This showy perennial has lanceolate, light green leaves. The erect stems produce lavender-blue, tubular flowers crowded together on the upper part. The species name is based on the fact that it was a supposed cure for syphilis.
Repotting or planting
9cm marginal plants require potting into a larger mesh basket. Place in a pond no deeper than 1/3 maximum recommended planting depth to allow the plants to establish. 1ltr marginal plants do not require repotting, place in the pond no deeper than 1/2 maximum recommended planting depth to allow the plants to establish. 3ltr and 5ltr plants do not require repotting, as they are larger more established plants they can be placed up to the maximum recommended depth. There is no need to remove the mesh basket.
Little maintenance is required. Trim to tidy but leave foliage to die back naturally to encourage winter bud formation
