Polemonium acutiflorum
Polemonium acutiflorum, a northern Jacob's ladder relative, thrives in part shade with consistently moist, well-drained soil rich in organic matter. It is well suited for woodland garden borders and cool-climate landscapes where it produces attractive blue-violet flowers in summer. Mulch around the base to retain moisture and keep roots cool.
