The funny thing about planting bulb flowers is there's a chance that you forget where you put them. That was the case with my grape hyacinth after I started watering the radish seeds. Within a week or so, at the the beginning of September, they started coming up. I hadn't watered that area all summer because I thought those flowers were spring bloomers, not fall bloomers, so I figured I could just leave them alone. But they came up anyway, after I started watering that area, and since then they've become garden roommates more or less.
A couple side notes--first, I've confirmed with a local master gardener that the holes in the leaves aren't worth worrying over this late in the season. Second, because I planted the seeds so late in the season, I've been told that it will take a lot longer for them to be ready to eat than what is specified on the packet. I can't wait!
