Showy 3-foot spires crowded with wide-flaring snowy flowers that overlap with the bloom time of late-spring favorites such as Baptisia australis and Amsonia tabernaemontana. The possibilities for this wonderful and little-known beardtongue should be obvious. Sun and well-drained soil are ideal. Zone 4. Propagated from seed. Deep 3.5-inch pots. Photo: Emily Geest
