Three-inch golden yellow flower heads over mounds of finger- shaped green leaves. Essential food source for the monarch butterfly larvae.
‘Hello Yellow’ is a golden-yellow-flowered selection of butterfly weed (Asclepias tuberosa), grown from open-pollinated seed for a more uniform flower color than the mixed orange-to-red tones typical of the species. Clusters of flat-topped, nectar-rich flower heads open atop upright, clump-forming stems clad in narrow, lance-shaped green leaves from summer into early fall. Like the species, it develops a deep taproot that stores water and nutrients, making it slow to establish but long-lived and highly drought-tolerant once settled in. Deadheading spent flower clusters often triggers a second flush of bloom about a month later. It is a key larval host and nectar source for Monarch butterflies.

Pros

  • Reliable golden-yellow color, more uniform than the mixed-color species
  • Deadheading can trigger a repeat bloom later in the season
  • Deer- and rabbit-resistant, and highly drought-tolerant once established
  • Key larval host and nectar source for Monarch butterflies and other pollinators

Cons

  • Slow to establish; may take 2-3 years to bloom reliably
  • Deep taproot makes it difficult to transplant once established
  • Sap can irritate skin; wear gloves when handling or cutting stems
Highlights The species Asclepias tuberosa was named the Perennial Plant Association's 2017 Perennial Plant of the Year. ‘Hello Yellow’ brings that same tough, pollinator-friendly performance in a clear golden-yellow color, uncommon among butterfly weed selections that typically range orange to red.

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!
