Some upper stems produce compound umbels at their tips made of tiny, yellow flowers; the umbels are very open (they remind me of a fireworks burst), up to 4-7" across with 12-15 umbellets of about a dozen flowers. Individual flowers are about 1/8" across with five tightly furled, yellow petals; five stamens emerging from between the incurled petals and widely spreading with pale yellow anthers; and two styles. Sepals are absent. The flowers tend to be either pistillate (stamens reduced or absent) or staminate (styles reduced or absent), but a few perfect flowers occur. Yellow pimpernel prefers dry habitats on a slope at the edge of woods.
