5-26 Yarrow, Multiflora Rose, Alsike, Blue Flag Iris, Bittersweet Nightshade

5-26 Yarrow, AKA Milfoil, is a common white - or pink - flower of fields and roadsides.

Once widely cultivated, Multiflora Rose is now a troublesome invasive escape.

The sweet smelling pink flower heads of alsike Clover, an alien escape, are open.

Blue Flag Iris is coloring marshes and wet meadows.

The dangling violet, shooting star-shaped flowers of Bittersweet Nightshade drape moist thickets. John
