Naturalizing simply refers to a way of planting bulbs so they appear as though Mother Nature had done the planting. That is, instead of planting in evenly spaced rows, the bulbs are planted in large drifts, much as you would find plants in nature. One way to achieve this effect is to scatter a handful of bulbs, then plant them where they land. To create a bed that reblooms every year, choose bulbs that are naturally long-lasting and multiply freely, such as daffodils, grape hyacinths, and crocuses.
