Cirsium rivulare 'Frosted Magic'

Cirsium rivulare ‘Frosted Explosion’ is a new variety of ornamental thistle, introduced in 2016. Its pure white flowers appear on tall stems for several months in summer. It looks good in a cottage garden alongside other tall perennials, or in naturalistic planting schemes, mixed with ornamental grasses.

Grow Cirsium rivulare 'Frosted Explosion' in moist but well-drained soil (‘rivulare’ means ‘growing by a river’), in full sun. Cut plants back in autumn to prevent them self-seeding, or leave them intact to provide a winter source of food for birds. Lift and divide congested clumps in autumn or spring.
