Looks like lilies to me. My plant ID app says they're tiger lilies according to its magic. No idea how it can tell.
This is so cool! Im thinking on making a large lifted bed of lilies myself. Was thinking on tree lilies (the very tall ones). I still need to do something about the wind on our front lawn, so fencing would come first.
Nice! My zinnias are all starting up too as well as my super slow growing Dahlias. Really getting towards full flower season.
