What Makes It Special?

Mogollon Mountain lousewort is a perennial forb – essentially a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, it doesn’t develop thick, woody stems but instead maintains a more herbaceous character. This growth habit makes it perfect for filling in gaps in native plant gardens and adding texture to naturalized landscapes.

The plant belongs to a fascinating group that has adapted unique relationships with their environment, and like many members of the Pedicularis genus, it likely attracts specialized pollinators, particularly native bees.

Pedicularis angustifolia 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. Pedicularis angustifolia is also known as:

Pedicularis angustissima | USDA symbol: PEAN12

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.
