This was here when we bought the house, all along the west wall and part of the shady NW corner. That first year, it bloomed with little star-shaped white flowers that almost looked glittery, but it's now been 5 years since I saw a bloom. Any guesses what it is? Any ideas to get it to bloom again?

(ignore the big dandelion--I didn't have my dandelion popper tool with me when I went out to photograph my daffs and hyacinths!)
