An old library book, Gardens of Philadelphia, made me aware of Highlands Mansion, and…read morecoincidentally friends wanted to have a play date at Kids Castle, so on our way home we checked out Highlands.
The mansion is apparently under restoration so I did not tour it, but I did see the gardens. While these gardens are nothing compared to the scale of the Brandywine DuPont estates, they are impressive for a former private residence. The most remarkable thing about them, to me, is their use of dramatic tall freestanding walls. Designers seem to agree that the best tool for success in landscaping is creating outdoor "rooms" or dedicated areas with hedged/fenced/walled/etc. boundaries to delineate and discern one outdoor space from another. I've toured many gardens domestic and abroad and I've never seen such a liberal use of wall structures that were apparently built solely for ornamental landscaping purposes (as opposed to ruins or retaining walls). Yes, you see decorative walls employed at Longwood and Chanticleer, but none so gigantic as these. Highlands was working with flat plain meadow and the goal seemed to be to create multiple garden-framed large lawn spaces, free of tree debris or too much shade to affect the grass. The walls are designed to tower as high as ornamental trees, but without the maintenance, root issues, leaf drop, etc. and they green-ify these walls with ivy trained all over them. Voila, vertical garden, architectural interest, height, and allowance for terrain diversification.
I grew up adjacent to the trove of magnificent DuPont estates in the Brandywine Valley. I'm now fortunate to live 2 1/2 mi from Chanticleer and 7 1/2mi from Tyler Arboretum (Jenkins is closer but it doesn't appeal to me). I would recommend the destinations closer to me for full day visits, while Highlands gardens would only take a half hour for the formal area, and more if you choose to hike a trail or tour the manse. Still, it may be a half-day visit at most.
While not a day trip destination on its own, it is a worthy stop if in the area, and I do recommend it to anyone interested in garden design who's already toured the others I mentioned. This is also an event venue, and the formal space is certainly made for such use, so it's lovely people can enjoy the space as it was intended when conceived.
