I planted two of these last year. They survived a brutal, and I do mean brutal, Minnesota winter. They are a lovely mounded shape and are absolutely covered with beautiful light blue flowers. I find the foliage of polemoniums very pleasing, and it always looks clean and nice even when the plant is not blooming. This is definitely a keeper.

Positive plant_it On Jun 17, 2013, plant_it from Valparaiso, IN wrote:

The preference is light shade or partial sun, mesic conditions, and a rich soil with lots of organic matter. It is not aggressive.

The common name of Polemonium reptans refers to the pairs of opposite leaflets on the compound leaves, which supposedly resemble a series of steps on a ladder in a dream by the biblical Jacob.

Don't confuse this plant with the other species that resembles it, Polemonium vanbruntiae (Greek Valerian), which is native to some of the Eastern States. This latter species is more erect in habit, and has slightly larger flowers with exerted stamens. These flowers are usually a darker shade of blue than those of Jacob's Ladder, and their anthers are often yellow, rather than white.

This plant is having a difficult time growing in our yard. We have heavy clay, which stays pretty dry and hard. Also, I have it planted in shade with no direct sun after the trees leaf out. I planted it in spring of 2005 and it barely comes up each spring and then dies back during the summer. Never any flowers.

This plant make a nice company for woodland phlox, and one year they bloomed together! This species may be more long lived compare to other polemonium speces like P. caerul... It grows in sandy soil in any degree of shade at my home.

This is a nice plant for the shade garden. It seeds about nicely but not aggressively, and seedlings are easy to dig and transplant.

It makes a nice dainty cutflower with pink columbine and other delicate spring flowers.
