White Avens is a native perennial of dry, upland sites in woodlands. The white five parted flower opens in mid June on a flower stalk that is 12-18" in height.
This is also a native perennial of dry sites in partial shade. The five parted yellow flowers open from the bottom upwards on the flower stalk, starting in mid July.
I featured this native earlier this year as the Plant of the Week.
Found in dry to medium woodlands, its flowers open in late June. Tolerant of quite a bit of shade, it is often found growing right up to the trunks of large trees.
American Lopseed is also a woodland perennial with opposite arranged leaves. The light pink to white 4 parted flowers open in early July. It prefers medium to moist lower lying locations.
Another woodland perennial with opposite arranged leaves. Tiny, white, 2 parted flowers emerge in mid June. This is a common plant of disturbed woodlands, spreading by shallow fleshy rhizomes.
Sweet Cicely is an early flowering perennial, starting around the beginning of May. It is a tall plant, reaching heights of up to 3 feet in good soils. It prefers medium to moist locations but can also be found in drier upland woodland sites.
The 5 parted white flowers are arranged in an umbel.
These are just a few of the many native perennials that produce burs or seeds with hooked hairs.
