Orchids Weeds

The Orchid Nobody Wants

Broad-leaved hellebore in bloom.

The following article was first posted to this blog on June 26, 2018. I’m reposting it today because I’ve been receiving a lot of questions about this plant recently, so obviously there is an interest, especially since it appears mysteriously in both forests and gardens.

Orchids are such desirable plants that’s hard to imagine there are any that don’t attract many favorable reviews … but there is indeed one and it’s Epipactis helleborine or broad-leaved helleborine. This widely distributed Eurasian terrestrial orchid long ago made it to the New World where it has spread like wildfire thanks to its very fine wind-borne seeds and is now abundant throughout eastern North America, from Newfoundland to the Great Lakes region and south to Tennessee. It is also locally common in many regions of the West Coast and, to a lesser degree, the Midwest.

Most people don’t realize it’s an orchid, though. They just see a plant they didn’t plant … and want it gone!

The first thing you see are the curiously pleated leaves in the spring that you might confuse with that other accordeon-leaved plant, false hellebore (Veratum spp.), but which is in no way related.

It forms an upright stem from 1 to 2 ½ feet (30 to 80 cm) tall, arching at the tip when it bud, with broad, pointed, parallelly ribbed leaves.

In mid to late July or in August, small green, greenish purple or pinkish flowers, somewhat nodding, form on a one-sided terminal spike. If you look closely, you’ll clearly see its bowl-shaped labellum, proof it’s an orchid.

The colors are variable: just in my own yard, I have mostly green ones, some pinker ones and a few that are quite pretty in purple. The labellum is often a different shade from the pointed tepals.

After the flowers fade, ribbed dangling seed capsules remain green until fall, then turn brown and open.

I find it seems to love mulch and somehow manages to germinate in the most carefully mulched beds, one of the few plants able to do so.

Reigning It In

Yes, you can call this a weed if you want. I don’t. I actually like it. And although it does show up in the shadier parts of my yard (it seems to prefer shade to sun), it’s not exactly a very obtrusive plant, nor does it take over. It just pops up here and there, even in spots totally dominated by tree roots where little else will grow.

It is apparently hard to get rid of. Certainly, pulling, hoeing or digging it just seems to make things worse, as the slightest bit of rhizome remaining will produce a new plant. It’s said to be highly resistant to herbicides too, although I have no proof of this, as I’ve never tried such products.

If you really want to get rid of it, don’t hoe it, but rather cut it back and keep cutting it back each time it resprouts. If it shows up in a lawn, just mow it down. If you constantly cut off its leaves, it won’t be able to carry out photosynthesis and will (eventually) die. You’ll actually find it isn’t very persistant if you treat it that way.

I just leave it be. It’s just not a dominant enough plant to be worth fighting … and it’s pretty enough in its modest way. I suggest learning to like it!

  1. Looks good to me, but I have never seen it in the south.

    While I’ve had it in the past (Michigan Zn 5), not this year for some reason. I did pull a few out last year but I know not all of them. The only thing different this year has been the more than generous rain we’ve received. Maybe they don’t like wet conditions?

  3. It grows in my current garden, but I never had it in my former garden 20 minutes away. I’m with you, I kind of like it and don’t find it to be a problem. There are native plants such as certain goldenrods and Canada anemone that wreak far more havoc in my garden. But now you’ve got me thinking: there are plants in a wild area down the street that I always thought were Veratrum, but now I’m wondering if they’re just very big helleborines. I’d have to go down a very steep slope to investigate.

    I just was on a garden tour today in Falmouth, Maine. Lo and behold, the hostess gardener showed us the helleborine she’d discovered under a tree. Like you, she’d been weeding them out until she realized they were orchids!

  5. I have a couple that pop up reliably every year. Like you, I don’t mind it and just let it be. There are worse weeds to fight than this one.

  6. Yes, we got it here also, at least locally. I notice it only in coastal regions, but have never seen it in the Santa Clara Valley, just a few miles away. Perhaps it dislikes chaparral climates. Some people here insist that it is native. Although not overly common, a few come up in more refined parts of the landscape. I would like them gone, but will not put too much effort into getting rid of them.
