Color Spires Crystal Blue Sage (Salvia nemorosa 'Crystal Blue')
SAL-vee-ah nem-or-OH-sah 'Crystal Blue'

Deciduous Perennial in the Lamiaceae Family
Bountiful mass of unique light sky-blue flower spires over aromatic rugose gray-green foliage.

A Proven Winners Color Spires® selection valued for its unusually cool, pale sky-blue flower spikes — a refreshing departure from the deep violet-blues typical of this species. Compact, upright habit holds up well in beds, borders, and containers.

Pros

  • Pale sky-blue flower spikes, a standout color break in the genus
  • Compact, tidy upright habit
  • Reblooms readily if cut back after the first flush
  • Deer and rabbit resistant; drought tolerant once established

Cons

  • Needs good drainage, especially over winter
  • Benefits from division every 2-3 years to maintain vigor

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.

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!
