Common Tansy - Tanacetum vulgare
This perennial is recognizable by its clusters of button-shaped golden flowers with flat heads, each about ½ inch wide. Tansy leaves are pinnate (feather-like), and separated into smaller leaflets that run along the side of the main leaf stalk, giving them a fern-like appearance.
Common Tansy flowers from July through September and can be found along roadsides and edges of fields. The stems and leaves of this heavily scented plant contain a toxic sap known to be hazardous to humans and animals.
Chicory - Cichorium intybus
Chicory is a member of the Sunflower family (Asteraceae) and is easily recognizable by its large blue flowers, each with multiple square-tipped petals. Each flower, borne against the plant's thick stem, lasts for only one day. The leaves of this species have a dandelion-like appearance. The roots can be roasted and ground up and have been used as an additive in or substitute for coffee.
