Agropyron cristatum pectinatum var. imbricatum: A Mysterious Grass Variety

If you’ve stumbled across the name Agropyron cristatum pectinatum var. imbricatum in your gardening research, you’re likely wondering what exactly this plant is and whether it belongs in your garden. Well, you’re not alone in your curiosity – this particular grass variety is quite the enigma in the botanical world.

What We Know (And Don’t Know)

Agropyron cristatum pectinatum var. imbricatum is classified as a perennial grass, belonging to the diverse family of grasses and grass-like plants. It’s also known by the synonym Agropyron imbricatum Roem. & Schult. However, here’s where things get interesting – and a bit frustrating for plant enthusiasts like us.

This specific variety has very limited documentation in current botanical literature. While the parent species Agropyron cristatum (commonly known as crested wheatgrass) is well-studied, this particular variety designation appears to be either extremely rare, outdated, or possibly invalid according to modern taxonomic standards.

The Mystery of Missing Information

Unfortunately, we lack crucial information about this plant that would typically help gardeners make informed decisions:

  • Common names are unknown
  • Native range and distribution are unclear
  • Growing conditions and care requirements are undocumented
  • Wildlife and pollinator benefits are unspecified
  • Invasive or noxious status is undetermined

Should You Plant It?

Given the lack of reliable information about Agropyron cristatum pectinatum var. imbricatum, we’d recommend proceeding with caution. Without clear data on its native status, growing requirements, or potential ecological impacts, it’s difficult to provide responsible planting advice.

If you’re interested in this plant because you encountered it in old literature or seed catalogs, you might want to consider these alternatives:

  • Research the well-documented parent species, Agropyron cristatum, to see if it meets your needs
  • Consult with local native plant societies about appropriate grass alternatives
  • Work with reputable native plant nurseries who can suggest suitable native grasses for your region

A Word of Botanical Wisdom

This situation highlights an important lesson for gardeners: not every plant name you encounter will lead to a thriving garden addition. Sometimes the most responsible approach is to choose well-documented, locally appropriate alternatives rather than pursuing mysterious varieties with questionable provenance.

If you’re passionate about grasses and looking to add interesting species to your landscape, focus on native grasses that are well-suited to your region. Your local extension office or native plant society can point you toward beautiful, beneficial grass species that will thrive in your area while supporting local wildlife.

The Bottom Line

While Agropyron cristatum pectinatum var. imbricatum remains a botanical puzzle, your garden doesn’t have to be one. Choose plants with clear documentation, known benefits, and proven track records in gardens like yours. Your plants – and the wildlife that depends on them – will thank you for it.

Agropyron cristatum pectinatum var. imbricatum is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Agropyron cristatum pectinatum var. imbricatum is also known as:

Agropyron imbricatum & | USDA symbol: AGIM2

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
