We are always looking for summer blooming perennials for shade, and here’s one you should consider. Many of us notice plants when their blossoms present themselves , and indeed Tricyrtis ‘Autumn Glow’ does captivate with its purple-blue orchid like flowers. I say that this form of Toad Lily deserves attention for its large and bold golden edged foliage. Ovate leaves grow to 6″ long and 3” wide and plants enjoy a rich, somewhat moist but well drained soil. Plants spread by stolons and clump up quite quickly, growing to 2’ tall and up to 3’ wide in dappled shade. ‘Autumn Glow’ is reliably winter hardy in zones 5-8.
The flowers, born in sprays from late July into early September, are lovely as cut flowers and do attract butterflies. Pair Tricyrtis ‘Autumn Glow’ with ferns, such as Athyrium otophorum, or golden leaved Hosta for a nice shady vignette.
