Golden Alexanders
Zizia aurea
Family Apiaceae
Golden Alexanders opens the pollinator year — flat golden umbels in spring, right when small native bees and beneficial insects emerge to find almost nothing else on the table. It isn't flashy; it's essential, the dependable first course of a well-fed garden.
Black swallowtail caterpillars use it as a host, and at an easy 1-2 ft it slips into rain gardens, borders, and meadow edges, self-sowing gently into a reliable patch. Adaptable to moist or average ground, sun or part shade — the definition of a foundation plant. Start your natives here.
