Bluefly Honeysuckle: A Hidden Gem for Wildlife-Friendly Gardens

If you’re looking for a native shrub that’s both beautiful and beneficial to wildlife, let me introduce you to the bluefly honeysuckle (Lonicera caerulea var. cauriana). This charming perennial shrub might not be the flashiest plant in the garden center, but it’s definitely one of the most valuable additions you can make to a wildlife-friendly landscape.

What Makes Bluefly Honeysuckle Special?

Bluefly honeysuckle is a true North American native, calling the western regions of the continent home. This multi-stemmed woody shrub typically grows to a manageable 13-16 feet in height, though it often stays much smaller in garden settings. Don’t let the honeysuckle name fool you into thinking this is an invasive vine – this variety is a well-behaved shrub that plays nicely with other native plants.

Also known by its scientific name Lonicera caerulea var. cauriana (and sometimes listed as Lonicera cauriana Fernald), this perennial shrub brings year-round interest to your garden with its attractive form and seasonal changes.

Where Does It Naturally Grow?

This hardy native has quite an impressive range across western North America. You’ll find bluefly honeysuckle growing naturally in Alberta and British Columbia in Canada, and throughout the western United States including California, Idaho, Montana, Nevada, Oregon, Washington, and Wyoming. Its wide distribution speaks to its adaptability – a great sign for home gardeners!

Garden Appeal and Landscape Role

What really sets bluefly honeysuckle apart is its dual-season beauty. In spring, the shrub produces small, creamy-white to pale yellow tubular flowers that have a subtle, sweet fragrance. These blooms are absolutely beloved by pollinators, making your garden a buzzing hub of activity. Later in the season, the flowers give way to blue-black berries that provide food for birds and other wildlife.

In the landscape, bluefly honeysuckle works wonderfully as:

  • An understory plant in woodland gardens
  • A naturalized shrub in wildlife habitat areas
  • Part of a native plant collection
  • Erosion control on slopes
  • A screening plant for informal borders

Perfect Growing Conditions

One of the best things about bluefly honeysuckle is its easygoing nature. This adaptable shrub thrives in USDA hardiness zones 2-7, making it suitable for a wide range of climates. It’s particularly well-suited to cooler regions and can handle quite a bit of cold.

The plant shows remarkable flexibility when it comes to moisture levels. With a facultative wetland status across its range, it can handle both moist and moderately dry conditions. This means it can work in areas that occasionally flood as well as in more typical garden situations – talk about versatile!

For best results, provide:

  • Partial shade to full sun exposure
  • Well-draining soil that retains some moisture
  • Protection from harsh, drying winds

Planting and Care Tips

Getting bluefly honeysuckle established in your garden is refreshingly straightforward. Plant it in spring or fall when temperatures are moderate and rainfall is more reliable. Dig a hole twice as wide as the root ball but no deeper, and backfill with native soil.

Once established, this native shrub is wonderfully low-maintenance:

  • Water regularly the first year, then only during extended dry periods
  • Apply a 2-3 inch layer of organic mulch around the base
  • Minimal pruning needed – just remove dead or damaged branches
  • No fertilization required in most soils

Wildlife and Pollinator Benefits

Here’s where bluefly honeysuckle really shines! The spring flowers are magnets for native bees, butterflies, and other beneficial insects. The nectar-rich blooms provide crucial early-season food when many other plants haven’t started flowering yet.

The blue-black berries that follow are a feast for birds, including thrushes, waxwings, and other berry-loving species. Small mammals also appreciate the fruit, and the shrub’s branching structure provides nesting sites and shelter for various wildlife.

Is Bluefly Honeysuckle Right for Your Garden?

If you’re creating a native plant garden, establishing wildlife habitat, or simply want a low-maintenance shrub with seasonal interest, bluefly honeysuckle deserves serious consideration. It’s particularly perfect for gardeners in western regions who want to support local ecosystems while creating beautiful, sustainable landscapes.

The plant works especially well in informal, naturalistic settings where its somewhat wild appearance fits right in. It’s not the best choice for formal, highly manicured gardens, but in the right setting, it’s absolutely perfect.

With its native status, wildlife benefits, and easygoing nature, bluefly honeysuckle proves that sometimes the best garden plants are the ones that have been quietly growing in our landscapes all along. Give this underappreciated native a try – both you and your local wildlife will be glad you did!

Lonicera caerulea var. cauriana is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Lonicera caerulea var. cauriana is also known as:

Lonicera cauriana | USDA symbol: LOCA9

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" — matching plants to their ideal growing conditions, so they'll thrive with less care and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection can be if you don't have the right information. While tags on nursery plants list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. You might be surprised to learn that popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. The table below gives insight into the preferred growing conditions of this plant throughout its geographical distribution.
