Campanula (Bellflower) Seeds - Diane's Flower Seeds
Campanula americana is a native wildflower with blue-green leaves and very tall stems of violet-blue flowers from July to October. The 1" wide flowers have five petals, and they are flat, rather than bell-shaped like most campanula species.

Campanula americana is a biennial that self sows prolifically to replace itself. It attracts hummingbirds and butterflies. Stratify the seeds. Hardy in zones 3-8.

height 3-5'  spacing 15"


Campanula rotundifolia is a beautiful wildflower with violet-blue, bell-shaped flowers from June to September. The short, spreading plants looks lovely in the border, rock garden or wildflower garden. I plant them around the base of roses.

Campanula rotundifolia is drought tolerant, and it self-sows in moderation. The seeds require 5 weeks cold-moist stratification. Hardy in zones 3-9.
