Physalis grisea — downy ground-cherry
Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
This annual plant is called downy ground-cherry for the abundant soft hairs that cover its leaves, stem, and inflated calyx, giving the whole plant a gray-ish cast (hence the species name, "grisea." The bent hairs are interspersed with glands. The fruit is rust-colored. The toothy leaves have net-like venation patterns.
Habitat
Anthropogenic (man-made or disturbed habitats), meadows and fields
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

3. Physalis grisea (Waterfall) M. Martinez E
downy ground-cherry. Physalis pruinosa, auct. non L.; P. pubescens L. var. grisea Waterfall • CT, MA, ME, RI, VT. Fields, waste areas. Physalis grisea has a confusing taxonomic history and, in part due to the missaplication of the name P. pruinosa L., has been confused with P. pubescens in various treatments (see Martinez 1993 for correct application of the name P. pruinosa).
Native to North America?
Yes and no (some introduced)
Sometimes confused with
- Physalis heterophylla:
- petals 10-20 mm long, sepals mostly 6-12 mm long during flowering, and plants perennial from rhizomes (vs. P. grisea, with petals 4-10 mm long, sepals mostly 3-7 mm long during flowering, and plants annual from a taproot).
- Physalis pubescens:
- plant with non-viscid pubescence and no glands, leaf blades green, berries green, and anthers blue to purple (vs. P. grisea, the plants with viscid pubescence and sessile glands, leaf blades gray-green, berries orange to orange-brown, and anthers usually yellow).
Synonyms
- Physalis pruinosa, auct. non L.
