Possible Japanese stiltgrass, prohibited in NH if confirmed
Bring this list on the next visit. Each check takes a minute: crush a leaf, look where the leaves join the stem, or pull one stem. Tell Claude what you find and the plant moves up to CONFIRMED.
| confirmed | The features that set it apart are plain in the photo, and nothing that looks like it fits. |
| likely | Fits everything the photo shows, but a look-alike is still possible. One quick check on the next visit settles it. |
| unsure | Two candidates fit. The check names both and what tells them apart. |
| check | Could be a plant New Hampshire prohibits. Look in person before anything else, and move none of it. |
Photos in
The originals are kept on Ben's Mac. The copies here have the location data stripped out.
Look close
Each photo is checked full size, with close crops of leaf edges, stems, joints and seed heads.
Check the records
Matched against the 2026 plantings list, the collected seed shelf and earlier photos of these plants.
Check the state list
Anything that could be on New Hampshire's prohibited list (Agr 3800) is marked CHECK.
Write the test
Every ID short of CONFIRMED carries the one check that settles it, collected under CHECKS.
Whole plant, then a close leaf front and back, the spot where leaves join the stem, any flower or seed head, and the tag if there is one. Phone photos straight from the camera roll are fine.
