Snowdrops are inexpensive and multiply with each passing year. They prefer to grow in full sun, but tolerate partial shade. You'll be rewarded with clumps of blooms that increase in number each year. They come in an amazing variety of sizes, scents and shapes, and bloom early, mid- and late season, depending on type. Carefully planned, you can have a splendid, long-lasting show of blooms all spring.
Some tulips multiply, but most fade away after a couple of springs.
Sprinkle a little bonemeal into the bottom of each hole before planting. They put on a grand show in rock gardens, borders and beds, and even under deciduous shrubs and trees. They are great multipliers. Spring bulbs need little maintenance once established. When to Plant Spring-flowering bulbs are planted in fall to give them a period of cold temperature, which stimulates root development.
