Jacob ladders can be used in perennial beds as well as in natural gardens. High species such as the Blue Jacob's Ladder (Polemonium caeruleum) are well suited for shrub planting and look very beautiful next to meadow iris (Iris) and lady's mantle (Alchemilla). With its nostalgic charm, the Blaue Jakobsleiter also fits well in the cottage garden. In turn, low species are best kept in the rock garden. Jacob's ladders are an asset to the spring garden. The Rosa Jakobsleiter 'Lambrook Mauve' is also suitable as a cut flower. The low scented Jacob's Ladder (Polemonium caeruleum var. Villosum) fits perfectly in the bed foreground, can also be placed at the edge of the pond and also makes good in rural gardens.
If you make a complete pruning after flowering, you will get a second pile in September, but less bulky. Even those who want to prevent the spreading of Jacob's ladder in the garden should cut back the plant.
Scented Jacob's Ladder (Polemonium caeruleum var. Villosum) should be dug up and split every two to three years - this promotes vitality.
The plants can be divided, propagated by cuttings or sowing. The best time for this is spring.
