Harrison Street Raingarden in July

Another sight to be seen from Hamilton Avenue is the raingarden at Spruce Circle, just up from the intersection of Hamilton and Harrison Street. Type "raingarden" into the search box at the upper left of this blog and you'll find posts showing the raingarden in various seasons.

In July, the switchgrass (foreground) is fully grown, and the JoePyeWeed is in full flower (tall and purple).
A view uphill from the raingarden shows the long roof that feeds the garden during rains.
Here's a view from uphill looking down. Rain flows through the downspouts and out onto the grass, then down to the raingarden, where it collects and infiltrates into the ground over the next 24 hours or so, creating a nice underground reservoir of moisture to feed the roots of the wildflowers through droughts. Only in the most extreme droughts, such as the two-month long drought last year, does watering prove necessary.

Scattered through town, taking advantage of wet, sunny spots, raingardens like this one serve as lifelines for pollinators otherwise starved by the trees n' turf landscaping dictated by convention.
