Flatleaf bladderwort is an aquatic carnivorous plant that must be grown in still, shallow water or wet boggy conditions with very low nutrient levels — avoid fertilizing, as enriched water will harm it. It catches tiny aquatic invertebrates using its specialized bladder traps and thrives best in full sun to partial shade outdoors in a pond or bog garden. This plant is best suited to experienced aquatic or carnivorous plant enthusiasts rather than general home gardeners.
