Wildlife and Ecosystem Benefits

Beyond its garden appeal, common eyebright supports local ecosystems by providing nectar and pollen for small pollinators. The plant’s flowers are particularly attractive to native bees and beneficial flies, making it a valuable addition to any pollinator-friendly garden.

Is Common Eyebright Right for Your Garden?

Common eyebright is an excellent choice if you’re looking to create a naturalized garden space, live in a cooler climate, and appreciate subtle beauty over flashy displays.

Whether you’re creating a woodland sanctuary or adding authentic touches to a wildflower meadow, common eyebright offers a delightful way to bring a bit of northern wilderness charm to your garden space.

Euphrasia nemorosa is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Euphrasia nemorosa is also known as:

Euphrasia americana auct. p.p. | USDA symbol: EUAM6
Euphrasia arctica Lange ex ssp. borealis | USDA symbol: EUARB
Euphrasia borealis | USDA symbol: EUBO7
Euphrasia canadensis auct. non | USDA symbol: EUCA14
Euphrasia curta | USDA symbol: EUCU6
Euphrasia pectinata auct. non | USDA symbol: EUPE20
Euphrasia tatarica auct. non ex | USDA symbol: EUTA2

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
