    Prince's plume

    yellow Prince's plume flowersDescription: Extremely drought-tolerant perennial to 5 feet tall
    with a large mound of coarse foliage at the base and tall plumes of
    lemon yellow flowers in summer.

    This species occurs naturally throughout the interior West and plains states. Though small, the flowers are numerous and open progressively towards the tip of the stalk; the effect in the landscape is quite spectacular.
