In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are often different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. The state of having bracts is referred to as bracteate or bracteolate, and conversely the state of lacking them is referred to as ebracteate and ebracteolate, without bracts.
Floriculture, or flower farming, is a discipline of horticulture concerned with the cultivation of flowering and ornamental plants for gardens and for floristry, comprising the floral industry. The development, via plant breeding, of new varieties is a major occupation of floriculturists.
Euphorbia heterophylla, also known under the common names of (Mexican) fireplant, painted euphorbia, Japanese poinsettia, desert poinsettia, wild poinsettia, fire on the mountain, paintedleaf, painted spurge, milkweed, and kaliko plant, is a plant belonging to the Euphorbiaceae or spurge family.
Euphorbia amygdaloides, the wood spurge, is a species of flowering plant in the family Euphorbiaceae, native to woodland locations in Europe, Turkey and the Caucasus. It is a bushy evergreen perennial, growing to a height of 80 cm (31 in), with dark green slightly hairy leaves about 6 cm (2 in) long. The complex green-yellow inflorescence (cyathium), typical of Euphorbia, appears in late spring and early summer.
Chamaesyce is a genus of plants in the family Euphorbiaceae. Recent phylogenetic studies have shown that Chamaesyce is deeply nested within the broader Euphorbia. Specifically, Chamaesyce is very closely related to plants like Euphorbia pulcherrima, the popular poinsettia. Currently, all species have now been reclassified as species of Euphorbia. Specifically, this group now belongs to Euphorbia subgenus Chamaesyce section Anisophyllum. Taxonomically speaking, Chamaesyce is considered a synonym of Euphorbia.
Euphorbia corollata is an herbaceous perennial plant in the Euphorbiaceae family that is native to North America. A common name for the species is flowering spurge. It has a milky sap that can cause skin and eye irritation in some people. It grows up to 1 m (3 ft) tall, with smooth stems and light green leaves arranged alternately or in whorls. Leaves are about 10 mm wide and 75 mm (3 in) long. Each stem terminates in a panicle 20 to 25 mm across. Flowers are about 6 mm across and consist of one pistillate and several staminate flowers surrounded by five white bracts - not petals but formed from the involucre at the base of the flowers. Flowering spurge blooms from June to September.
The Euphorbiaceae, the spurge family, is a large family of flowering plants. In common English, they are sometimes called euphorbias, which is also the name of a genus in the family. Most spurges such as Euphorbia paralias are herbs, but some, especially in the tropics, are shrubs or trees, such as Hevea brasiliensis. Some, such as Euphorbia canariensis, are succulent and resemble cacti because of convergent evolution. This family occurs mainly in the tropics, with the majority of the species in the Indo-Malayan region and tropical America a strong second. A large variety occurs in tropical Africa, but they are not as abundant or varied as in the two other tropical regions. However, Euphorbiaceae also has many species in nontropical areas such as the Mediterranean Basin, the Middle East, South Africa, and the southern United States.
Euphorbia celastroides, previously also known as Chamaesyce celastroides, named 'akoko by the Hawaiians, is a species of spurge closely related to the poinsettia. This species develops into a round-shape shrub. This species is endemic to the Hawaiian Islands.

Euphorbia cyathophora, known by various names including dwarf poinsettia, fire-on-the-mountain, and paintedleaf, is native to North and South America and naturalized elsewhere. They belong to the Cyathium type of inflorescence. Here, the inflorescence axis is convex in shape.
The 2012 San Diego County Credit Union Poinsettia Bowl is a post-season American college football bowl game held on December 20, 2012 at Qualcomm Stadium in San Diego, California in the United States. The eighth edition of the Poinsettia Bowl began at 5:00 p.m. PST and aired on ESPN. It featured the Mountain West Conference co-champion San Diego State Aztecs against the BYU Cougars, and was the final game of the 2012 NCAA Division I FBS football season for both teams. The Cougars accepted their invitation after earning a 6–4 record in their first ten games of the season, while the Aztecs accepted their invitation after finishing with a 9-3 record in their season
Euphorbia punicea is a species of euphorb commonly known as Jamaican poinsettia. It was first described by Olof Peter Swartz in his Nova genera et species plantarum seu prodromus. It grows as a bush or tree three to five meters (10–16 ft) tall, and sometimes much taller. The false flower is in fact a cyathium surrounded by large, colorful bracts.
Polemovirus is a genus of viruses. Commercial cultivars of euphorbia pulcherrima serve as natural hosts. There is only one species in this genus: the type species Poinsettia latent virus.
