Variation in Grevillea flower colour across Australia by Ben Raymond
Grevilleas are members of the Protea plant family and are widespread across Australia. Colour palettes of Grevillea flowers were extracted from photographs, and linked to occurrence records sourced from the Atlas of Living Australia (ala.org.au). The resultant distribution of flower colours shows a broad pattern of predominantly yellow in the north of Australia to red in the south. Red and orange flowered species are typically pollinated by birds; yellow- and cream-coloured species by insects.
