Coville’s Phacelia, Phacelia covillei
While working at a job site this week, Jim and I discovered several locations where Coville’s Phacelia occurred.
Coville’s Phacelia is Maryland State Rare (S2), State Status Endangered.
The plant blooms in late April and into early May, has light blue violet flowers, with five petals, and with the leaves and stems having visible hairs.
The plant is an annual.
It is typically found in close proximity to streams, in clusters of floodplain forest and side slopes.
The MD DNR Natural Heritage Program and MD Biodiversity Project have five records of this plant occurring in Maryland, with all of the locations being in Prince George’s and Montgomery counties.
The plant has a very limited distribution, naturally occurring in Maryland, Virginia, North Carolina and Indiana.
Based on my observations, I’d say that peak bloom was this week, the third week of April, at our location.
This plant was observed as being locally abundant, with several aggregates totaling over 100-acres, and located in Prince George’s County.
