Erigeron gaudinii: A Mysterious Member of the Fleabane Family

If you’ve stumbled across the name Erigeron gaudinii while researching native plants, you’ve encountered one of botany’s little mysteries. This particular species name doesn’t appear in most standard botanical databases, leaving gardeners scratching their heads and wondering if they’ve discovered a hidden gem or hit a taxonomic dead end.

The Case of the Elusive Erigeron

Here’s where things get interesting (and a bit frustrating): Erigeron gaudinii seems to exist in that botanical twilight zone where species names float around without clear documentation. While the genus Erigeron is well-established and includes many wonderful native wildflowers commonly known as fleabanes, this particular species epithet gaudinii doesn’t show up in major plant databases or taxonomic resources.

This could mean several things:

  • It might be an outdated or synonymized name that’s been reclassified
  • It could be a very localized or rare species with limited documentation
  • The name might be a misidentification or typo of another Erigeron species

What We Know About the Erigeron Family

While we can’t pin down specifics about E. gaudinii, we can tell you that the Erigeron genus is home to some fantastic native wildflowers. These plants, commonly called fleabanes, are members of the sunflower family and typically feature daisy-like flowers with numerous thin petals radiating from yellow centers.

Most Erigeron species share these characteristics:

  • Daisy-like flowers that bloom from late spring through fall
  • Excellent pollinator plants that attract bees, butterflies, and beneficial insects
  • Generally low-maintenance once established
  • Drought-tolerant and adaptable to various soil conditions

The Geographic Mystery

Without clear documentation, we cannot determine where Erigeron gaudinii might naturally occur or if it’s truly native to any particular region. This uncertainty makes it impossible to provide specific recommendations about its use in native plant gardens.

A Gardener’s Dilemma

So, should you plant Erigeron gaudinii? Here’s our honest take: until there’s clearer botanical documentation, we’d recommend steering toward well-documented Erigeron species instead. There are plenty of beautiful, proven native fleabanes that will give you all the benefits you’re looking for without the taxonomic uncertainty.

Better Bets: Documented Erigeron Species

If you’re drawn to the fleabane family, consider these well-documented alternatives:

  • Erigeron speciosus (Showy fleabane) – gorgeous purple-pink flowers
  • Erigeron annuus (Annual fleabane) – white daisy-like blooms
  • Erigeron philadelphicus (Philadelphia fleabane) – delicate pink flowers
  • Erigeron strigosus (Prairie fleabane) – white flowers with yellow centers

The Bottom Line

While botanical mysteries like Erigeron gaudinii can be intriguing, successful native gardening relies on choosing plants with clear provenance and well-understood growing requirements. Rather than gambling on an uncertain species, invest your garden space in documented native fleabanes that will reliably provide beauty, pollinator support, and ecological benefits.

If you do encounter plants sold as Erigeron gaudinii, ask detailed questions about their source and consider having them identified by a local botanist or extension office. Sometimes these taxonomic puzzles lead to interesting discoveries – but more often, they’re simply cases of mistaken identity that are better resolved before planting.
