Mostly climbing or trailing plants, free, often luxuriant, sometimes rampant, in habit, with bluish, violet, purple, white, or yellow flowers, produced most profusely, and sometimes deliriously fragrant. They are most suited for covering stumps, planting on rocky places, among low shrubs in copses, for draping over the faces of rocks, sunny banks, or the brows of sunk fences, covering objectionable railings, rough bowers, chalk pits, hedges, etc., and occasionally for isolating in large tufts in open spaces where their effect could be seen from a distance.

Not particular as to soil, the stronger kinds will grow in any ground, but the large-flowered new hybrids will thrive best in warm, rich, deep soil.

C. Viorna, C. flammula, montana, campaniflora, Viticella, and cirrhosa, must not be omitted from a selection of the wild kinds. The new garden hybrids will also be useful.
