If you’re interested in growing Nevius’ garlic, please make sure to source it responsibly. This means:

  • Purchasing from reputable native plant nurseries that grow their own stock

  • Supporting nurseries that propagate plants ethically
  • Considering participating in seed collection programs when appropriate

Despite its rarity (or perhaps because of it), Nevius’ garlic offers several compelling reasons to include it in your native plant collection:

  • True native authenticity: You’ll be growing a plant that truly belongs in Pacific Northwest ecosystems
  • Pollinator support: Like other alliums, it likely attracts beneficial small pollinators

  • Sun exposure: Probably prefers full sun to partial shade
  • Water: Moderate moisture during growing season, drier conditions during dormancy

Allium nevii 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. Allium nevii is also known as:

Allium douglasii var. nevii Ownbey & | USDA symbol: ALDON

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.
