Any plant that requires abundant sunlight to grow and thrive, typically found in open, sunny habitats.
From Greek helios (sun) + -phyte (plant, from phyton meaning 'plant'). The -phyte suffix became standard in botany for naming plant types during the 18th and 19th centuries.
Sunflowers, cacti, and wheat are classic heliophytes—and because they're adapted to intense light, they actually have fewer stomata (pores) on their leaves to conserve water, making them drought-tolerant too!
