In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy.
Erythronium is a genus of Eurasian and North American plants in the lily family, most closely related to tulips. The name Erythronium derives from Ancient Greek ἐρυθρός (eruthrós) "red" in Greek, referring to the red flowers of E. dens-canis.
The lily family, Liliaceae, consists of about 15 genera and about 705 known species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of petaloid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in other orders. Consequently, many sources and descriptions labelled "Liliaceae" deal with the broader sense of the family.
Hippeastrum is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers.
Crinum is a genus of about 180 species of perennial plants that have large showy flowers on leafless stems, and develop from bulbs. They are found in seasonally moist areas, including marshes, swamps, depressions and along the sides of streams and lakes in tropical and subtropical areas worldwide.
Camassia is a genus of plants in the asparagus family native to Canada and the United States. Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth.

The Chicago Botanic Garden is a 385-acre (156 ha) living plant museum situated on nine islands in the Cook County Forest Preserves. It features 27 display gardens in four natural habitats: McDonald Woods, Dixon Prairie, Skokie River Corridor, and Lakes and Shores. The address for the garden is 1000 Lake Cook Road, Glencoe, Illinois. The garden is open every day of the year. Admission is free, but parking is $30 per car.
In botany, succulent plants, also known as succulents, are plants that have some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. The word "succulent" comes from the Latin word sucus, meaning juice, or sap. Succulent plants may store water in various structures, such as leaves and stems. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In horticultural use, the term "succulent" is sometimes used in a way which excludes plants that botanists would regard as succulents, such as cacti. Succulents are often grown as ornamental plants because of their striking and unusual appearance.
Tulips (Tulipa) form a genus of spring-blooming perennial herbaceous bulbiferous geophytes. The flowers are usually large, showy and brightly coloured, generally red, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the Liliaceae (lily) family, along with 14 other genera, where it is most closely related to Amana, Erythronium and Gagea in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble. Tulips originally were found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalised and cultivated. In their natural state they are adapted to steppes and mountainous areas with temperate climates. Flowering in the spring, they become dormant in the summer once the flowers and leaves die back, emerging above ground as a shoot from the underground bulb in early spring.
Arisaema candidissimum is a species of flowering plant in the arum family (Araceae), originating in western China. Various English names have been given to the species, including striped cobra lily and Chinese jack-in-the-pulpit. The Chinese name is 白苞南星.
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England. His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture. He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including Daphne, Lewisia, and Helleborus. His work has been recognized by the British Royal Horticultural Society and the International Bulb Society.
