Male and female flowers are on separate plants. Flowers of both
sexes are petal-less and about ¼ inch across, with 4 or 5
light green sepals that drop off early on the female flowers. The female flowers have
what looks like about 10 thick thread-like white to greenish petals. These are pistils,
rather than petals.
Male flowers have numerous dangling yellowish green to purplish brown stamens with pale
yellow tips that turn brown with maturity. For both sexes, flowers are
in large open clusters on the upper branches of the plant.
Leaves are twice compound in groups of 3 or 5. Leaflets are ½ to ¾ inch long and about as wide, hairless with a slender stem. Each leaflet is notched or lobed at the tip end in 3 or more rounded parts. Attachment at the main stem is alternate, while the leaflets are oppositely attached.
Clusters of seed capusules form on the female plants. Each capsule is about ¼ inch long, green and generally oval
with distinct vertical ridges and a brown stub of a pistil at the top.

Have you seen this plant in Minnesota, or have any other comments about it?
I've found this growing in both Kaposia Park and Simon's Ravine Park in South St Paul, but you have to get off the main trail in order to see it. I also found young plants growing in Sunfish Lake Park Reserve in Washington County, as well as deep within Maplewood Nature Center's complex of trails. I've seen a very few plants in the woods across the road from our home in South St Paul, but didn't see any there this year. I did collect some seed from a plant in Simon's Ravine a few years ago, and it did start successfully from seed in my shady garden. While the flowers aren't showy, I just love the airy foliage!

Early Meadow Rue began growing in my front yard garden about two years ago. It's a volunteer from somewhere. But a delightful plant nonetheless.
