Answer: Your Allium bulbs were probably recently dug and divided from someone else's garden. Go ahead and replant them now, placing small bulbs 3"- 5" deep and large bulbs 6" - 8" deep in very well-drained, but not too rich soil. Space the bulbs 6" - 12" apart, depending upon size. Your bulbs are probably summer-flowering bulbs (traditionally divided in the spring), but if they don't flower this summer, they'll probably flower next spring.
