About this cultivar:

Polemonium yezoense var. hidakanum 'Polbress' is a herbaceous perennial with foliage that is purple-tinged in spring and autumn. It bears clusters of sky blue flowers, marked in a darker blue with a small white centre. These are cupped in shape and are held in clusters from late spring to midsummer.

It originated from a 1995 cross-pollination of the Polemonium cultivar 'Purple Rain' as the female, or seed, parent with a selection of Polemonium yezoense. The end result is very similar to 'Purple Rain' but taller, broader, and more erect in habit.

    About this genus:

    Polemonium (pol-e-mo-ne-um), commonly called Jacob's ladder, is a genus of between 25 and 40 species of flowering plants in the family of it's own name (Polemoniaceae), most of which are native to cool temperate to arctic regions of the Northern Hemisphere. 

    They are perennial plants (rarely annual plants) growing 10–120 cm tall with bright green leaves divided into lance-shaped leaflets, and produce blue (sometimes white or pink) flowers in the spring and summer. A few of them have a pleasant smell!

    The name Polemonium comes to us from the Greek "polemos" or "war"'. As one story goes, two princes both claimed to have discovered the plant and from that dispute, the genus name Polemonium was derived. Or it could be from the lance shaped leaves... or it could be that Dioscorides named it after King Polemon of Pontus. Take your pick.

    Polemonium plants prefer partial shade and wet-but-not-waterlogged conditions.  We've found full sun to be fine (on these islands).  If you cut back Polemonium plants in late spring, you may also get a second flush of flowers. Try pairing Polemonium with Astilbe, Heuchera, Carex, or other small spring bloomers.
