General Culture: Click for monthly care information.
Easily grown in average, medium, well-drained soil in full sun to part shade. Does best in full sun. Prefers a moist, fertile, acidic, somewhat heavy soil where plants can remain undisturbed for years. Needs additional moisture during spring growth and bloom (medium to wet), but will tolerate drier conditions thereafter. Plant bulbs in fall.
Noteworthy Characteristics:
One bulb produces a terminal spike of star-shaped flowers (20-80 flowers per spike) which rise to a height of 3-4' from a 2' tall clump of narrow (1" wide), linear, strap-shaped leaves (up to 2' long) which are somewhat grassy in appearance. Flowers of this cultivar are dark blue with attractive yellow stamens. Species is a native of western North American that grows in moist meadows. Good fresh cut flower.
Problems: Click for detailed list of pests and problems.
No serious insect or disease problems. Plants are strong and seldom need support.
Uses:
Mass or plant in groups of at least 12 bulbs in the perennial border or naturalized garden. May not deserve a prominent place in the border, however, since foliage can become rather scruffy in appearance after bloom. May also be utilized as a perimeter plant for a water garden or pond.
