A compact, early-blooming, seedless sport of the original Lo & Behold Blue Chip, with bluer flowers and silvery foliage.

Buddleja 'Blue Chip Jr.' (US Plant Patent 26,581) was bred by Dr. Dennis J. Werner at North Carolina State University, selected in 2009 from a cross using the original 'Blue Chip' as the female parent. It is genuinely sterile -- the flowers lack functional anthers and set no viable seed -- so it spreads only by its own dense, mounding growth, never by seeding into the garden or surrounding landscape.

Compared to its parent, 'Blue Chip Jr.' is slightly smaller, blooms noticeably earlier in the season (often beginning in late spring), and carries bluer purple-violet flower spikes above silvery-gray foliage, blooming continuously without deadheading from early summer into fall.

Pros

  • Genuinely sterile -- sets no viable seed, so it will not self-sow
  • Earliest-blooming selection in the Lo & Behold series
  • Fragrant flowers that rebloom continuously without deadheading
  • Compact, dense habit; deer resistant and drought tolerant once established

Cons

  • Flowers only on new growth, so hard spring pruning is still the best practice for a full, tidy shape
  • Can develop spider mites during extended drought
  • Still a true Buddleja hybrid -- not reliably hardy much below Zone 5
Highlights Fragrant Flower Continuous Bloom or Rebloomer Long Blooming Deadheading Not Necessary Drought Tolerant

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.

About Ordering From The Plant Club

To secure the best prices for club members and make sure we know the current plants available from each nursery, we take orders only a couple of times a month.

Shoot us an email at help@northshoreplantclub.com, and we'll be happy to talk about plants or let you know when it's time to buy them!


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!
