One of the fabled Blue Poppies whose sky blue flowers in late spring hold people in thrall. This was known for years as the species betonicifolia but was reclassified in 2009. This perennial species is one of the easiest to grow, A good fertile moist soil that drains in bright to dappled to part shade is perfect while avoiding hot sun and dry. Likes acidic soils, cool summers and coldish winters. Cannot be grown anywhere it gets hot and/or humid in the summer. Maybe the best choice among the blue poppies if you are a little warmer and drier than optimum for these divas.
