Marcus Bridgewater on Instagram: "Earlier this summer, I spoke at @pollyhillarboretum and spent time exploring the grounds. Polly Hill was a horticulturalist, and this specific part of the arboretum (Polly’s Playpen) is a place where she personally planted and cared for some beloved plant varieties. If you visit Martha’s Vineyard, a visit to the arboretum is a must. I hope to see it in the fall someday."
