Amsonia tabernaemontana, commonly called Eastern Bluestar, is a refined clump forming perennial known for its pale blue star shaped flowers and graceful arching stems. In spring, it creates a soft bloomy display that transitions into lush green summer foliage. Height & Spread: 2.5 - 3 x 2 - 3 ft Bloom Time: Late spring (April to May) Light Requirements: Full sun to part shade Soil Preference: Moist, well drained soils; tolerates loam and clay Watering Needs: Moderate; more drought-tolerant once established Deer Resistance: Excellent; deer tend to avoid due to its latex like sap NATIVE STATUS Native to the southeastern and central United States, thriving in floodplains, open woodlands, and streambanks. It plays an important role in supporting regional ecosystems and is well suited for North American native and restoration gardens. WILDLIFE & INSECTS Butterflies Especially attractive to spring butterflies like swallowtails, which rely on its early bloom. Bees Native bees, including bumblebees and sweat bees, use its nectar during critical early season foraging. Other Insects Serves as a resting and sheltering site for various beneficial insects throughout the growing season. While not a larval host plant, its ecological value as a nectar source and seasonal cover is notable. SPACING & LANDSCAPE USE Spacing Recommendations Space 2 - 2.5 ft apart for best airflow and to maintain distinct clumps. Landscape Placement Perfect for mixed borders, native plant groupings, rain gardens, or as a softening edge near paths and patios. Its fine textured foliage pairs well with both upright and sprawling companion plants. COMPANION PLANTS Aquilegia canadensis (Wild Columbine) - for contrasting flower form and early bloom overlap. Penstemon digitalis (Foxglove Beardtongue) - adds vertical accents and attracts pollinators. Symphyotrichum oblongifolium (Aromatic Aster) - for extended color into fall. Baptisia australis (Blue False Indigo) - mirrors blue tones and adds structural interest. Pycnanthemum tenuifolium (Narrowleaf Mountain Mint) - for fragrance and pollinator value.
