Helianthus is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of Helianthus are native to North America and Central America. The best-known species is the common sunflower. This and other species, notably Jerusalem artichoke, are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species H. annuus typically grows during the summer and into early fall, with the peak growth season being mid-summer.
Tiarella cordifolia, the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name cordifolia means "with heart-shaped leaves", a characteristic shared by all taxa of Tiarella in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort.
Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. As of October 2022, the taxonomy of Tiarella in eastern North America is in flux.
Nabalus albus, the white rattlesnake-root, also known as Boott's rattlesnake-root or white lettuce, is a plant in the family Asteraceae, native to Canada and the Eastern United States. Details of the flower heads are needed to separate this species from others in the rattlesnake-root genus (Nabalus). The Iroquois applied a poultice of the roots of white rattlesnake root to rattlesnake bites. It can be found growing in forests, woodlands, and anthropogenic habitats. The flower head has ray flowers only, meaning all of the individual flowers of the flower head have a strap-shaped ray, which may or may not have teeth at the very tip of the ray. The colors vary from blue to purple, pink to red, or white. The leaf blade length can be between 40 and 300 mm. while the flower head width can be 3 to 5 mm. Blooms from July to September in Missouri. In 2010 it was reclassified from the genus Prenanthes to Nabalus.

Because of this, it is considered a globally rare species, with only 35-70 remaining populations. Much of its natural habitat of prairie and savanna has been destroyed. In 2010 it was reclassified from the genus Prenanthes to Nabalus.
