Located between the two Trial Garden beds, the Bulb Garden is home to many species of plants that undergo a period of dormancy. The term “bulb” typically refers to a perennial plant that re-appears year after year and gets its name from the underground storage organ that provides nutrient reserves to ensure the survival of the plant. Famous bulbs include tulips and onions, but bulbs are not limited to colder climates. There is a wide variety of tropical and sub-tropical bulbs that grow well in South Florida, including amaryllis, lilies, cannas, and more.
True bulbs, corms, tubers, tuberous roots, and rhizomes are underground storage organs lying dormant over winter. Other plants can have similar morphological adaptations to survive periods of stress using succulent leaves and stems, pseudo-bulbs (orchids), bulb-like caudex roots and caudiciform stems (baobabs, cycads).
