Clustered Bellflower (Campanula glomerata 'Superba')

Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Full sun is best in cool northern summer climates. Prefers part shade in hot summer climates. Needs regular moisture. Promptly remove spent flower stems to encourage additional bloom. Divide clumps in fall every 3-5 years to maintain vigor and/or control spread. Plants naturalize by rhizomes, and can be somewhat invasive, particularly in moist soils.
