Polemoniaceae: Attractive, blue flowers are produced from June to September on tall stems. Height to 1 metre. Moist, well-drained soil in sun to semi-shade. Seeds have been collected from our plants which were grown from seed collected by Chris Chadwell on his expedition to the Himalayas in 2013.
The herb has astringent and diaphoretic properties. It was formerly used internally in the treatment of a wide range of conditions ranging from headaches to fevers and epilepsy.
Very easily grown plant, preferring a moist well-drained fertile soil in sun or semi-shade, but dislikes damp or heavy soils. Cats are strongly attracted by the smell of this plant and will frequently roll around on it.
Sow seeds in autumn or spring in a cold frame autumn or cool greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
