Question
Hi. I am trying to identify a few native grasses at the Medfield Charles River State Reservation. Can you confirm the grass with purple seeds is Purple Top (Tridens Flavus)? I am also trying to identify the tan wheat-like grass growing with it. Are you able to identify what that grass is? Thank you!
Answer
Dear dteany, good morning. Identifying grasses from images is very difficult, and I need images of leaves, ligules, close up of flowers, etc. From what I can see, the plant with purple coloration may be Poa pratensis (blue grass). You can confirm it belongs to this genus by carefully teasing one of the spikelets apart and looking for cobwebby hairs attached to the base of the florets (these can be seen with 10x magnification.) The light brown grass I cannot see details well enough. If you get additional images (and closer images) I can likely get you the genus. Best wishes.
