Invasive bulb in my lawn
Sorry if this seems long-winded, but I'm new here. I have an unknown bulb-root plant infesting my lawn. It is clumps of tall, very thin, round shoots, which comes up early March and grows much taller than the grass - about 6 inches. When I dig deep and pull out the clump there are tons of tiny, tiny bulbs surrounding the larger ones. It doesn't smell like onion (which I thought it might be - it looks like chive). Most clumps don't bloom, but when it does it's a very small white flower hidden in the clump of shoots. I think the previous homeowner planted it, but it spread super-fast, took over part of the yard and killed the grass. It was so bad that last year I had the entire lawn taken out and replaced, but the landscaper simply managed to spread the bulbs around more. My garden center says it's Scilla, but from photos I've seen I don't think it is. Does anyone know what this is and how I can get RID of it? I've pulled up the large clumps but there are hundreds of single strands throughout the rest of the lawn.
