Ball Draba: A Rare Nevada Native Worth Protecting

Meet ball draba (Draba sphaeroides), one of Nevada’s most elusive native wildflowers. This little-known perennial forb represents the kind of botanical treasure that makes native plant enthusiasts’ hearts skip a beat – rare, endemic, and shrouded in just enough mystery to keep things interesting.

What Makes Ball Draba Special

Ball draba is a perennial forb, which simply means it’s a non-woody flowering plant that comes back year after year. As a member of the mustard family (like many Draba species), it lacks the thick, woody stems of shrubs and trees, instead growing as a herbaceous plant with its growing points at or below ground level.

Where You’ll Find Ball Draba

This Nevada native has a very limited range, found only within the Silver State’s borders. Its restricted distribution makes it a true endemic species – a botanical local celebrity, if you will.

A Rare Beauty That Needs Our Help

Here’s where things get serious: ball draba carries a Global Conservation Status of S2S3, which means it’s considered imperiled to vulnerable. In plain English, this plant is rare enough that we need to be thoughtful about its conservation. This isn’t your everyday garden center find – it’s a species that deserves our respect and protection.

Should You Grow Ball Draba?

The short answer is: maybe, but with important caveats. If you’re lucky enough to encounter ball draba or seeds from this species, here’s what you need to know:

  • Only obtain plants or seeds from reputable native plant societies or conservation organizations
  • Never collect from wild populations
  • Consider it a conservation project rather than typical gardening
  • Connect with Nevada native plant groups for guidance

The Mystery of Growing Ball Draba

Unfortunately, detailed cultivation information for ball draba is scarce – a common situation with rare native species that haven’t been widely studied or cultivated. What we do know is that as a Nevada native, it’s adapted to the state’s challenging growing conditions, which typically include:

  • Low rainfall and drought tolerance
  • Temperature extremes
  • Well-draining soils
  • High elevation conditions (possibly)

Alternative Native Options

If you’re drawn to rare Nevada natives but want something more available and better understood, consider exploring other native Draba species or Nevada forbs that offer similar ecological benefits without the conservation concerns. Your local native plant society can point you toward appropriate alternatives that won’t put pressure on wild populations.

The Bottom Line

Ball draba represents the fascinating world of rare native plants – species that remind us how much we still don’t know about our local flora. While it may not be the easiest addition to your garden, it serves as an important reminder of Nevada’s unique botanical heritage and the importance of plant conservation efforts.

If you do encounter this rare beauty, consider yourself fortunate to witness a piece of Nevada’s natural history. And if you’re interested in growing rare natives, connect with conservation organizations who can guide you toward responsible ways to participate in preserving these botanical treasures for future generations.
