Nomenclature

The specific epithet is sometimes spelt cacaliaefolia in the literature; however, cacaliifolia is accepted as the correct spelling.[1] It means "with leaves like Cacalia[2] (a genus which has been renamed).

Description

It is an herbaceous perennial, blooming from midsummer to autumn with many pure gentian-blue flowers, about .5 inches long, with small green calyces. The leaves are grass-green in color with many hairs. The creeping rootstock spreads easily, forming clumps that are easily divided.[3] It grows well in a temperate climate. However it does not tolerate freezing temperatures, so must be given protection in cold wet winters. It is easily propagated by cuttings.[4]

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[4][5]
