Pokeweed - Phytolacca americana
This large-leaved plant has heavy, smooth reddish stems, and grows in damp thickets, clearings and disturbed areas. It produces long clusters of small white flowers in summer, followed by dark purple berries highlighted by flower stalks that turn a brilliant pink. The fruit and fleshy root of Pokeweed are poisonous to humans, but birds eat the berries of this native species. The juice of the berries can be used as a dye and in the past was used to "improve" cheap wine.
Butter and Eggs - Linaria vulgaris
This European relative of the snapdragon has a distinct yellow flower with an orange center. Each flower is about one inch long and has five lobed petals; two petals in the upper "lip" and three in the lower "lip." The flowers grow on long clusters on a stem covered with thin, linear leaves. Butter and Eggs can flower any time from May to October. It is commonly found along roadsides and in other disturbed areas.
