Baby Joe Joe Pye Weed (Eupatorium dubium 'Baby Joe')
yew-pah-TOR-ee-um DOO-bee-um 'Baby Joe'

Deciduous Perennial Upright, Clump-Forming in the Asteraceae Family
A compact Joe Pye Weed (just 2-3ft) with dark, greyed-purple stems and domed mauve-purple blooms from late summer into fall. All the butterfly appeal of the wild species, sized for a smaller garden.

'Baby Joe' (US Plant Patent 20,320) is a compact Joe Pye Weed bred by Hubertus Gerardus Oudshoorn in the Netherlands from unnamed purple-flowered Joe Pye Weed selections, though it's sold throughout the US trade as a selection of the coastal species Eutrochium (Eupatorium) dubium. Dark, greyed-purple stems support large, domed mauve-purple flower clusters from late summer into early fall, on a plant that stays notably shorter (2-3ft) than most other Joe Pye Weed cultivars. It's a reliable draw for butterflies, and its sturdy stems and seedheads add winter interest left standing through the cold months.

Pros

  • Compact (2-3ft) habit fits smaller gardens than most Joe Pye Weeds
  • Dark, greyed-purple stems are an attractive feature on their own
  • Domed mauve-purple blooms draw butterflies, late summer into fall
  • Seedheads and stems add winter interest if left standing

Cons

  • Needs consistently moist soil; poor drought tolerance
  • Slow to emerge in spring, so mark its spot to avoid disturbing the crown
  • Patented selection (USPP20,320) — propagation restrictions apply
  • Road-salt tolerance claimed by one retailer but not independently confirmed
Highlights
  • Dark, greyed-purple stems
  • Compact (2-3ft) Joe Pye Weed selection
  • USPP20,320 patented cultivar

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!
