Aster tongolensis Berggarten



Large lavender blue flowers with yellow centres

This ground hugging perennial gives a carpet of colour from summer through to autumn when the leaves are covered in sparkling lavender-blue daisies, each with golden centres.


Unlike its taller relatives this aster is best planted at the front of a border and also works well in a rock garden, easy to grow in a sun or part shade.


Happy in any moist, well-drained soil. Add some coarse grit to the planting hole if your soil is heavy and stays wet in winter. Water in well after planting.

This species of Aster has its origins in western China and the Himalayas.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.

Planting site Rock garden, Flower border and beds, Cottage garden, Informal garden, Gravel garden
