Phalocallis coelestis
Phalocallis coelestis is a South American bulb related to the iris, featuring pleated blue-green foliage and blue, goblet-shaped flowers on 2-foot tall stems. The flowers, which have six petals in a mix of blue-lavender and tricolor, last for one day but bloom in succession over several months. This drought-tolerant plant prefers a well-drained sunny spot.
