Flowering bulbs can be planted out as long as the ground remains unfrozen. Those who put crocuses, narcissuses, tulips, etc. in the garden bed ensure that the blooming season will begin early in the year and that the garden will sport color long before the trees and shrubs start to bud. Whether using an assortment of colors or a strict palette, imagination has no limit in the variety available. Also, when bulbs are skillfully combined with shrubs, garden enjoyment is a sure thing from the get go.
