Ozark blue star
The lance-shaped, bright green foliage of Amsonia illustris is topped with panicles of light-blue flowers in late spring and early summer which contrast beautifully with the glossy leaves. This long-lived and reliable perennial shines with a glowing bright yellow in autumn before going dormant for the winter.
Colors & Combos
Great Color Contrasts: white, yellow
Great Color Partners: blue, green, pink, purple
Culture NotesThis long lived perennial prefers a rich well-drained soil and regular summer watering. Plant it in full sun for the best flowering and brightest fall color. Be patient with new young plants, often they can look a little straggly and forlorn and may take a few years to fill out. To help plants establish give them some space to minimize competition. Once they mature they will be long lived and robust, full specimens.
