About

It performs well in full sun or partial shade on sheltered south-, east- or west-facing sites and prefers moist but well-drained soils of chalk, clay, loam or sand across acid to alkaline pH.

In the garden

A member of the Campanulaceae, Campanula rotundifolia 'Thumbell White' is a dwarf, mat-forming herbaceous perennial valued for low, spreading habit. Its deciduous foliage dies back in winter and the plant reappears from spring growth; flowering runs from June to September. Hardiness spans H5 to H7, which corresponds to hardy through to fully hardy in UK terms, so it suits most outdoor gardens without winter protection. Position it in full sun or partial shade on a sheltered site; south-, east- or west-facing aspects are all appropriate. The cultivar tolerates a wide range of soils — chalk, clay, loam or sand — but needs them to be moist yet well drained. It accepts acid, neutral or alkaline pH, so soil chemistry is rarely a limiting factor; avoid waterlogged locations and exposed, windy spots. Use 'Thumbell White' at the front of flower borders and beds, in cottage and informal schemes, or as a low ground cover in wildlife-friendly planting. Its dwarf, mat-forming habit lets it fill gaps between larger perennials and run along paths or edging where a low, spreading plant is required.
