plant-wise, there's a lot to see. in addition to that gorgeous tree (is it a redbud? crab apple? update: garden compass told me it was an eastern redbud), there is also birch and what i think is a maple tree. there's also a "fragrance walk" with azaleas, mint, sweetbay magnolia, and ruby spice summersweet. schoolchildren from p.s. 372 next door tend to the edible garden, which included parsley, mint, rosemary, and lettuces the last time i check. (hhh and i often wonder if we are allowed to pick them? have not yet done so.) design-wise, it's actually pretty hard core. there is a "high performance storm water infrastructure," which helps to keep the area around it from flooding. one of the plaques in the garden shows the history of gowanus and why flooding occurs, and explains how the fancy-schmancy technology underneath the park (i don't understand terms like "bioswale" and won't pretend to) diverts/absorbs 150,000 gallons of floodwater a year, preventing it from overwhelming the city sewers. (nice for me, since we live just across fourth avenue.)
