Bluebell Family (Campanulaceæ)
(A) Bellflower (Campanula rapunculoides) (European). This beautiful European species is a frequent escape from gardens and is quite firmly established in several localities in the Eastern States.
The simple stems are erect and quite tall, ranging from 1 to 3 feet high. The toothed, lance-shaped leaves alternate along the lower portion of the stem and the bell-shaped purplish flowers are in loose spikes on the terminal portions.
(B) Harebell; Bluebell (Campanula rotundifolia) is the “Blue Bells of Scotland” so familiar to us in song and verse. It is a very slender-stemmed species but very hardy, as attested by the altitudes at which it is found on mountains. The flowering stems are very slender and wiry, sparsely set with linear leaves; they usually branch near the summit, each division bearing a demure, drooping violet bell. It is found in bloom from June until September in rocky or sandy places in Canada and northern United States.
