Campanula glomerata Superba seeds - Clustered bellflower

Campanula glomerata 'Superba', or Campanula 'Superba', is a very popular perennial plant in gardens with its beautiful clusters of intense bluish-purple flowers. An excellent plant for borders in cottage gardens, it performs very well in flower beds. It is a robust and hardy plant that can withstand temperatures as low as -15°C. Also, pick it for fresh bouquets.

Campanula glomerata, from the Campanulaceae family, originates from temperate zones in Europe and Asia. This cultivar, 'Superba', stands out for its compact and upright habit, forming a dense tuft. Its stems bear green, lanceolate and slightly hairy leaves. The 10 to 12 cm long basal leaves, are often heart-shaped, while the leaves on the stems are smaller and narrower.
The straight stems are about 50-60 cm tall and carry bell-shaped, deep purple flower clusters in summer, 2 to 3 cm in diameter. Flowering mainly occurs from June to July, but it can extend into September-October if faded flowers are removed after the first wave of blooms. This cultivar has moderate growth and spreads easily via rhizomes, creating a dense carpet over the years. The flowers of Campanula glomerata 'Superba' attract pollinators like butterflies and bees. This flowering is followed by the formation of fruits, called capsules, containing numerous small seeds that readily self-sow in the garden.

Campanula glomerata 'Superba' is perfect for perennial beds, borders, or cottage gardens. It pairs wonderfully with plants with yellow or white blooms for a strong contrast. Pair it, for example, with Delphinium 'Magic Fountain Mix', purple foxglove, Perennial Geranium 'Patricia', or even 'Coronation Gold' Yarrow. Together, these plants create an appealing colour palette. For amateur flower arrangers, this campanula is an excellent choice.
