About plant names...

Tall Meadow Rue is native to North America.

Identification: Tall meadow rue is so named because the plants are somewhat larger than other rues, 3-8' (91-243 cm). Plants have rounded leaves, somewhat longer than they are wide, split into three shallow lobes at the ends. Flowers are cream-colored, occurring in large groups. Each flower does not have petals, just sprays of stamens about ¼" (8.4 mm) across. They bring to mind little pompoms or tiny white fireworks displays.
