Perennial bulbs
include spring-flowering favorites like crocus, daffodils, hyacinth and tulips. There are several bulb species used for gardens including true bulbs, tubers, tuberous roots, rhizomes, corms and enlarged hypocotyls. Perennial bulbs can be planted on their own in flower beds for a stunning effect, or they can be mixed in with other perennials to help extend the blooming season of your garden. Also, by mixing perennial bulbs in among other plants will help hide the yellowing foliage of bulbs after they are finished blooming. (Remember - not all your perennial plants and bulbs will bloom at the same time.)
