The raingarden planted at Princeton Borough's Senior Center along Harrison Street, just up from Hamilton St, is flourishing. The many wildflowers are just about to cut loose with colorful blooms.
It was dug by hand, with help from an old rototiller, and planted with native wildflowers and shrubs.
The garden captures runoff directed to it from the downspouts of nearby buildings. Rainwater accumulates to five inches or so in the garden, then seeps into the soil, feeding the plantings.
Click on the sign to enlarge it. Borough resident Curtis Helm provided the idea and the initiative, with some assistance at various points from me. Pinelands Nursery contributed the plants. The borough provided mulch to suppress weeds around the edges.
Here is a cardinal flower (Lobelia cardinalis), with bright red blooms about to open.
