Growing on the edge of my yard I have a small clump of perennial plants that produce small white flowers in late May or early June. The flower itself is white, with six petals, and they are produced at the tips of a small branching flower stalk. The plants they come from has long, narrow, hollow leaves, with a white-ish mid-rib.
It's currently in somewhat of a bad place, close enough to the lawn that it almost gets mowed and right where a roof down-spout empties. I'd like to move it somewhere better, but first I need to know what it is, and where is best for it. Growing in USDA Zone 6.
