This is one of those plants that is so unobtrusive until it comes into bloom and then is so outstanding that you are always taken pleasantly by surprise. 'Lucerne' is so easy to grow, tolerating most any well-drained soil and full sun and sporting clean, deep green, narrow grass-like or iris-like foliage that forms a clean, upright landscape tuft that is pleasing but unremarkable. Loads of buds begin to form in early May, emerging from the foliage, and the plant transforming show is ready to begin. Buds open in mid-May with an explosion of deep blue, yellow centered, 3?4" six lobed flowers that are stunning against the deep green backdrop. These flowers continue to open well into July providing a great nectar source for native bees and small butterflies while its foliage provides cover for small mammals. Plant it in groups in the foreground of the garden a show that is as unexpected as it is long.
