From our guide

Village of the Hills

Herbaceous vine with intricate lavender flowers and edible fruit. Dies back in winter.

Why it works here

The larval host for Gulf fritillary butterflies — plant it and they will find it, usually within a season.

Watch out

Spreads by underground runners well away from where you planted it. Site it where that is acceptable.
