June’s mystery plant is described by Go Botany as “extremely rare in New England”.  First found by the author in Johnston and later in Providence in 2015, this plant is a small herbaceous perennial with 5-petaled yellow flowers and numerous stamens. The leaves are alternate, lobed and pinnate.  As the plants mature, a small stipe forms and pushes the achenes forward and separates then from the calyx. This plant begins to bloom in March to late spring and grows from 15” to 25” tall. It can be found in open woods and sometimes in open grassy habitats.
