The buds of Dilatris corymbosa often start off red brown as here in the centre of the flat-topped, many-flowered inflorescence. There are spaced, triangular bracts on the hairy flower stem. Appearing like a panicle, suggested by the specific name to be a corymb, the structure is a thyrse, its branches shaggy-haired.
The flowers start opening from the outside of the inflorescence, turning mauve to blue on the outside tepal surfaces and lighter, nearly white inside (Manning, 2007; Bean and Johns, 2005; Bond and Goldblatt, 1984; iNaturalist; https://www.worldfloraonline.org).
