Mogollon Mountain Lousewort: A Rare Native Gem Worth Protecting

Meet the Mogollon Mountain lousewort (Pedicularis angustifolia), a native perennial that’s as intriguing as its name suggests. Don’t let the lousewort part put you off – this plant got its quirky common name from old folklore, not from any actual association with pests. In fact, this little-known native is quite the opposite of a pest – it’s a rare treasure that deserves our attention and protection.

A Plant in Need of Friends

Before we dive into growing tips, here’s something important you need to know: Mogollon Mountain lousewort is classified as S2, which means it’s imperiled in the wild. With only 6 to 20 known occurrences and fewer than 1,000 to 3,000 individuals remaining, this species is dancing on the edge of rarity. If you’re considering adding this plant to your garden, you’re not just choosing a unique native – you’re becoming part of a conservation effort.

Where Does It Call Home?

This specialized native calls New Mexico home, where it has adapted to specific environmental conditions over thousands of years. As a true native of the lower 48 states, it plays an important role in its local ecosystem, even if we don’t see it very often.

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.

Should You Grow It?

Here’s where things get interesting. While we absolutely encourage growing native plants, Mogollon Mountain lousewort comes with special considerations:

  • Conservation impact: Growing this rare species can contribute to conservation efforts
  • Unique addition: You’ll have one of the rarest plants in any neighborhood garden
  • Native ecosystem support: Even in gardens, it can support local wildlife
  • Educational value: Perfect conversation starter about native plant conservation

The Responsible Growing Approach

If you decide to grow Mogollon Mountain lousewort, responsibility is key. Here are the essential guidelines:
