Johnston’s Cryptantha: A Rare Utah Native Worth Knowing
If you’re a native plant enthusiast with a soft spot for rare treasures, Johnston’s cryptantha (Cryptantha johnstonii) might just capture your attention. This little-known perennial herb represents one of Utah’s unique botanical gems, though finding information—or the plant itself—can be quite the challenge.
What Is Johnston’s Cryptantha?
Johnston’s cryptantha is a perennial forb, which simply means it’s a non-woody plant that comes back year after year. As a member of the borage family, it shares characteristics with other Cryptantha species, though this particular variety has carved out its own special niche in the plant kingdom.
Unlike shrubs or trees, this herb lacks significant woody tissue and keeps its growing buds at or below ground level—a smart survival strategy for weathering tough conditions.
Where Does It Call Home?
Here’s where things get interesting (and a bit concerning): Johnston’s cryptantha is native to Utah and appears to be found nowhere else in the wild. This extremely limited geographic distribution makes it quite the botanical rarity.
Why the Rarity Matters
This plant carries a conservation status of S1S2, which indicates it’s considered rare to very rare. For gardeners and native plant enthusiasts, this presents both an opportunity and a responsibility. While growing rare natives can contribute to conservation efforts, it’s crucial to source any plants or seeds responsibly.
Should You Grow Johnston’s Cryptantha?
The honest answer? It’s complicated. Here’s what to consider:
- Conservation value: Growing rare natives can help preserve genetic diversity
- Sourcing challenges: Finding this plant through commercial sources is extremely unlikely
- Limited information: Specific growing requirements aren’t well documented
- Responsible practices: Any material should come from ethical, conservation-minded sources
If You’re Determined to Try
Given the lack of specific growing information for Johnston’s cryptantha, your best bet is to mimic the conditions where other Cryptantha species thrive. Most members of this genus prefer:
- Well-draining, sandy or rocky soils
- Full sun exposure
- Low to moderate water requirements
- Hardy conditions typical of high desert environments
Alternative Options
If you’re drawn to the idea of growing Cryptantha species but can’t source Johnston’s cryptantha responsibly, consider these more readily available relatives:
- White forget-me-not (Cryptantha confertiflora)
- Narrowstem cryptantha (Cryptantha angustifolia)
- Other native Utah forbs that share similar growing conditions
The Bottom Line
Johnston’s cryptantha represents the fascinating world of rare native plants—species that remind us how much we still have to learn about our local ecosystems. While it might not be the easiest plant to add to your garden, knowing it exists enriches our understanding of Utah’s unique botanical heritage.
If you do encounter this rare gem, whether in the wild or through conservation sources, treat it with the respect it deserves. After all, plants this rare are living links to the intricate web of life that makes each region unique.
