Phyteuma is strictly a European genus with quite a few species, not very often seen in the gardens. P. scheuchzeri is the most common cultivated. It doesn’t look like a bellflower, that’s for sure – it looks much cooler!
The flowers are grouped in spiked, ball-like violet inflorescences (aka. floral-sea creatures) which at full bloom ‘explode’ becoming fluffy. Excellent in the rockery, edge of the flower border; contrasts beautifully with yellow flowered species, like Helianthemum, Anthyllis vulneraria, white – like Dianthus petraeus, pink…you get my idea :))
Germination: seeds are very fine, like of Campanulas; sown superficial in the fall or early spring.
