Plant description
Great for pollinators and flowering for weeks in summer, this ornamental thistle adds strong vertical structure and contrast to borders. It produces tall, upright stems topped with white, pincushion-like flowerheads, ideal for prairie-style or naturalistic planting. The dark green, spiny foliage forms a tidy basal clump, while the soft undersides of the leaves give added texture.
Cirsium rivulare ‘Frosted Magic’ is compact and manageable, making it a useful perennial for mixed borders or wildlife-friendly designs. Regular deadheading encourages more blooms and prevents unwanted self-seeding. Leave seedheads over winter for birds or cut back in autumn for a neater look.

How to care for Cirsium rivulare Frosted Magic ('Lowcir') (PBR):
Cirsium thrives in moist, well-drained soil in full sun. Water well until established, especially in dry periods.
Cut back faded flower stems to encourage a second flush of blooms and prevent excessive self-seeding.
In autumn, trim plants to ground level to maintain a tidy appearance. Every few years, divide congested clumps between autumn and spring to rejuvenate growth and improve flowering.
