Stiff aster is an excellent, long-blooming, compact aster ideal for rock gardens or the front of the border and look great massed in groups. Ionactis linariifolius is easily grown in average, dry to medium, well-drained soil in full sun. The rather distinctive linear leaves are narrow and almost needle-like. Small flowers have blue-violet to purple rays and yellow center disks which appear at the ends of ascending stems in late summer to fall. Flowers are also an excellent late season nectar source for pollinators.
