Abstract
Passionflower (Passiflora incarnata), Tennessee’s state wildflower, is valued for its ecological role as a pollinator plant and its historical significance to the Cherokee, making it an ideal candidate for green roofs that support biodiversity and urban sustainability. This study examined the feasibility of growing passionflower on a green roof and tested whether commercial fertilizer (Miracle-Gro) or natural compost would lead to greater growth compared to no fertilizer. Twelve plants were divided equally into three treatment groups: control, Miracle-Gro, and compost, with growth measurements taken weekly from September to November. Results suggest that passionflowers treated with Miracle-Gro achieved the most growth, outperforming both compost and control plants. These findings indicate that commercial fertilizer may optimize growth on green roofs, promoting better plant health in urban settings. By establishing passionflower as a viable green roof species, this study supports its use in urban greening and highlights its role in sustainable landscaping and cultural preservation in Tennessee.
