Nutational selenotropism, the rhythmic movement of plants in response to moonlight, is a captivating phenomenon for garden lovers. Outdoor plant boxes provide an ideal setting to observe this behavior. Among the best plants to showcase this trait are moonflowers (Ipomoea alba) and sunflowers (Helianthus annuus).

Moonflowers are renowned for their nocturnal blooming and subtle movements tracking the moon’s path. Their large, white flowers unfurl at dusk, making them a striking choice. Sunflowers, though primarily heliotropic, also exhibit minor nutational movements under moonlight, adding dynamic interest to plant boxes.

Other contenders include evening primrose (Oenothera biennis) and night-blooming cereus (Epiphyllum oxypetalum), which display similar lunar-responsive traits. For optimal results, ensure your plant boxes receive ample moonlight and are positioned away from artificial light interference.

By selecting these plants, you can create a mesmerizing moonlit garden that highlights the wonders of nutational selenotropism.
