I don't know that Allium, but would like an introduction, please.
Sorry Ricki, It's Allium unifolium . It can be a real pest . I feel guilty because I planted some in my mother's garden . She has heavy clay , They love it and are so thick... like grass . She always pulling them out before they bloom!
I don't think I have that one, but in my gardening youth, I bought a bag of white, yellow and pink allium bulbs and planted. These days, years later, they are all over the place. I don't think I could pull them all out if I tried! Live and learn, huh?
I did a stupid thing , not in my G.Y. , but last year. I was digging out a mass of Muscari from an area. I lazily throw them into another area I had been digging over …and forgot to clear them away ! Now I have a new mass of muscari .
