Kingdevil: A Plant Shrouded in Mystery

If you’ve stumbled across the name kingdevil (Hieracium praealtum var. praealtum) in your gardening research, you’re probably scratching your head wondering what exactly this plant is. Don’t worry – you’re not alone! This particular variety is something of an enigma in the plant world, with very little reliable information available about its characteristics, growing requirements, or even its native status.

What We Know (And Don’t Know) About Kingdevil

Here’s the honest truth: detailed information about Hieracium praealtum var. praealtum is surprisingly scarce. While the genus Hieracium includes many species commonly known as hawkweeds, this specific variety lacks the comprehensive documentation you’d typically find for garden-worthy plants. The limited available data leaves many important questions unanswered:

  • Native range and geographical distribution
  • Growth habits and mature size
  • Preferred growing conditions
  • Invasive or noxious status
  • Wildlife and pollinator benefits
  • USDA hardiness zones

A Word of Caution

When a plant’s information is this limited, it’s usually a red flag for gardeners. Many Hieracium species are known to be aggressive spreaders or even invasive in certain regions. Without clear documentation about this variety’s behavior, native status, or ecological impact, we can’t recommend planting it in your garden.

Better Native Alternatives to Consider

Instead of taking a gamble on kingdevil, why not choose well-documented native plants that will definitely benefit your local ecosystem? Here are some fantastic alternatives that offer similar yellow flower displays:

  • Native sunflowers (Helianthus species)
  • Black-eyed Susan (Rudbeckia species)
  • Goldenrod (Solidago species)
  • Native asters for late-season color

These plants come with the added benefits of supporting local wildlife, having well-understood growing requirements, and being readily available from reputable native plant nurseries.

The Bottom Line

While the name kingdevil might sound intriguing, the lack of reliable information about Hieracium praealtum var. praealtum makes it a poor choice for responsible gardeners. When in doubt, stick with well-documented native species that you know will thrive in your garden while supporting local ecosystems.

If you’re absolutely determined to learn more about this mysterious plant, consult with your local botanical garden, native plant society, or cooperative extension office. They may have regional knowledge that isn’t widely available online.
