About
Leucanthemum x superbum 'Wirral Supreme' is a cultivated Leucanthemum in the Asteraceae family prized for an extended summer display. It flowers from June to September, offering a long season of blooms. Suited to positions where repeat flowering is wanted, it performs well in mixed herbaceous borders and for summer cutting. Plants establish into clumps typical of the genus and reward routine deadheading with continued bloom.

In the garden
A named cultivar within the genus Leucanthemum and a member of the Asteraceae family, Leucanthemum x superbum 'Wirral Supreme' is grown principally for its reliable summer flowering. Its bloom period runs from June to September, providing a sustained sequence of flowers through the prime months of the UK growing season. The cultivar status indicates selection for garden performance within the wider group of Leucanthemum plants. Plant where its summer display will be visible, such as mixed herbaceous borders, cottage-style schemes or beds kept for cutting. Keep plants in well-drained soil and allow room for each clump to develop; routine removal of spent flowers extends the flowering run. Where winter protection or lifting is practiced for other border plants, treat these plants in line with the surrounding herbaceous perennials rather than as an annual. Maintenance is straightforward: tidy the clumps in autumn and remove dead foliage, and lift and divide congested clumps if flowering declines. The long June–September flowering window makes Leucanthemum x superbum 'Wirral Supreme' particularly useful where a steady supply of summer blooms is required for garden display or cutting.
