Indigo Spires commands attention in the garden with its impressive, indigo-blue flower spikes and robust, shrub-like growth habit.
Indigo Spires is a robust hybrid false indigo bred for a dense, rounded, shrub-like habit and an unusually long bloom season. In late spring, dozens of upright spikes rise well above the blue-green foliage, each packed with deep violet-purple pea-flowers accented by a bright yellow keel. Where many false indigos bloom once and finish, this selection sends up secondary flower spikes through early summer, stretching the display considerably. Foliage stays attractive from spring through fall, and the plant's deep taproot makes it extremely long-lived and drought-tolerant once established.

Pros

  • Unusually long bloom season thanks to secondary flower spikes
  • Dense, rounded, shrub-like habit gives structure without pruning
  • Extremely long-lived and drought-tolerant once established
  • Deer resistant and attracts bees and butterflies

Cons

  • Slow to establish, taking a couple of seasons to reach full size
  • Deep taproot makes it resent transplanting once settled
  • May need staking if grown in too much shade
Highlights A dense, rounded mound of blue-green foliage topped with a dozen or more spikes of deep violet-purple, yellow-keeled flowers, with secondary spikes that keep the show going well past the usual false indigo bloom window.

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!
