Lesser celandine/fig buttercup/ficaria verna

dickf2,

Are there any settings where you'd just let it run or does it jump over walkways and such.

At the garden here, we've got a number of bare area at the moment and this is coming up in one of them. I'm reading about it's invasive habit and yet the yellow blossoms are out right now and the dark green leaves have already covered a small portion of this bare space.

The area where it is currently is actually better for it as I didn't have to plant pachy or ivy as a ground cover BUT will it stay where it is????

We have a large, oval of grass nearby with not even one dandelion, maybe 25 yards, is it at risk?

Best Regards,

editted to "shout out" to Ron - something I just recently learned how to do

@rcarter31:

I apologize for the very long delay in responding.

In the interim, I received a communique from dave. As you may have surmised  from the latest version of my user name. Though this is no excuse. 

To answer your question:  it runs and jumps effortlessly.  And swims.  Like tjohn, I also liked it, when I first saw it many years ago. In Washington Park.  But 

Ecological Threat
Fig buttercup’s greatest threat is to native spring-flowering or “ephemeral” plants. It emerges in the winter in advance of most native species, giving it a great competitive advantage. Once established, it spreads rapidly, forming a solid green blanket across the ground through which native plants are unable to penetrate.

I lifted this ^^ from https://www.nps.gov/plants/alien/pubs/midatlantic/five.htm

If (IF) you didn't eradicate it (back in 2012), how did it go?

And thank you for your Julia Child rec -  excellent garden performance. 

It is no longer an invasive species.  It has successfully invaded and is here to stay.

the only 'good' thing is that it completely is gone by end of May.

Maplewood's most popular alien perennial. Exponentially spreading. The window of opportunity for control is short, and it is NOW - right now - today and tomorrow. Meticulous mechanical removal for small spots; glyphosate otherwise (concentration and contraindications important - details at National Park Service's invasive plant site). Vic is requested to issue a communique on this matter as soon as possible.

I sprayed with recommended dosage and had only limited result I've not killed my entire lawn that we had scrraped and reseeded last fall.  (We used a rototill and it dispersed the left-over tiny seeds...) 

   HELL. 

Dig them up before the flowers become new seeds!!!!

WEll, they spread and continue to suck the life out of whatever is trying to grow, so...

@shanabana: I'm sorry. I know, firsthand, that fighting w/one's lawn is not fun. I've tried, as much as possible, to shun herbicides and the like. But I did have full success  w/ spot Rx of a few tiny islands last spring.

I will presume timing of application was right. Did you give enough time for Rx full effect to take place Before your assessment (of only limited results)? Also, keep in mind the cautions about manual removal mentioned in the monograph. Don't forget residual bulblets.
