Campanula trachelium

 
Campanula trachelium
bats-in-the-belfry, nettle-leaved bellflower
Campanula trachelium
Nettle-leaved indeed

Common name bats-in-the-belfry, nettle-leaved bellflower
Family campanulaceae
Life cycle perennial (Z4-9)
Flowers violet-blue
Size 18"
Light full sun-part shade
Cultural notes well-drained soil, not too dry

Typical bellflower, with blue flowers on an upright but fairly small plant, with dark green leaves. Close-up inspection shows that the flowers and stems are slightly hairy. The flowering plants from last year didn't return this year (although last year's seedlings did, and are blooming now) – so it seems to have a biennial habit at least in our climate.

A white-flowered variety came up among a batch of the blue seedlings

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed for this plant is included on my seed trade list
