Description:

THE NEW STAR

Agastache 'Black Adder' is a recent addition and has become a star bedding plant for the end of summer.

  • It flowers abundantly with long deep violet blue spikes from July until the end of September.
  • A lofty upright habit reaching to about 1 metre high gives the plant a very light and vertical appearance.
  • This aromatic, bee-friendly plant is a joy for all nectar foragers.

All this makes Agastache 'Black Adder' an easy plant to use in different plant compositions.

The vertical structure of this agastache makes it a focus plant to contrast with bushy shapes in the garden.

Its intense flowers go particularly well with the orange umbels of Achillea 'Terracotta', the daisy flowers of the Echinacea, the bluish clouds of Calamintha nepeta 'Blue Cloud' or the blue balls of Echinops ritro 'Veitchs Blue'.

You can leave the dried plants where there are during the winter for decorative purposes. Prune and divide when spring arrives.

And with grasses? Effective association with Panicum virgatum 'Prairie Sky' , Andropogon scoparius 'Prairie Blue', Festuca glauca 'Elijah Blue'
