Ale (Plantago princeps var. anomala): Hawaii’s Rare Native Plantain
Meet one of Hawaii’s most elusive native plants – the ale, scientifically known as Plantago princeps var. anomala. This isn’t your typical garden center find, and there’s a very good reason why you’ve probably never heard of it. This little Hawaiian endemic is so rare that it holds a conservation status that should make any gardener pause and think twice.
What Makes Ale Special?
Ale is a perennial forb herb, which simply means it’s a non-woody plant that comes back year after year. Like other members of the plantain family, it’s a relatively humble-looking plant that you might easily overlook in the wild. But don’t let its unassuming appearance fool you – this plant is a true Hawaiian treasure.
As a native species found exclusively in Hawaii, ale represents millions of years of evolution in isolation. It’s part of the unique flora that makes the Hawaiian Islands such a special place for biodiversity.
Where Does Ale Grow?
This rare variety is endemic to Hawaii, meaning it grows naturally nowhere else on Earth. Its distribution is limited to specific locations within the Hawaiian Islands, making it an incredibly localized species.
The Conservation Reality Check
Here’s where things get serious. Ale has a Global Conservation Status of S1T1, which translates to critically imperiled. This means the plant is at extremely high risk of extinction, with very few known populations remaining in the wild. When a plant reaches this level of rarity, every individual becomes precious.
Should you plant ale in your garden? The short answer is: probably not, unless you’re involved in serious conservation efforts. Here’s why:
- Extremely limited wild populations make conservation the top priority
- Specialized growing requirements that are poorly understood
- Risk of removing plants from already vulnerable wild populations
- Responsibility to leave conservation to qualified professionals
If You’re Determined to Help
If you’re passionate about Hawaiian native plants and want to contribute to ale’s conservation, here are responsible approaches:
- Support local botanical gardens and conservation organizations
- Participate in habitat restoration projects
- Choose other native Hawaiian plants that are more abundant
- Only obtain plants through legitimate conservation programs
Growing Conditions and Care
Little is documented about ale’s specific growing requirements, which is partly why it’s so challenging to cultivate. As a Hawaiian endemic, it likely requires:
- Tropical conditions (USDA zones 10-11)
- Specific soil conditions found in its native habitat
- Careful attention to moisture and drainage
- Protection from invasive species competition
The lack of detailed cultivation information isn’t accidental – it reflects how few people have successfully grown this plant and how little we still know about its needs.
Better Alternatives for Your Garden
Instead of trying to grow this rare gem, consider these more common native Hawaiian plants that will give you that authentic island feel without conservation concerns:
- Other Plantago species that are more abundant
- Native Hawaiian grasses and sedges
- Common native forbs and herbs
- Native shrubs and trees suitable for your garden size
The Bottom Line
Ale represents the delicate balance between our desire to grow native plants and our responsibility to protect endangered species. While it’s natural to want to cultivate rare and special plants, sometimes the best thing we can do is appreciate them from afar and focus our gardening efforts on species that can benefit from cultivation without risk.
If you’re drawn to Hawaiian native plants, there are plenty of wonderful options that won’t compromise conservation efforts. Your local native plant society or botanical garden can point you toward Hawaiian natives that are both appropriate for home cultivation and beneficial for local ecosystems.
Remember: the rarest plants often need our protection more than our cultivation. Sometimes the most loving thing we can do for a plant is to let the experts handle its care while we support conservation efforts from the sidelines.
