Siskiyou Pennycress: A Rare Oregon Native Worth Knowing
Meet Siskiyou pennycress (Noccaea fendleri siskiyouensis), a fascinating little native plant that calls Oregon home. While this perennial forb might not be the showiest addition to your garden, it represents something special – a piece of Oregon’s unique botanical heritage that deserves our attention and respect.
What Makes Siskiyou Pennycress Special?
This native Oregon plant belongs to the mustard family and grows as a herbaceous perennial forb. Unlike woody shrubs or trees, Siskiyou pennycress lacks significant woody tissue above ground, instead relying on underground structures to survive from year to year. It’s one of those quiet, understated natives that might not catch your eye immediately but plays an important role in Oregon’s natural ecosystems.
Where You’ll Find It Growing Wild
Siskiyou pennycress has a very limited native range, found only in Oregon. This restricted distribution makes it particularly precious from a conservation standpoint.

A Word of Caution: Rarity Matters
Here’s something important every gardener should know: Siskiyou pennycress has a conservation status of S5T3, indicating it’s considered rare or uncommon. This means if you’re thinking about adding this plant to your garden, you’ll want to be extra careful about sourcing.
If you decide to grow Siskiyou pennycress:
- Only purchase from reputable native plant nurseries that ethically propagate their stock
- Never collect plants or seeds from wild populations
- Consider whether other more common Oregon natives might better serve your garden’s needs
Growing Siskiyou Pennycress: What We Know
Unfortunately, specific growing information for this rare subspecies is limited. As a native Oregon forb, it likely prefers conditions similar to its natural habitat, but without detailed cultivation data, growing this plant successfully might require some experimentation and patience.
What we do know is that it’s a perennial, meaning once established, it should return year after year. Like many native forbs, it probably has specific soil and moisture requirements that mirror its wild growing conditions.
Should You Plant It?
While Siskiyou pennycress is undoubtedly an interesting native plant, its rarity raises some important questions for home gardeners. Unless you have a specific interest in rare Oregon natives and access to ethically sourced plants, you might want to consider other native options that can provide similar ecological benefits without the conservation concerns.
Oregon has many wonderful native forbs that are more readily available and better suited to home gardens. Consider exploring other members of the mustard family or consulting with local native plant societies about alternatives that might better serve both your garden goals and conservation efforts.
The Bottom Line
Siskiyou pennycress represents the kind of botanical treasure that makes Oregon’s flora so special. While it might not be the best choice for every garden, knowing about plants like this helps us appreciate the incredible diversity of native species in our region. Whether you choose to grow it or simply appreciate it from afar, Siskiyou pennycress reminds us why protecting native plant habitats is so important.
If you do decide to pursue growing this rare native, make sure you’re doing so responsibly and consider connecting with local botanical organizations or native plant societies who might have more specific cultivation advice.
