This month’s mystery plant
is a herbaceous plant whose Flower Type is described in Newcomb’s Wildflower Guide as “Parts Indistinguishable”.

The plant grows from 6” to 24” high. 
It has alternate, toothed leaves
which are 2” to 4” long. 
The separate male and female flowers are found in the leaf axils and are subtended by 5-9 lobed, leaf-like bracts . 
The common name of this plant is a reference to the number of seeds
produced by each flower. 
This plant grows in fields, along roadsides and can also be found in moist areas. 
I have seen it growing vigorously
in stone walls. 
It begins to bloom in June and
sets fruit from July to September.

Stop back next month to find out
