The Mystery of Erigeron alpinus intermedius: When Plant Names Leave Us Puzzled

Every once in a while, even experienced gardeners and botanists encounter a plant name that sends them on a wild goose chase through field guides and botanical databases. Erigeron alpinus intermedius appears to be one of those enigmatic names that doesn’t quite match up with recognized botanical nomenclature.

What We Know (And Don’t Know)

Here’s the thing about plant names – they follow strict scientific rules, and when something doesn’t fit the established system, it raises some red flags. After digging through botanical databases, horticultural resources, and scientific literature, Erigeron alpinus intermedius doesn’t appear to be a currently recognized plant name in the scientific community.

The genus Erigeron, commonly known as fleabanes, is certainly real and includes many wonderful native species across North America. These daisy-like wildflowers are beloved by pollinators and gardeners alike. However, this particular trinomial (three-part) name doesn’t match standard botanical naming conventions or appear in authoritative plant databases.

Could This Be a Case of Mistaken Identity?

If you’ve encountered this name somewhere, it might be:

  • A misprint or transcription error of another Erigeron species
  • An outdated or invalid botanical name
  • A regional common name that got mixed up with scientific nomenclature
  • Part of a larger taxonomic revision that hasn’t been widely adopted

What to Do Instead

Rather than chase after this botanical ghost, consider exploring some of the many wonderful, well-documented native Erigeron species that could bring beauty and ecological value to your garden:

  • Erigeron speciosus (Showy fleabane) – gorgeous purple-pink daisy flowers
  • Erigeron glaucus (Seaside daisy) – perfect for coastal gardens
  • Erigeron compositus (Cut-leaved daisy) – delicate, finely divided foliage
  • Erigeron peregrinus (Wandering daisy) – lovely mountain native

The Takeaway for Gardeners

This little botanical mystery serves as a good reminder to always verify plant names through reputable sources before making purchasing decisions. When in doubt, consult local extension services, native plant societies, or established botanical references.

If you have more information about where you encountered this name or believe it might be a valid species I’ve missed, I’d love to hear from you! Gardening is all about learning from each other, and sometimes the most interesting discoveries come from following these puzzling trails.

In the meantime, there are plenty of confirmed, beautiful native fleabanes waiting to grace your garden with their cheerful daisy faces and pollinator-friendly blooms. Happy gardening!
