Sunflowers in the Rainforest? No—They’re Temperate Natives

Sunflowers (Helianthus annuus) are native to North America and thrive in temperate, sunny, well‑drained habitats. Rainforests—hot, humid, shaded, with intense competition—are ecologically unsuitable. Rainforest flora includes towering trees, epiphytes (orchids, bromeliads), ferns, and shade‑tolerant understory plants, not sun‑loving annuals like sunflowers.
