  3. Leaves - alternate, opposite, dark green, lance-shaped. Leaves lack petioles.

  4. Flowers -  clusters of scented, salver-shaped, pale pink flowers open in summer. The centre of the flower shows a narrow circle of slightly darker pink. Flowers are borne in terminal panicles, on narrow stems that grow from the stem tip, and from the leaf apices nearer the top of the plant.

Cultural details


Full sun to partial shade.


Moisture-retentive, fertile, otherwise not fussy.


Fully hardy.


Deadhead to prolong flowering season. In autumn cut the stems down to the base and mulch with compost or well rotted manure in early spring.


May be affected by slugs, snails, phlox eelworm and powdery mildew.



Divide in spring or autumn, take root cuttings in early autumn or winter or take basal cuttings in spring. New plants take a couple of years to bulk up and get going, but once they're well established they have a good long season with plenty of flowers.
