Digha Nikaya 1:1062
SUJATODibbānipi mandāravapupphāni antalikkhā papatanti, tāni tathāgatassa sarīraṁ okiranti ajjhokiranti abhippakiranti tathāgatassa pūjāya.
And the flowers of the heavenly Flame Tree fell from the sky, and they too sprinkled and bestrewed the Realized One’s body in honor of the Realized One.
