Pelargonidin is an anthocyanidin, a type of plant pigment producing a characteristic orange color used in food and industrial dyes.

It is the predominant pigment causing the red coloration in the spathes of Philodendron (Araceae).

The orange-coloured flowers of blue pimpernel (Anagallis monelli, Myrsinaceae) have a higher concentration of pelargonidin pigment.

Red and Pink Roses (Rosa) obtain their color from this phytochemical.

[8] Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea.
