Spikes of yellow flowers brighten the early summer garden. One of the most colorful tall flowers available, Eremurus (Foxtail Lilies) Bungei (Stenophyllus) grows 4-5' tall and blooms in May-June. Native to the drier regions of western and central Asia, foxtail lilies have a compact root, strap-shaped leaves and hundreds of small, individual flowers that attract pollinators. They're showy as a cut flower, too. Deer-resistant perennials, foxtail lilies bloom for 10-15 years without dividing. For the best garden performance, plant Eremurus in full sun.
