Wildflowers – Barton Arboretum and Nature Preserve

Wildflowers

In the late 1990s and early 2000s, residents Rudy Salati and members of the Medford Leas Wildflowers Group developed a database of wildflowers found on the Medford campus of the Barton Arboretum. Now, in the 2020s, a group of residents is expanding that list to include the Lumberton campus and the meadows on both campuses that have been reborn in the last two decades.

Additional information about and photos of wildflowers in the Barton Arboretum may be found in Fred Kahan’s Around the Leas posts, the series on Lumberton Meadow Wildflowers by Miriam Swartz and Robert Koch, on the Meadows page, and in this video of photos from an early morning walk in the Medford campus meadow made by Dave Bartram in September 2022.
