And you often get self sown seedlings all over the place too.
Interesting point about leaving the seed heads. On some bulbs, Tulips, Narcissus for example, removing the dead flower helps the bulb keep its strength for next season, but with Alliums, it is already too late. They flower after the leaves have done their job and begun to die. In fact the flower stem is almost disconnected from the bulb altogether,
