  • Campanula rotundifolia var. velutina A. DC.
  • Campanula heterodoxa Vest ex Schult.



Perennial, typically glabrous, rhizomatous herb growing from a taproot, up to 80 cm tall with bluish purple flowers.[2] Leaves entire;[3] basal leaves long petiolate,[3] round to broadly ovate;[4] cauline leaves alternate, linear, to 8 cm long.[2] Inflorescences racemose.[4] Flowers radially symmetrical,[3] calyx lobes 5, linear;[2] corolla campanulate, bluish purple, 5-lobed;[3] stamens 5; ovary inferior, becoming nodding 3-celled capsule, 4-8 mm long.[2]

Bloom Period

June - September[2]


Widely distributed throughout Washington; circumboreal.[2]


Open, rocky areas across altitudes[2] with sandy, well-drained soils.[5]


First Nations - Use by a number of different tribes as heart and ear medicine, and as a fumigant for eye medicine. Navajo use as spiritual medicine for protection.[6]

Wildlife - Attracts Butterflies, moths, birds, and bees.[7]



For best results, seeds should be sown inside and not covered after sowing. They should be bottom-watered. These seedlings will germinate quickly but will not flower until the second year. Root cuttings or stem cuttings stuck in damp sand are other propagation methods useful for this species.[8]

FloweringTime June- Sept
Seed CollectionTime Late July through mid-Sept.
Crop Intervals Perennial

Fruit/Seed Dormancy and Treatment:No treatment. Seeds may need light for good germination.


Seed sample from: 2011

Average Measurement: 1 x 0.4 x 0.2

Measurement Range: L: 1 - 1.1, W: 0.3 - 0.5, D: 0.2 - 0.3

Shape: Seeds tapering slightly at hilium end and opposite apex.

Color: Hilium and opposite end are dark brown. The rest of the seed is light brown.

Surface:Seeds longitudinally striate and glossy.

Latitudinal Cross Section: elliptical CARO lat.png

Longitudinal Cross Section: elliptical CARO long.png

Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
