Plant details

Jacob's ladder, Polemonium caeruleum, is a lovely clump-forming perennial, requiring little maintenance. It performs best in borders with moist but well-drained soil. In early summer it produces bell-shaped flowers, which can be prolonged by regular deadheading. In addition to making an excellent border plant, Jacob's ladder is rabbit proof! Plants can be propagated by sowing seed in autumn or spring, or by dividing plants in spring. Polemonium caeruleum 'White Pearl' bears white flowers in June.

As well as being rabbit proof are also slug and snail proof but the flowers are edible for humans so great in salads and cake decoration.
I have flowers on the different plants from March to November, and the bees and pollinating insects love them.

Very easy to grow from seed and you can pretty much leave it to its own devices all year, I get a lovely range of white and purple flowers from Mid May onwards.

It is not yet flowering but I'm looking forward to a splendid show.

I have one from a cutting I took a few weeks ago and to my surprise it took. It is now 12" high and in flower. will have to put it in the garden now and wait for other surprises.
