I live in Manhattan. I used to own a car and would go out to e.g. Scherer's, Hick's, Viette's, etc., to buy pond plants.
However I am now carless and going crazy trying to buy pond plants.

I've ordered a couple on the internet but they haven't been shipped yet and I would like some immediate gratification.

Does anybody know of any place that has pond plants that's accessible by subway (or even ferry, if there's a place on Staten Island)?

Chelsea Garden Center has a dormant water lily in a box, but it sounds too depressing to wait for it to grow

Thanks.
