Harford’s Ragwort: A Pacific Northwest Native Worth Discovering

If you’re passionate about native plants and looking to add some authentic Pacific Northwest character to your garden, Harford’s ragwort (Packera bolanderi var. harfordii) might just be the hidden gem you’ve been searching for. This perennial forb brings a touch of wild beauty straight from the forests and meadows of Oregon and Washington to your landscape.

What Makes Harford’s Ragwort Special?

Harford’s ragwort is a true Pacific Northwest native, belonging to the diverse Packera genus (formerly classified under Senecio). As a perennial forb, this plant returns year after year, developing its herbaceous growth from buds at or below ground level. Unlike woody shrubs or trees, it maintains a soft, non-woody structure that makes it perfect for adding texture to native plant gardens.

A Word About Rarity

Here’s something important to keep in mind: Harford’s ragwort has a somewhat uncertain conservation status.

Growing Tips and Considerations

Since detailed cultivation information for this specific variety is scarce, your best bet is to mimic its natural Pacific Northwest habitat conditions. This likely means providing well-draining soil and conditions similar to what you’d find in Oregon and Washington’s native plant communities.

Given the limited available information about specific growing requirements, consider reaching out to local native plant societies, botanical gardens, or university extension services in Oregon and Washington for more detailed cultivation advice.

The Bottom Line

Harford’s ragwort represents an opportunity to grow something truly special and regionally authentic in your Pacific Northwest garden.

Packera bolanderi var. harfordii 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. Packera bolanderi var. harfordii is also known as:

Senecio bolanderi Gray var. harfordii | USDA symbol: SEBOH
Senecio harfordii | USDA symbol: SEHA10

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.
