Ionactis linariifolius

Native Plants

Stiff Aster

5 Photos


With its conifer-like texture, clump forming habit and drought tolerance, Ionactis linariifolius is an unusual addition to the rock garden or xeric site. Plants produce numerous, erect wiry stems with densely arranged stiff, needle-like foliage. Stems terminate in clusters of 1” wide flowers, ranging in shades of lavender, blue-violet, or white with a central yellow disc that matures to a bronze-red. Stiff aster grows 12-20” tall and prefers full sun in a sandy to gravelly soil but will tolerate some shade and a moist, well drained soil. This long blooming perennial complements Salvia lyrata ‘Burgundy Bliss’, Liatris pilosa, Silene virginica and Helianthus porteri.
