    This is the only allium that is really happy in my shady garden. In fact, it doesn't like full sun, unlike most, if not all alliums. It even self-sets in spots that get hardly any sun at all! Beautiful in all stages, even with seed pods. The leaves are pretty too, another bonus, and it blooms the longest of all alliums I know..
