Ricegrass (Oryzopsis holciformis): A Mysterious Grass with an Uncertain Identity
If you’ve stumbled across the name Oryzopsis holciformis while researching native grasses for your garden, you might find yourself scratching your head – and for good reason! This particular ricegrass presents quite the botanical puzzle that even experienced gardeners and botanists find perplexing.
The Mystery Behind the Name
Here’s where things get interesting (and a bit frustrating): Oryzopsis holciformis appears to be what botanists call a phantom species. Despite extensive searching through botanical databases, scientific literature, and horticultural resources, this exact species name doesn’t appear in any reliable sources. It’s like trying to find a ghost!
The genus Oryzopsis itself has been through quite the taxonomic shuffle over the past few decades. Many species that were once classified as Oryzopsis have been moved to other genera like Achnatherum, Piptatherum, or Stipa as scientists better understand the relationships between different grass species.
What We Do Know About Ricegrasses
While we can’t provide specific details about Oryzopsis holciformis, we can tell you that ricegrasses as a group are fascinating plants. They’re typically:

A Word of Caution for Gardeners
If you’re considering planting something labeled as Oryzopsis holciformis, we’d strongly recommend doing some detective work first. Here’s what you should do:
- Ask your supplier for verification of the plant’s true botanical name
