The unknown plant for July 2019 is a small annual, alternate- leaved plant with very attractive blue flowers surrounded by a solitary bract called a spathe.  The spathe surrounds all of the petals including the two blue petals.
The leaf blades are lanceolate with entire margins and are 2-6” long, ½- 1” wide. This plant can be found growing in moist or shady ground and is not native to RI. The plant is in bloom from late June to early October.
