The Mystery of Zigadenus volcanicus: A Plant That May Not Exist

If you’ve stumbled upon the name Zigadenus volcanicus in your gardening research, you’re not alone in wondering about this mysterious plant. Here’s the thing though – this particular species name appears to be something of a botanical ghost story.

What’s in a Name?

The genus Zigadenus has had quite the taxonomic rollercoaster ride over the years. Many plants that were once classified as Zigadenus species have been shuffled around to different genera as botanists have gotten better at understanding plant relationships through genetic analysis. It’s like a massive botanical reorganization project that’s been going on for decades!

Unfortunately, Zigadenus volcanicus doesn’t appear in any current botanical databases or scientific literature that I can find. This could mean a few things:

  • It might be an outdated name that’s no longer recognized
  • It could be a misidentification or typographical error
  • It might be an informal name that never gained official botanical recognition

The Zigadenus Shuffle

If you’re interested in plants that were formerly called Zigadenus, you’ll want to look into genera like Anticlea and Toxicoscordion instead. These plants, commonly known as death camas, are fascinating but definitely not for the casual gardener – they’re highly toxic!

What Should You Do?

If you came across Zigadenus volcanicus somewhere and were hoping to add it to your garden, I’d recommend:

  • Double-checking your source – there might be a typo in the name
  • Looking into legitimate native plant alternatives in the lily family
  • Consulting with local botanical experts or extension services
  • Exploring well-documented native bulbs and perennials instead

Better Safe Than Sorry

When it comes to plants with uncertain identities, especially those potentially related to toxic species, it’s always better to stick with well-documented, properly identified plants. Your local native plant society or botanical garden can point you toward beautiful, legitimate native options that will thrive in your area and support local wildlife.

Sometimes the most interesting garden stories are about the plants we almost grew, rather than the ones we did!
