In the garden

Trollius europaeus 'Superbus' is a perennial from the Ranunculaceae family, native to Europe and Western Asia, cultivated for its compact habit and globe-like flowering display from May to July. Typical plants reach around 0.6 m in height, making them a mid-height element in the border. Choose a site in full sun or partial shade with loamy or clay soil that stays consistently moist to wet; the cultivar will tolerate soils described as moist but well-drained as long as they do not dry out. It is rated H7 for the UK, meaning it is fully hardy through normal British winters (USDA zones 3–7 give a comparable reference for colder regions). For heavier clay, incorporate organic matter to improve structure while preserving moisture-retentive qualities. Situate Trollius europaeus 'Superbus' where damp conditions are reliable: pond edges, the front of moisture-loving borders or alongside perennial swathes that prefer cool, wet soil. At about 0.6 m tall, its defined flowering window from May to July provides a clear mid-season presence that can be planned around later- and earlier-flowering plants.
