The rounded inflorescence shape of Buddleja saligna is lost as the head becomes darker, eventually also losing its proud, upright posture.
The brown husks of the calyces remain around the developing fruits when flowering is over. Difficult to see here, the upper half of the fruit capsules protrude above the sepals. Tiny seeds, oblong and compressed, are produced (Coates Palgrave, 2002; Leistner, (Ed.), 2000; Pooley, 1993; iNaturalist).
