Monarch® Glass Slippers Butterfly Bush (Buddleja 'Glass Slippers') is a compact, seedless hybrid bred by Hans A. Hansen for Walters Gardens and patented in 2017 (US PP27,832). Selected from open-pollinated seedlings at a Zeeland, Michigan nursery in 2011, it produces icy, fragrant periwinkle-blue flower spikes from early summer into fall. Because its flowers lack functional anthers and pollen, it sets little to no seed, avoiding the self-seeding problems of older butterfly bush varieties. Mature plants form a dense, rounded mound, generally wider than tall, that fits well into mixed borders and smaller gardens.
Pros
Fragrant periwinkle-blue flower spikes from early summer into fall
Seedless and non-invasive, unlike older butterfly bush varieties
Compact, well-behaved mounded habit
Drought tolerant once established
Deer resistant and tolerant of urban pollution and salt
Cons
Needs plenty of sun to bloom well and stay compact
Benefits from an annual hard pruning in late winter
Wider than it is tall, so it needs room to spread
Can suffer winter dieback at the colder end of its hardiness range

We try very hard to source exactly what you’d like, but sometimes growers run out of plants! While this variety is a great deal at the price shown, we know that it has limited availability. If you want the plant even if it might be more expensive, or in a different size or quantity -- after you place your order, just send us a quick note at help@northshoreplantclub.com. Then, we’ll try to get you some version of this from one of our growers. And if we can’t get it from anywhere, of course, we’ll send a refund!
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!
