General Culture: Click for monthly care information.
Easily grown in average, dry to medium moisture, well-drained soil in full sun to part shade. Best in full sun, but tolerates some light afternoon shade in hot summer climates. Tolerates a wide range of soils, but may perform best in rich, sandy loams. Established plantings have some drought tolerance. Plant bulbs in fall. Plants form dense, slowly-spreading clumps which may be divided in either spring or autumn. Deadhead flowers before seed sets to help control any unwanted spread.
Noteworthy Characteristics:
This ornamental onion is a rhizomatous, bulbous perennial that typically forms a basal clump of linear, grass-like, somewhat twisted, narrow green leaves to 6” tall. Pink florets appear in globular clusters (umbels) atop leafless stalks rising above the foliage to 12-16” tall in summer (July-September). Flowers are mildly fragrant. All parts of the plant have an oniony aroma when cut or bruised.
Problems: Click for detailed list of pests and problems.
No serious insect or disease problems. Bulb rot may occur in overly moist soils. Plants may colonize over time, but are not considered to be as aggressive as some of the other alliums.
Uses:
Rock gardens, border fronts, herb gardens. Good edging plant for gardens or paths.
