General Culture:
Easily grown in average, dry to medium, well-drained soils in full sun. Somewhat tolerant of poor soils. Prefers dry, sandy or rocky, alkaline soils. Will grow taller in fertile loams, but may need staking. Intolerant of wet soils in winter. Tolerant of summer heat and humidity. This cultivar may not come true from seed.
Noteworthy Characteristics:
‘Monarch’ is a blazing star cultivar that is noted for its unusual ability to attract monarch butterflies. It is an upright, clump-forming perennial that typically grows to 2’ (infrequently to 3’) tall. Fluffy, thistle-like, deep rose-purple flower heads (each to 1.25”) appear on terminal columnar inflorescences atop erect, leafy flower stems. Stems rise up from basal tufts of narrow, lanceolate-oblong to oblanceolate, green leaves (to 6” long). Blooms in late summer to early fall. Liatris belongs to the aster family, with each flower head having only fluffy disk flowers (resembling “blazing stars”) and no ray flowers. Although the flowers of all species of liatris are sought out by butterflies, it is reported that the flowers of ‘Monarch’ are particularly attractive to Monarchs. Within an inflorescence, flower heads bloom somewhat at the same time, which makes this cultivar a good fresh cut flower for floral arrangements.
Problems:
No serious insect or disease problems. Watch for thrips.
Uses:
Good small native liatris for rock gardens. Mass in native plant gardens, cottage gardens and prairie areas. Also may be used in perennial borders. Adds vertical accent and late summer to fall bloom.
