Anagallis monelli, commonly called blue pimpernel, is a low-growing tender perennial of the primrose family that grows to 6-10” (less frequently to 18”) tall and spreads to 20” wide. Saucer-shaped, deep gentian blue flowers (to 3/4” diameter) bloom non-stop from early summer to frost on sprawling stems clad with lance-shaped to elliptic, medium green leaves (to 1” long). Each flower has five overlapping petals and a small red center. It is stunning combined with contrasty blooms and foliage like Ursinia anthemoides and Heuchera ‘Marmalade’.
Winter hardy to USDA Zones 8-10 where plants are best grown in light, sandy/humusy, consistently moist, well-drained soils in full sun to light shade. Plants will flower poorly in too much shade. Thrives with little or no water after established and self-sows!
No serious insect or disease problems. Aphids may be troublesome. Root rot may occur in poorly drained soils.
