Year-After-Year Flowers
Some flowers don’t have to be planted every year. You plant them just once and leave them in the ground. From then on, they bloom each year. Tulips, for example, have beautiful cup-shaped flowers that bloom each year. Lilies have blade-shaped petals and showy stamens.
Plants that bloom every year are called perennials. Many perennials grow from bulbs or from bulb-like parts called corms. Bulbs are underground buds. They are made up of a small stem covered with thick, fleshy leaves. Onions, tulips, and lilies grow from bulbs. Corms are very similar to bulbs, but their leaves are smaller and thinner. Crocuses and gladioli grow from corms.
Most bulbs and corms should be planted in the autumn. But the package they come in will tell you the best time to plant them.
Many perennials need protection during winter. The package your seeds or bulbs come in, or a gardening book, will tell you what to do for each kind.
