Description / Amsonia 'String Theory' Bluestar

Amsonia 'String Theory' Bluestar, a Proven Winners® variety, is a perennial that enchants with its feathery foliage and fabulous flowers. The medium green threadleaf leaves retain their beauty and health throughout the summer, maintaining a soft textural element in the garden. Late spring sees clusters of light periwinkle blue flowers adorning this delightful plant, while fall brings a stunning transformation with a brilliant golden-orange hue. Both flowers and foliage are sought-after additions to floral arrangements.

'String Theory,' is a compact Amsonia hubrichtii species, commonly known as bluestar, blue star, blue star amsonia, threadleaf blue star, or Arkansas amsonia. It grows slowly and maintains an upright, clumping form. It excels as a specimen in the garden and serves as a captivating thriller in mixed containers. However, its true beauty truly shines when grouped or massed in beds and borders.

Bluestars are easy to grow. They thrive in sunny to partly shady locations with average to fertile well-drained soil. While it tolerates poor soils, it showcases its adaptability. Heat and humidity pose no challenge, and a touch of afternoon shade in hot summer regions can be beneficial. The best fall color spectacle unfolds in full sun. Once established, 'String Theory' exhibits moderate drought tolerance and stands firm as a deer-resistant beauty.

As a native North American plant, bluestars not only capture attention with their beauty but also contribute to environmental harmony. Adapted to the climate and soil conditions of the region, they thrive without the need for fertilizers or extra watering, once established. Native plants also act as natural pest controls, reducing the need for pesticides in the garden. Landscaping with native plants promotes biodiversity and provides shelter and quality food for the wildlife and pollinators that bring gardens to life and enhance their appeal.
