Lilium lancifolium seems much larger and goes for full sun. The leaves on this are more delicate, maybe 1/4" across x 2-3" long and the stem staggers side to side at each leaf juncture (a crooked line). The little beady things are about the size of maybe a quilting pin head. Could this be a different lilium type....any guesses out there?

Sorbus aucuparia - a woody weed in this area, as we are seeing in these pictures.

Melissa.... you could have spicata there, I wouldn't know that one personally as I've not grown it, I believe it's considered invasive, but in your large garden that may not be a problem.... the muscari type is less vigorous and clump forming, which also means, as I have found, it's rather slow to establish.... I've grown it before at the base of a steep bank, and reasonably well too where they flowered, but in this garden here not so good, so it's probably my fault.... I grow 'Big Blue' and 'Ingwersens'... and 'Big Blue' is at least showing a bit more life, but both refuse to flower for me... I keep saying.. maybe next year...! I must have at least 20 plants along a border, as I made divisions last year.... ...I think they're quite hardy, as I first became aware of them from a photo of a garden in New York City, some landscaping in a public park there or somesuch, and I thought how nice they looked... ...I'm glad you are happy with your plants, they are at least blooming...

I agree with both peren.all's IDs and the comment that they are both aggessive spreaders in a garden that are difficult to remove once established. I have the grass (variegated ribbon grass is the common name) in a pot where it overwinters well and hasn't escaped, but I wouldn't want either loose in my garden.
