Intensia Red Hot Phlox (Phlox drummondii 'Intensia Red Hot')
flox drum-MON-dee- 'Intensia Red Hot'

Annual in the Polemoniaceae Family

Annual Phlox is a low, mounding wildflower native to Texas and the south-central United States, where it completes its whole life cycle - germinating, blooming, and setting seed - in a single season, often reseeding itself for the following year.

Clusters of five-petaled, tubular flowers cover the plant through the growing season, drawing butterflies and bees. The wild type is typically rose-red, though cultivated seed strains span a much wider color range.

Pros

  • Fast, easy to grow from seed, blooms the same season
  • Long bloom season, from spring planting until frost
  • Attracts butterflies and bees
  • Tolerates heat well once established

Cons

  • An annual - needs replanting or reliable reseeding each year
  • Best bloom and habit come with full sun
  • Can decline in prolonged summer humidity without good air movement

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!
