Ale: Hawaii’s Rare and Precious Native Plantain

Meet ale (Plantago princeps var. longibracteata), one of Hawaii’s most elusive botanical treasures. This unassuming little perennial herb might not catch your eye like a flashy hibiscus, but it holds a special place in the islands’ native plant community—and unfortunately, it’s hanging on by a thread.

What Makes Ale Special?

Ale is a native Hawaiian variety of plantain that belongs to a group of plants you might know better as the common weeds that pop up in sidewalk cracks. But don’t let that fool you—this particular variety is nothing like those tough, cosmopolitan cousins. As a forb herb, ale is a soft-stemmed perennial that lacks woody tissue and keeps its growing points close to or below ground level, helping it survive in its specialized habitat.

Where Does Ale Call Home?

This rare plantain is endemic to Hawaii, meaning it exists nowhere else on Earth. You’ll only find ale growing naturally within the Hawaiian Islands, where it has evolved to thrive in the unique conditions found there.

A Plant in Peril

Here’s where things get serious, fellow plant lovers. Ale carries a Global Conservation Status of S1T1, which means it’s critically imperiled. This isn’t a plant you can casually add to your garden wishlist—it’s fighting for survival in the wild, and every individual matters for the species’ future.

Should You Grow Ale?

The short answer is: probably not, and here’s why. Given ale’s critically endangered status, this plant needs our protection more than our cultivation. Instead of trying to grow ale in your garden, consider these alternatives:

  • Support Hawaiian native plant conservation organizations
  • Visit botanical gardens that specialize in Hawaiian native plants
  • Choose other native Hawaiian plants that are more stable for home cultivation
  • Learn about and advocate for habitat protection in Hawaii

If You’re Lucky Enough to Encounter Ale

Should you find yourself in Hawaii and spot what might be ale in the wild, resist the urge to collect seeds or take cuttings. Instead:

  • Observe and photograph (without disturbing the plant)
  • Report your sighting to local botanists or conservation groups
  • Enjoy the privilege of seeing one of Hawaii’s rarest plants in its natural habitat

The Bigger Picture

Ale’s story reminds us that native plants aren’t just pretty additions to our gardens—they’re irreplaceable pieces of their ecosystems’ puzzles. While we can’t all grow ale in our backyards, we can all play a role in protecting Hawaii’s incredible plant diversity by supporting conservation efforts and choosing responsibly sourced native plants for our own gardens.

Sometimes the best way to love a plant is to let it be wild and work to ensure it stays that way for future generations to discover and appreciate.

Plantago princeps var. longibracteata 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. Plantago princeps var. longibracteata is also known as:

Plantago princeps & var. acaulis | USDA symbol: PLPRA
Plantago princeps & var. elata | USDA symbol: PLPRE

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.
