Plant used to feed butterflies...

[Hermopolis]

At the botanical gardens in Galveston, TX, they were using this plants to feed the butterflies in their butterfly garden. I tried asking the helpers there what it was but nobody I asked knew. Can anyone identify this plant? Thanks, Hermes.

Hearts and flowers is the common name I often hear for this one
