Summer Bulbs: Nature's Seasonal Showstoppers

Introduction

Summer bulbous plants are among the most attractive ornamental plants used in home gardens, landscapes, parks and commercial flower production. These plants produce underground storage organs such as bulbs, corms, tubers, rhizomes, or tuberous roots that help them survive unfavorable conditions and regenerate each growing season. They are valued for their spectacular flowers, attractive foliage, ease of cultivation and adaptability to different climatic conditions.

Summer-flowering bulbous plants thrive under warm temperatures and bright sunlight, producing vibrant blooms during the hottest months of the year. Popular summer bulbous plants include gladiolus, tuberose, lily, canna, dahlia, caladium, rain lily, elephant ear, and crinum lily.
