Oblanceolate or obovate leaves, about 6-30 per plant, form either a basal rosette with stems absent or in terminal rosettes when plant stems are present.

Inflorescences are 10–25 cm long and produce pink flowers that bloom from November to April in their native range.

S. paniculatum is endemic to eastern Australia from Dalveen, Queensland to Tenterfield, New South Wales at elevations of 800 to 1000 metres.

Its typical habitat has been reported as moist sandy soils on granite substrates along creeks, drains, or low-lying flats.

It differs from S. debile by the lack of bracteoles and its paniculate inflorescence.
