Protea laetans, the Blyde River protea or Blyde sugarbush, is a species of flowering plant in the family Proteaceae. It was recognised as a species in 1970, and is endemic to the Blyde River Canyon of the Mpumalanga escarpment, South Africa.[1] The slender plants are up to 5m tall and flower from mid to late summer. The bracts of their closed flower heads are shiny and silvery in appearance.[1] They are most easily viewed near the F.H. Odendaal camp of the Blyde River Canyon Nature Reserve. Laetans means joyous, i.e. Blyde.
