Milky Bellflower is a compact, bushy perennial that brings soft elegance to garden borders and naturalized plantings. Native to the Caucasus, Campanula lactiflora 'Pouffe' grows 12-18 inches tall with pale blue to milky white bell-shaped flowers that bloom prolifically from June through July. Hardy in zones 5-7, this low-maintenance perennial thrives in full sun to partial shade and produces flowers excellent for cutting, adding a delicate touch to arrangements. Its semi-evergreen foliage in milder climates and deciduous growth in colder regions make it adaptable across its hardiness range.

The pale blue to milky white upward-pointing bells appear in abundance over a relatively compact mound, creating a generous bloom display from a plant that stays under two feet tall. Flowering for 4-5 weeks during summer, it requires minimal fussing once established and resists browsing deer entirely. The flowers are substantial enough for cutting while the plant itself needs almost no deadheading or staking, making this an unusually low-labor choice for gardeners seeking summer color.
Milky Bellflower is grown primarily for ornamental purposes, particularly for naturalizing in borders where its modest height and long bloom season provide sustained color. The flowers are valued for cutting, holding well in arrangements and bringing an airy quality to fresh bouquets. Its deer resistance makes it especially useful in landscapes where browsing wildlife would eliminate many other flowering perennials.

Milky Bellflower requires minimal pruning. Deadheading spent flowers will encourage continued blooming through the season, though the plant performs adequately without intervention. In early spring as new growth emerges, remove any dead foliage from winter dieback, particularly in colder zones.

“Campanula lactiflora originates in the mountain regions of the Caucasus, where it evolved as a hardy perennial adapted to cool, moist conditions. The 'Pouffe' cultivar represents a deliberate selection for compact growth, making this species accessible to gardeners with limited space. The variety name reflects its tidy, cushion-like form, distinguishing it from taller selections of C. lactiflora that can exceed three feet.”
