Two roses growing from one stem

Roses are long, tall "shrubs" with stems of different sizes and shapes, but all roses have prickly thorns covering the stems. (Unless they were modified through genetics, or through cross breeding.) A wild rose's flower has around 5 petals, while a cultivated rose has around double that of a wild rose. A rose's size can range from 0.5 inches to (In a hybrid) 7 inches. [5]

Life Cycle

First, a rose blooms fully, and spreads pollen to other roses. But a rose's pole is heavy, so it needs to be carried by insects.[6] Then inside it's hip (the fruit of the rose) seeds develop. Those seeds will be spread by humans, animals, and nature. Once planted, they will absorb nutrients, and will begin to sprout in about 8-12 weeks. They thrive in warm weather, and in summer, or spring. But in fall and winter, they turn dormant, their leaves change to red, yellow, or brown, and their stalks become weak and wobbly. [7]

Ecology

Description

Roses are most commonly native to the Northern Hemisphere, including areas like: North America, Europe, Asia, and the Middle East. No roses are native to the southern hemisphere. Nearly all species arable to tolerate hot summers, and cold temperature down to -15c. Roses also have thorns along their stems to protect themselves from predators that try to destroy or eat the flower, before it has produced any seeds for another generation of roses. [8]

Growth and Development

Once a new hybrid rose has been chosen, it is propagated asexually with T-budding of the hybrid rose onto a vigorous rootstock. (The most common method) Asexual propagation is used because the rootstock tends to be more winter hardy, (Strong against cold temperatures) and more disease resistant than the hybrid rose. Also, the newly propagated rose will receive all of the original hybrid rose's traits, along with the new ones it developed. In contrast, any seed taken from progeny will segregate and have charectaristics that are different from the original hybrid rose. Rootstock plants for grafting can be propogated from a seed, but are most often clonally propagated using hardwood or softwood cuttings. In areas with cold winters, hardwood cuttings are taken in late fall or early winter. In milder climates, hardwood cuttings are taken in the fall. Softwood cuttings can be taken anywhere from early spring to late summer. The timing depends on the new growth becoming partially mature. Different rootstock plants are used depending on the utility of the hybrid rose. [9]
