Slender lavender-blue ray-florets surround a golden yellow disc, forming good-sized flowerheads to 8cm across, which top sturdy, well-branching stems from midsummer to mid-autumn. This award-winning Michaelmas daisy is highly prized for its vigorous growth and resistance to disease.


  • Garden care:
    To plant Aster × frikartii 'Mönch', choose a sunny spot with well-drained, fertile soil, ideally with a pH of 6.0 to 7.0. Space these perennials 40-50cm apart. Dig holes twice the width of the root ball, ensuring the crown is level with the soil surface. Water thoroughly after planting and apply a 5-10cm layer of mulch to retain moisture. Keep the soil consistently moist, fertilise in early spring, and deadhead spent flowers for extended blooms. Aster 'Mönch' is generally pest-resistant but monitor for aphids or powdery mildew, encourage natural predators to help deal with any aphids and selecting a planting location with good air circulation will help to offset powdery mildew issues.
