The plant, at first glance, appears to be an Agave or Yucca. The flowers really give away the fact that it belongs with the carrots (apiaceae). The stems of the plant smell like carrot when crushed. Plant common names are, many times, an indication of a plant use in past generations. Native Americans and pioneers used the root of Rattlesnake Master extensively as an antidote to rattlesnake venom.
Definitely an accent plant, although care must be taken not to make groupings too excessive. Clusters of three should be sufficient for most landscapes. This species is best kept in the rear of the border flower stalks can reach up to 5' in height.
