perforatum), and should not be ingested. Like related Hypericum species, it can cause photosensitivity in grazing animals that eat large amounts.
