Hymenocallis (Spider Lilies)
The spider lilies’ striking, fragrant summer blooms (July – September) attract nocturnal pollinators like the convolvulus hawkmoth (Agrius convolvuli) with their long-tubed, nectar-rich flowers. Though tropical in origin, their wetland affinity makes them ideal for pond margins or sheltered rain gardens, where their strappy leaves provide cover for aquatic invertebrates like damselfly nymphs. Planted in sun-warmed microclimates (e.g., south-facing walls), they sustain late-summer pollinators when other resources dwindle. Pair with UK-native Mentha aquatica to boost biodiversity, blending exotic flair with ecological function in wildlife-friendly water features.
