first question, ever!
Location: north Italy (Alps)
My mother gave me some plant from her garden about 2 years ago which I then planted in my garden. According to her it's some kind of orchid, but she isn't sure either, and I doubt it too. However it makes briefly some nice flowers.
We had a rather mild/dry winter, this spring the plant/bush is now starting to grow out of control, and I would like to limit its growth: i want to keep the main "bush" and get rid of the seedlings. Where possible I'm considering to pull out the seedlings with roots, but I fear it may grow back again later. Alternatively I am also thinking to pour boiling/salty water far away enough from the main bush (e.g. on the tiles), but I fear that may damage the plant itself, grass and a nearby rose plant. Preferably I would like a pesticide-free method.
1) What kind of plant is it?
2) How can i best remove the new seedlings?
2) What's the best I can do to make it stop overgrow in the future?
The next 2 photos are of April of the previous year, to help with identification and as comparison of how much it has actually grown.
