Polemonium is hardy zones 3-9 depending on the cultivar.
Jacobs Ladder grows best in full to partial shade areas in well-drained, evenly moist soil. The soil should be rich in organic matter, with a soil pH of 6.1 to 7.8. Too much sun or heat should be avoided because the leaves are prone to scorching.
