Eastern Bluestar: A Perennial Star for Fall Gold and Spring Blooms

With knockout foliage and an open, loose form, eastern bluestar (Amsonia tabernaemontana) fits any garden style — and right now, it's putting on a show. Delicate, elongated leaves turn gold with frost, held erect on stiff stems as winter approaches. One of the very best perennials for mixed borders — texture, form, end-of-year star appeal — and deserves wider recognition.

Distinguishing Traits

Chartreuse leaves pair beautifully with fothergilla and ornamental grasses. Leaves are wider than those of willow bluestar (Amsonia hubrichtii), a related species with similar habit — also excellent for late-season color.

Early summer brings tiny pale blue star-shaped flowers — the source of the common name. Blooms fortify honeybees and feed other pollinators.

Design Uses

Replace lawn with swaths of low-maintenance plants like Amsonia and grasses. If keeping some lawn, at least reduce it. Textural interplay of a chosen plant palette appeals year-round. For naturalistic borders, combine bluestar with asters, baptisia, and bluestem (Schizachyrium scoparium); mass dwarf Amsonia 'Blue Ice' as ground cover. Bluestar forms clumps, excellent for pathway edging.

Planting Notes

Resistant to diseases and pests; holds up in hot, dry climates and poor soils. Divide established clumps after 5 years (early spring). Shear after flowering to maintain height (cut top third with hedge trimmers). Excellent compact cultivars: 'Montana', 'Blue Ice', 'Short Stack'.
