Day 292: Both Sulphur Cinquefoil (Potentilla recta) and Spotted Knapweed (Centaurea biebersteinii) were introduced to North America from the Eurasian continent. In the absence of the species which consume them, they spread quickly and sometimes crowded out native species. Both plants shown here grow in dry disturbed soils such as those found along roadsides and in vacant lots. Beautiful to look at, but it's a skin-deep beauty. If you see these, pick a big bouquet for your table or better yet, pull them up by the roots.
