One plant, many pollinators
My brother’s yard which slopes down to an inlet of the ocean and has boggy areas has native plants galore. Interestingly, rattlesnake master, originally indigenous to prairie-like ecosystems in the eastern U S, flourishes in those beds but as long as it has good sun can happily grow in a variety of soils. It has tall, maybe four feet, stalks that holds flower heads, usually a handful on well-established plants. Each inflorescence has over a hundred tiny flowers providing both nectar and pollen for insects. Many people get most excited about butterflies on their pollinator plants, but Eryngium yuccafolium, flowering late summer, perhaps attracts a larger diversity of visitors than almost any other insect magnet. According to the Xerces society website --bumble bees, yellow-faced bees, sweet bees, multiple beetles and dozens of fly species.
