Pronunciation/bʌlb/
General Description
In gardening, a bulb refers to a specialised underground storage organ that allows plants to survive adverse conditions and regrow year after year. Bulbs contain all the nutrients and energy the plant needs to sprout, flower, and thrive.
Detailed Description
Bulbs are an essential component of many ornamental gardens, as they produce some of the most beloved flowering plants, such as tulips, daffodils, hyacinths, and lilies. Structurally, bulbs are composed of layers, typically fleshy scales or modified leaves, that store nutrients. At their base, they have a basal plate, from which roots emerge.
Bulbs are typically planted during their dormant phase, often in autumn, to allow them to establish roots before sprouting in spring. They require well-draining soil and should be planted at a depth approximately three times their height. Some bulbs, like snowdrops and crocuses, naturalise well and can spread over time, creating beautiful displays with minimal maintenance.
Bulbs are used for seasonal displays, rockeries, or borders, and they are prized for their ability to return year after year. Maintenance involves deadheading spent flowers to encourage the bulb to store energy for the next growing season and allowing foliage to die back naturally.
Scaling
In home gardens, bulbs are planted manually using bulb planters or trowels. Gardeners often layer different bulb varieties (a technique known as “lasagne planting”) to ensure a continuous display of blooms over the seasons.
In commercial horticulture, bulbs are cultivated on a larger scale for cut flowers or landscaping purposes. Machinery is used to plant and harvest bulbs efficiently, and large-scale bulb farms often specialise in specific varieties for wholesale or export markets.
Etymology
The word “bulb” originates from the Greek “bolbos,” meaning “onion” or “bulbous root.” It entered the English language in the late Middle Ages, initially referring to onion-like plants before becoming a broader term for similar underground storage organs.

Why did the gardener bring a lamp to the flower bed?
Because the bulbs needed a little light to grow!
