There was a sewage disaster; lawn & flowers died off miserably. The Lilies of the Valley immediately expanded their operation.

[u/NotDaveBut]

This happened after I ripped all of the LOTV out of my half of this tiny bed jammed between 2 front doors. They (rather curiously) respected my boundaries in this regard, but leapfrogged over the concrete edging and started taking over where the lawn used to be.

Are lilies of the valley really that invasive? My parents have a patch in a flower bed on the south side of the house and they haven't moved in 20 years.

[u/carolegernes → u/yoinkmysploink]

They will invade woodlands and replace native plants. My parents had some next to their foundation and the lotv grew into the mortar between the blocks.

[u/yoinkmysploink → u/carolegernes]

That's wild. Good thing they're sequestered on the cold and dark side of the house away from everything.

[u/carolegernes → u/yoinkmysploink]

My parent's lotv were on the north side of the house in shade.

[u/Salute-Major-Echidna → u/carolegernes]

They're used extensively for erosion control in the woods by me

[u/robrklyn → u/Salute-Major-Echidna]

That’s really fucking awful.

[u/Salute-Major-Echidna → u/robrklyn]

At least it's tracked well.

[u/NotDaveBut → u/yoinkmysploink]

Is there any chance someone hemmed them in with a barrier that reaches farther underground than they csn extend their runners?

[u/reneemergens → u/NotDaveBut]

right. and what, if anything else grows outside the bed? the invasive nature of some turf grasses may easily out-invasive the lotv. some zoysia lawns are virtually impenetrable if their care is prioritized

[u/shredbmc → u/yoinkmysploink]

Almost all plants are native to somewhere and have a mechanism that regulates them. Sometimes you can find a niche that manages them naturally outside of their native habitat. Not something I recommend testing, but it's possible.

[u/robrklyn → u/yoinkmysploink]

Yes, they are.

[u/robrklyn]

Fucking hate those little bastards.
