International Sunflower Guerrilla Gardening Day is celebrated on the first Saturday of May each year. This day encourages individuals and communities to plant sunflowers in neglected or abandoned urban spaces. The goal is to beautify these areas while promoting environmental awareness and community engagement. Participants often gather to share resources, knowledge, and enthusiasm for gardening. By planting sunflowers, they aim to create vibrant green spaces that attract pollinators and improve local ecosystems. This grassroots movement highlights the importance of urban gardening and encourages people to take action in their neighborhoods.
