This is a compact "Jacobís ladder" variety that, as the cultivar name suggests, features purple tinted, green leaves and burgundy stems with clusters of slightly fragrant cobalt-blue flowers. Leaves appear ladder-like in structure, hence the common name. They have a stronger purple hue in cooler weather.

Purplish foliage and blue flowers will brighten shady locations in borders, woodland gardens, cottage gardens or shade gardens.
Prefers cool partial shade in the hottest summer months, with free draining soil or compost. Prefers rich, humusy, consistently moist soils that do not dry out.
A hardy plant which should survive normal winter conditions outside, especially if protected from the hardest frosts.
Plants may be cut back to basal foliage after flowering or if foliage declines to tidy the planting and to encourage a possible late summer rebloom.
