Daylily
Hemerocallis fulva
A tough, low-care perennial with bold orange flowers that each last a day, spreading fast into dense clumps that crowd out weeds and hold slopes. That vigour is the catch: it has naturalized along roadsides across North America, and Maryland and Delaware ban its sale. It's reported toxic to cats.

Spacing
VeraScape spaces plants so their grown canopies just touch. For Daylily, that’s about 2.5 ft apart, center to center.
Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
