Amsonia tabernaemontana
Eastern bluestar (Amsonia tabernaemontana) is a perennial that reaches 90 cm × 90 cm after ten years. Light: full sun, part shade. Hardy down to -40 °C. Drought tolerance: medium. Mildly toxic to children. Sold in local shops from about €8.
A long-lived perennial that builds a dense, bushy clump: pale blue starry flowers in late spring, then narrow leaves that turn golden yellow in autumn. It grows with very little care in sun or part shade in ordinary garden soil and copes with short dry spells once established. It is slow to get going and needs two or three years to show what it can do, so leave it undisturbed.
