This summer the Architect of the Capitol is growing lovely plants like these in containers all over the Capitol campus. This one is right across the street from the Jefferson Building. Do you know what it is?

I’ll give you a few hints. 1) The stem is triangular in shape, not rounded like most plant stems. 2) These plants prefer marshy, wet ground and can be found along rivers and in shallow waterways. 3) It is not native to DC or North America. 4) The plant has historical importance to our work at the Library of Congress.

Here’s a closer view…
