Magnificent Calder Gardens
I'm also in love with the Calder Gardens and look forward to seeing that develop - all natives. I'll need to revisit (saw it last in September when it opened) to determine whether/where rain gardens are. Even though it was brand new and exists alongside busy major thoroughfares, it succeeds in slowing down time and space for me.
(And across the street there's the Rodin Museum Garden: formal gardens, very European with so much seating around grassy section.)


I love the rain garden outside of the Media Free Library, designed by Refugia. Its a fairly small space and has a great mix of water-loving trees like bald cypress, woodies and perennials. I love the way the path is laid out and the use of wood planks over the drainage area, and also that’s the whole area is not super wide so maintenance & access for weeding etc. doesn’t look too bad.
I also love the rain gardens outside the Haverford Environmental & Rec Center as well as the parking lot near the Media Courthouse. We need more parking lots like those!
Also a fan of Stoneleigh (love the mixed hedge too! And I am fascinated by the bog gardens near the bathrooms), and the Mt. Cuba Center (spring ephemerals! So magical).
