Tender Green (Brassica perviridis): A Mystery Plant Worth Investigating

If you’ve stumbled across the name tender green or its botanical moniker Brassica perviridis while researching plants for your garden, you’re not alone in wondering what exactly this plant is. Here’s the thing – this particular plant name exists in something of a botanical gray area, making it a bit of a mystery for gardeners and plant enthusiasts alike.

What We Know (And Don’t Know) About Tender Green

Brassica perviridis, commonly called tender green, has limited documentation in standard botanical references. What we do know is that it has a synonym: Brassica rapa L. var. perviridis L.H. Bailey, which suggests it may be a variety of the more common field mustard or turnip (Brassica rapa). However, finding reliable, specific information about this particular plant proves surprisingly challenging.

The lack of clear documentation about its native status, geographical distribution, and growing characteristics makes it difficult to provide definitive guidance about whether and how to grow this plant in your garden.

The Challenge with Uncommon Plant Names

Sometimes in the plant world, names get passed around without clear documentation, or plants may be regional varieties that haven’t been thoroughly studied or cataloged. This appears to be the case with Brassica perviridis. Without reliable information about:

  • Its true native range and status
  • Specific growing requirements
  • Mature size and growth habits
  • USDA hardiness zones
  • Potential invasive characteristics
  • Wildlife and pollinator benefits

It becomes nearly impossible to make informed recommendations about growing this plant.

A Word of Caution for Gardeners

When you encounter a plant with limited documentation like tender green, it’s wise to proceed with caution. Without knowing its native status, growth habits, or potential for invasiveness, planting unknown species could potentially:

  • Introduce non-native plants to your local ecosystem
  • Create maintenance challenges if the plant has aggressive growth habits
  • Disappoint you if the plant doesn’t perform as expected

Better Alternatives for Your Garden

If you’re looking for members of the Brassica family that are well-documented and garden-worthy, consider these alternatives:

  • Native mustards and their cultivars that are appropriate for your region
  • Well-established Brassica vegetables like kale, collards, or arugula
  • Native wildflowers that provide similar ecological benefits

The Bottom Line

While the name tender green sounds appealing for any garden, the lack of reliable information about Brassica perviridis makes it a risky choice for most gardeners. When in doubt, it’s always better to choose well-documented native plants or established garden varieties that you know will thrive in your specific conditions and support local wildlife.

If you’re determined to learn more about this mysterious tender green, consider reaching out to botanical institutions, university extension services, or native plant societies in your area. They might have regional knowledge about this elusive plant that isn’t readily available in standard references.

Remember, successful gardening is often about choosing the right plant for the right place – and that’s much easier to do when you have reliable information about your plant choices!
