The Rock Wall Garden was built in 1924, about the same time the area was changed into a Rose Garden, as an addition to the garden terrace begun in 1888. The Rock Wall is a six-foot high wall of Wissahickon schist filled with many alpine plants. It is situated on a sunny south-facing wall, well-drained and moist, with cool cracks, similar to alpine conditions. Plants with short stems, dense, tough or hairy foliage and those with long fibrous roots or taproots can live in this environment.
Due to weather concerns, all activities for Cherry Blossom Festival on April 9 are canceled. We will keep our fingers crossed for a great event next Saturday, April 16.
