Anatomy of Rose Flower
In many ways, the rose flower is different from that of a standard bloom/flower. The rose flower possesses several ovaries as opposed to the single one of standard blooms. Ovaries are positioned in a cup-like structure called hypanthium. Leaves of the rose plants are borne alternately on stems. These 5-15 cm leaves possess a serrate margin. The petals of rose flowers are typically five in number. However, the hybrid ones have a greater number of petals. With the male and female reproductive parts present in the same flower, it is amongst the perfect flowers.
Sepals and Petals: The sepals and petals are actually the modified leaves of rose flowers. The protective leaves which wrap the buds of rose flowers are known as sepals. As development of the flower takes place, petals begin to unfurl. This process leads to sepals turning backwards. The color and fragrance of petals help in attracting pollinating insects.
Stamens: The stamen is formed of male reproductive parts. Filaments which constitute the stamen have anthers at their tips. Pollen grains are present inside these anthers. Pollen grains of rose flowers are yellow in color.
Pistils: Female reproductive part of the flower is known as pistil. A long stalk (style) and stigma that is present at the tip are parts of pistils. The stigma is characterized by sticky parts where pollen grains get collected. The style is a hollow tube and ovaries are present at its bottom.
Hypanthium: The bulbous and green colored basal part of rose flower is known as hypanthium. This part of the flower is formed by the fusion of petals, sepals and stamens. A flat disk shaped structure present on top of hypanthium is the base of stamen.

If you are an avid gardener, you know that there are many beneficial insects as well as those that are Rose bush pests. Unfortunately, those that do harm get our attention more readily You must resist the urge to grab a bottle of mega-insect-killer and treat the pests individually, rather than with a scorched earth policy.
Insects are a part of the natural world. As gardeners in general and Rose gardeners in particular, we need to realize that while we can try to control rose bush pests in our gardens, we cannot, nor should we want to, eliminate all insects. Scientists estimate that there are 200 million insects for every human on earth. And all of these insects have a place in the natural cycle, they either eat or are eaten by something, pollinate or otherwise have a symbiotic relationship with other plants or animals, and yes, they sometimes eat what we want them not to.

Japanese beetles are a major rose bush pest which have an approximately six week window in July and early August where they are the most destructive. For ways of controlling them, visit our Japanese Beetles web page.
Aphids are tiny greenish to brownish critters that like to suck the life blood out of plants. Fortunately they are easy to see and control by rinsing them off, spraying them with insecticidal soap or controlling them with lady bugs or lacewings.
Cane Borers are the larvae of other insects that like to lay their eggs on the cut end of a rose stem. The borers then eat their way down the stem. Prevention is the easiest way to deter them. Simply coat the freshly cut stem  end when you do your pruning with white glue, fingernail polish, wax, tree wound paint, or anything that will coat the end and make it hard for the insect to lay eggs.
Spider mites are opportunistic pests that thrive in hot, dry conditions. They can be controlled by keeping your Roses watered well in dry periods. Neem oil is an organic pesticide that work  well against spider mites as well as most of the other pests mentioned herein.
Scale sucks. I mean really, they suck the vital juices out of your roses just like aphids. They usually appear on the stems and look like tiny brown bumps. Fortunately they are easily removed with your fingernail. They may also be treated with dormant or agricultural oil as well as insecticidal soaps.
