A compact selection of the native rattlesnake master, keeping its yucca-like foliage and globe-shaped flower heads in a tidy 3ft frame that won't flop.

'Prairie Moon' is a compact selection of the North American prairie native Eryngium yuccifolium (rattlesnake master), introduced by Intrinsic Perennial Gardens. It keeps the species' signature silvery-gray, strap-shaped, yucca-like foliage and round, bristly, greenish-white flower heads, but in a much shorter, sturdier form — about 3ft tall rather than the species' typical 4-6ft — so it's far less prone to flopping in the garden.

Like the species, it's a true prairie native that thrives in lean, well-drained soil in full sun and is a magnet for pollinators.

Pros

  • Keeps rattlesnake master's architectural form and pollinator value in a shorter, sturdier package
  • Much less prone to flopping than the straight species
  • Deep taproot makes it extremely drought-tolerant once established
  • Rarely browsed by deer or rabbits

Cons

  • Deep taproot resents transplanting or division once established
  • Sharp, spiny leaf tips and flower bracts make handling uncomfortable
  • Seed-grown plants won't reliably stay as compact as the named selection
Highlights This selection solves the straight species' biggest garden complaint — its tendency to open up and flop at 4-6ft — by staying a sturdy, upright 3ft or so, while keeping every bit of the species' wildlife value and yucca-like good looks.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
