Spring Beauties

Everyone seems to be aware of our woody invasive plant species like honeysuckle, callery pear, wintercreeper, privet, etc. One thing we’re noticing this year is people gushing over the plant featured here- lesser celandine (Ranunculus ficaria).
Yes, it’s beautiful. It’s one of the first things to come up in spring along floodplains and mesic soils, carpeting the ground in lush green foliage and cheery yellow flowers. You’ll notice at second glance that beneath that lush carpet, there’s NOTHING else growing under or around it. These areas should be loaded with diverse wildflowers- harbinger of spring, bluebells, anemone, phlox, ginger, bloodroot, solomon’s seal, ramps, trout lilies, spring beauty, Dutchman’s breeches, geranium, orchids, twin leaf, trilliums, toothwort, cresses, violets, mayapple, larkspur, hyacinth…just to name a few fan favorites.
Yes, you’ll see pollinators on the flowers. This does not make up for the array of plant species our native insects have coevolved with. One plant does not a balanced diet make. There’s also research showing a reduction in seed set for native ephemerals because pollinators are transferring celandine pollen to them (Masters and Emery, 2015).
There’s much to learn regarding the treatment of celandine and the recovery of once infested areas. Anecdotally, we’ve observed other non-native species and adventive natives trying to muscle out one another near or within areas where celandine is prevalent. We’ve also observed that when an area is cleared of one invasive, another (often a vine) delights in the open space and begins to creep and climb over unoccupied area. Therefore, one must be vigilant of opportunists and other invaders when creating a management plan.
Unfortunately, there’s not much to do aside from herbicide. We currently have crews finishing up foliar applications of systemic herbicide to highly infested areas. There’s a narrow window in which to treat before it’s in full bloom and still able to produce seed. Dense infestations may require more than one treatment because lower leaves aren’t adequately covered and thus don’t effectively transport the herbicide to the root system.
You can voice your concern to land managers and do your part on private land to reduce the spread of this highly aggressive plant.
Do enjoy the pollinators though!
