Plant information

Plant Description

Eupatorium ‘Eureka’ is a strong, upright perennial producing large, domed heads of soft mauve-pink flowers from late summer into autumn. The blooms are carried on sturdy stems above handsome green foliage, adding height, structure, and late-season colour to borders and naturalistic planting schemes. Highly attractive to bees, butterflies, and other pollinators, it is an excellent choice for wildlife-friendly gardens. Thriving in full sun or partial shade in moist, well-drained soil, this reliable variety works well in mixed borders, prairie-style plantings, and larger garden spaces

Salvias should not be cut back in autumn, as leaving the foliage intact helps protect the plant from frost.
