A Chicago Botanic Garden introduction with extra-long violet-blue flower spikes and a tidy, vase-shaped habit that holds up without staking.
Baptisia 'Midnight Prairieblues' is an interspecific false indigo hybrid developed by Dr. Jim Ault at the Chicago Botanic Garden as part of the Prairieblues series. Its deep violet-blue, pea-like flowers open along exceptionally long, upright racemes that can reach nearly two feet, and a flush of shorter secondary spikes extends the bloom season several weeks beyond most Baptisia cultivars. Blue-green, clover-like foliage forms a dense, vase-shaped clump that holds its shape through the season without staking, then matures into dark seed pods that add winter interest. Like other false indigos, it develops a deep taproot and is best sited where it can grow undisturbed for years.

Pros

  • Extra-long flower spikes with a bloom period several weeks longer than most Baptisia
  • Sturdy, vase-shaped habit that resists flopping without staking
  • Deer-resistant and drought-tolerant once established
  • Attracts bees and other pollinators

Cons

  • Deep taproot makes established plants difficult to divide or transplant
  • Slow to reach full size and mature bloom
  • All plant parts are toxic if ingested
Highlights Exceptionally long, deep violet-blue flower spikes extend well beyond the foliage, and a rebloom of shorter secondary spikes keeps the show going longer than most Baptisia. A tidy, upright, vase-shaped clump holds up to summer storms without staking.

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!
