Rarely offered, Lobelia tupa is a very stately perennial with whorls of soft sage green leaves that bear stout, upright dark red flower stems carry long tubular brick red flowers over a long period from mid-summer.
This is a really special plant that is suited to a free-draining, sheltered site in full sun. Reasonably drought tolerant but will require occasional watering over summer.
Winter dormant - protect from frost.
Height with flower stems 1.5-2m x up to 1 metre over time
