Cithara Buckwheat: A Rare California Native Annual Worth Knowing
If you’re hunting for truly unique native plants for your California garden, you might stumble across Cithara buckwheat (Eriogonum cithariforme var. agninum). This little-known annual is one of those plants that makes you feel like a botanical detective – there’s not a lot of information floating around about it, but what we do know makes it intriguing for native plant enthusiasts.
What Is Cithara Buckwheat?
Cithara buckwheat is an annual forb, which is just a fancy way of saying it’s a soft-stemmed flowering plant that completes its entire life cycle in one growing season. Unlike woody shrubs or trees, this plant stays herbaceous (think more like a wildflower than a bush) and dies back completely each year, relying on seeds to continue the next generation.
You might also see this plant listed under its scientific synonym, Eriogonum gracile var. polygonoides, in older botanical references – just different names for the same plant as taxonomists have refined their classifications over the years.
Where Does It Call Home?
This buckwheat is a true California native, endemic to the Golden State. While we know it’s found somewhere within California’s diverse landscapes, the exact counties and regions where it naturally occurs aren’t well-documented in readily available sources. This limited distribution information actually hints that it might be quite rare or have a very specific habitat range.
Should You Grow Cithara Buckwheat?
Here’s where things get a bit tricky. While Cithara buckwheat is undoubtedly a legitimate native plant that would theoretically make a great addition to a native California garden, the lack of detailed growing information presents some challenges for home gardeners.
The Reality Check
Let’s be honest – this isn’t going to be the plant you pick up at your local nursery. The limited documentation suggests that Cithara buckwheat is either:
- Extremely rare in the wild
- Has very specific habitat requirements
- Simply hasn’t been well-studied or cultivated
- Possibly difficult to establish in typical garden settings
What We Don’t Know (But Wish We Did)
Unfortunately, many practical gardening details remain mysteries for this particular buckwheat variety:
- Specific growing conditions and soil preferences
- Mature size and growth rate
- Flower appearance and blooming period
- Pollinator relationships and wildlife benefits
- Seed collection and propagation methods
- USDA hardiness zones (though being Californian, likely zones 8-10)
Better-Known Buckwheat Alternatives
If you’re drawn to the idea of native buckwheats but want something more garden-friendly and available, consider these well-documented California natives:
- California buckwheat (Eriogonum fasciculatum) – a reliable shrubby species
- Saint Catherine’s lace (Eriogonum giganteum) – spectacular white flower clusters
- Seaside buckwheat (Eriogonum latifolium) – great for coastal gardens
- Sulfur flower (Eriogonum umbellatum) – bright yellow blooms
The Bottom Line
Cithara buckwheat represents one of those fascinating native plants that reminds us how much we still don’t know about our local flora. While it’s certainly not invasive or problematic, the lack of cultivation information makes it more of a botanical curiosity than a practical garden choice for most home gardeners.
If you’re a serious native plant collector or researcher and happen to encounter seeds or plants from a reputable, legal source, it could be worth experimenting with – just don’t expect detailed growing guides or readily available plants. For most gardeners interested in supporting native ecosystems, the better-known buckwheat species will give you more reliable results and documented benefits for local wildlife.
Sometimes the most interesting plants are the ones that keep a few secrets, and Cithara buckwheat definitely falls into that category!
