A rose is a perennial flower shrub or vine of the genus Rosa, within the family Rosaceae, that contains over 100 species and comes in a variety of colours. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, cultivars and hybrids are all widely grown for their beauty and fragrance.

The leaves are alternate and pinnately compound, with sharply toothed oval-shaped leaflets. The plant's fleshy edible fruit is called a rose hip. Rose plants range in size from compact, miniature roses, to climbers that can reach 7 meters in height. Species from different parts of the world easily hybridize, which has given rise to the many types of garden roses.

A poppy is any of a number of colorful flowers, typically with one per stem, belonging to the poppy family. They include a number of attractive wildflower species with colorful flowers found growing singularly or in large groups; many species are also grown in gardens. Those that are grown in gardens include large plants used in a mixed herbaceous border and small plants that are grown in rock or alpine gardens.

The flower color of poppy species include: white, pink, yellow, orange, red, and blue; some have dark center markings. The species that have been cultivated for many years also include many other colors ranging from dark solid colors to soft pastel shades. The center of the flower has a whorl of stamens surrounded by a cup- or bowl-shaped collection of four to six petals. Prior to blooming, the petals are crumpled in bud, and as blooming finishes, the petals often lie flat before falling away.

The pollen of the oriental poppy, Papaver orientale, is dark blue. The pollen of the field poppy or corn poppy (Papaver rhoeas) is dark blue to grey. Bees will use poppies as a pollen source.

Petunia is a trumpet shaped, widely-cultivated genus of flowering plants of South American origin, in the family Solanaceae. The popular flower derived its name from French, which took the word petun 'tobacco' from a Tupi-Guarani language. The species was first sent from South America to Paris in 1823, discovered in South America by the explorer James Tweedie.

Many open-pollinated species are also gaining popularity in the home garden. A wide range of flower colours, sizes, and plant architectures are available including Grandiflora, Spreading, Mulitflora and Milliflora in both the hybrid and open-pollinated species.

The name "Marigold" is derived from "Mary's Gold", and the plant is associated with the Virgin Mary in Christian stories. Tagetes is not to be confused with the genus Calendula, which goes by "marigold" in some areas.

The marigold was regarded as the flower of the dead in pre-Hispanic Mexico, parallel to the lily in Europe, and is still widely used in the Day of the Dead celebrations. The marigold is also widely cultivated in India and Thailand. Vast quantities of marigolds are used in garlands and decoration for weddings, festivals, and religious events.

Marigolds can grow well in almost any sort of well drained soil but are best grown in partly sandy soil with good drainage. Although only hybrid varieties are used for cultivation, a good number of pure plantations are available. It is highly temperature resistant. Most varieties are seasonal and dry out after some good flowering phases.

The sunflower is native to the Americas. The evidence thus far is that it was first domesticated in Mexico, by at least 2600 BC.

To grow well, sunflowers need full sun. They grow best in fertile, moist, well-drained soil with a lot of mulch. What is usually called the flower is actually a head (formally composite flower) of numerous florets (small flowers) crowded together. The outer florets are the sterile ray florets and can be yellow, maroon, orange, or other colors. The florets inside the circular head are called disc florets, which mature into what are traditionally called "sunflower seeds," but are actually the fruit (an achene) of the plant. The inedible husk is the wall of the fruit and the true seed lies within the kernel.
