Invasive Plant Profile: Chelidonium majus, Celandine, Greater Celandine

Revised 2015-02-23: This was one of my earliest blog posts, first published in June 2006. I've overhauled it to 1) meet my current technical standards, and 2) improve the content based on the latest available information.


Chelidonium majus, Celandine or Greater Celandine, is a biennial (blooming the second year) herbaceous plant in the Papaveraceae, the Poppy family. It is native to Eurasia. It's the only species in the genus.

It's invasive outside its native range, and widespread across eastern North America. It emerges early in the Spring, before our native wildflowers emerge, and grows quickly to about 2 feet. That's one of the clues to identification. It's also one of the reasons why it's so disruptive. The rapid early growth crowds and shades out native Spring ephemerals.

An Elegy for Biophilia

I was moved to write this by a short missive from Reverend Billy:
When I go to pray, which is sometimes difficult being so without any god, I think of that time in my life, because the natural world was overwhelming the god that my family insisted was all-powerful and all-knowing. Creation was overwhelming the Creator and it came in the form of undulating prairie grasses.

I was raised in temperate and tropical suburbia. Even in those landscapes, the woods in the backyard, or the palmetto swamp at the end of the road or the canal, drew me to them. They were my expanse. Yet, compared to what existed before the forests were razed and the swamps drained, the landscapes of my childhood were impoverished.

The shifting baseline degrades further. More than half the world now lives in cities, with less ready access to nature than ever before in the history of our species. Biodiversity is an environmental justice issue.

I've chosen to live my adult live in a city. Even here, those childhood experiences guide me. I garden because it connects me to nature, it nourishes me. The beauty I invite is not of my making, but larger, deeper, and older than I can comprehend.

I believe it everyone's right to have that connection for themselves. Not only a right, but necessary. Not only for our own health, but to have some hope for the future health of our planet.

That hope, however impoverished, is what keeps me going.

Pollinator Gardens, for Schools and Others

I got a query from a reader:
I’m working on a school garden project and we’d like to develop a pollinator garden in several raised beds. Can you recommend some native plants that we should have in our garden? Ideally we’d like to have some perennials and maybe a few anchor bushes. Are there any flowers that we might be able to start inside this spring then transplant? Also, because the students will be observing the pollinators, butterfly attracting plants are preferable to the teachers.
Whole books have been written on this topic, but here are some quick thoughts and references for further research.

World Wetlands Day

Not only is it Imbolc, aka Groundhog Day (Flatbush Fluffy did NOT see his shadow today. You're welcome.), it's also World Wetlands Day. After seeing some of the photos shared by others on Twitter, I thought I would share my Flickr photo albums of some memorable wetlands I've had the privilege of visiting.


Cattus Island Park, Toms River, Ocean County, New Jersey


Cranberry Bog Preserve, Riverhead, Suffolk County, New York


The Hudson River, Riparius, Adirondacks, New York
