wild growth or planned planted

Hello

I moved into new house and found this plant. It seems like a wild growth in my impression but it was planted in rows. just wondering if it might have be brought and planted or just grew from no where.
Also what could be uses of this plant for decor etc(if any) or flaws ( eats vegetation)

Thanks

 

Yellow archangel, now considered a pest plant in this region.

 

that means not good for my garden

 

In this case, you're using the common name because there are so many botanical names? I see Lamium galeobdolon, Galeobdolon luteum, Lamiastrum galeobdolon, Lamium luteum. Well, and another common name: deadnettle.

I see that there is a cultivar that is supposed to be less invasive: Lamium galeobdolon 'Hermans Pride', but that's not this one. It's a popular plant in shady areas because it grows so well. Its flaw is that it spreads easily and smothers other vegetation.

 

Lamium galeobdolon. The common name is "yellow archangel," but the specific epithet means "weasel stench." The plant is neither angelic nor particularly stinky, but it's a nice juxtaposition of meanings.

 

Accepted name is Lamiastrum galeobdolon: http://wbd.etibioinformatics.nl/bis/flora.php?selected=beschrijving&menuentry=soorten&id=3469

 

This plant is quite often found in hanging baskets. It looks nice so people put it in their garden to find out it takes over.
I have it in various areas on my property and I am constantly trying to get rid of it. I would not recommend leaving it in your garden.

 

But see the Plant List and GRIN. The latest molecular phylogenetic analysis finds that L. galeobdolon is "sister" to all other Lamium species. In other words, evolutionarily distinct, but still a Lamium.

 

If it is sister to all other Lamium, then it can be either excluded from or included in the genus, without making any difference to monophyly. So neither Lamium galeobdolon nor Lamiastrum galeobdolon is wrong, it is optional according to preference.

 

The same plant was deliberately planted in my yard as ground cover/decoration. It's popular around many other homes in this area. It's also edible.

I take your point. I had not thought it through.

 

Presumably this would be why you see both still being given, without one having come to dominate.

 

Yep, an awkward decision for flora authors to have to make! There's always the possibility that future studies might clarify the situation, e.g. using species in related genera not analysed in the Taxon paper.
