Hieracium glaucinum, a European hawkweed, is a low-growing perennial wildflower that produces cheerful yellow dandelion-like blooms in partial shade to dappled woodland edges. It is a hardy, self-sufficient plant that requires minimal watering once established and grows well in average to poor soils. Best suited to naturalized garden settings or wildflower borders, it can spread readily and is rarely available through commercial nurseries.
