Bulbs Perennials - Garden Flowers

First let me tell you that all flower bulbs are designed by nature to be perennials. That's the real point of a bulb, they are like food storage organs for dormant plants.

By definition a bulb is any kind of plant that stores the complete life cycle on an underground storage structure. The primary objective of these bulbs (underground storage structures) is to retain sufficient nutrient reserves that will permit the survival of the plant. With this system, the plant has the ability to survive and restart the life cycle year after year. The majority of information sources tell us that the flower bulbs are perennial. We can't think of any good examples of an annual bulb, perhaps climates that lend to these bulbs blooming just once and then drying down completely. Because of that, the majority of the expert opinions are that all bulbs are classified as perennials, since they have the ability and structure for that. There are exceptions of course, some of them are not able to fulfill this life cycle because of climates and other factors.

Many bulbs, particularly summer flowering bulbs, is not winter hardy in colder regions where they are planted by gardeners. If they are not dug up, they die. They are treated by gardeners in these regions as annuals. However, in a warmer climate or during a mild winter, they would be perennials.

One good example is the Daffodils, that come from Holland, but you can find them all over the world where they can sustain life they don't reproduce as normal plants, but they live, produce and go dormant in extreme weather, only to revive in more temperate times, they are an extremely hardy plant.
