Daylilies (Hemerocallis) grow quite well here. Indeed, the species H. fulva, with its rich, rusty orange blooms, has naturalized as a roadside or farm margin wildflower.
I planted the bright yellow dwarf "Stella de Oro" in my little border, certain that it would thrive and provide color through the summer months. "Stella" was the first everblooming daylily, developed by amateur breeder Walter Jablonski in 1975. It is still widely sold and with good reason. It supplies color and reliability, and it was a good choice for a small space, such as this one!
