Which liquid (water, fresh lemon juice, 7UP, water dissolved with flower food, bleach, or
vinegar) is best for keeping a rose fresh?
I believe that the solution that will keep the roses fresh the best will be the water
dissolved with the flower food, because it is specifically designed and perfected for that
The liquid used to keep the rose fresh
How long each of the rose will stay fresh
Number of days during which they were tested
6 tall containers
6 long stem roses
Labels - for identifying the solutions
1 cup of water
1 cup of fresh lemon juice
1 cup of 7UP
1 cup of water dissolved with flower food
1 cup of bleach
1 cup of vinegar
1. Gather all materials
2. Trim the roses with the scissors
3. Label each of the jars with the name of 1 of the liquids
4. Pour each liquid into its respective container
5. Set 1 rose in each container
6. Set all in a place where the containers won't be disturbed, and they are exposed to
sunlight for the majority of the day.
7. Observe the roses every day for a week
8. Record results
9. Repeat steps 1-8 at least 2x more
What is a rose?
A rose is a woody perennial of the genus Rosa, within the family Rosaceae, with over
100 species. They form a group of plants that can be erect shrubs, climbing or trailing with
stems that are often armed with sharp thorns. Flowers vary in size and shape and are usually
large and showy, in colors ranging from white through yellows and reds. Most species are
native to Asia, with smaller numbers native to Europe, North America, and northwest Africa.
Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Rose
plants range in size from compact, miniature roses, to climbers that can reach 7 meters in
height. Different species hybridize easily, and this has been used in the development of the
wide range of garden roses.
What is a Garden Rose?
Not all roses are garden roses. The ones that I will be using in my experiment are long
stem, pre-cut, garden roses. The difference being that garden roses are usually hybrid. They are
one of the most popular and widely cultivated groups of flowering plants, especially in
temperate climates. Numerous cultivars have been produced, especially over the last two
centuries, though roses have been known in the garden for millennia beforehand. Records exist
of them being grown in Chinese gardens and Greek gardens from at least 500 BC
Why do people grow roses?
Roses are grown mainly as ornamental plants in private or public gardens. Roses can
also be used for medical purposes. The rose hips, or the fruit of the roses can be brewed into
tea that is rich in Vitamin C. Roses can also be used for aesthetic reasons. Their petals are often
therapeutically alleviating if you put them in your bath. Wealthy Ancient Egyptians took rose
baths to symbolize their wealth and prestige, because they could afford them. Bathing in roses
is also said to help your skin. Other than just for decorative uses, the last use for roses is for
perfume. Rose perfumes are made from attar of roses or rose oil, which is a mixture of volatile
essential oils obtained by steam distilling the crushed petals of roses. An associated product is
rose water which is used for cooking, cosmetics, medicine and in religious practices. The
production technique originated in Persia then spread through Arabia and India, and more
recently into Eastern Europe. And since the weight of oil extracted is about one three-
thousandth to one six-thousandth of the weight of the flowers; about two thousand flowers are
required to produce one gram of oil.
How is this helpful to the world/society?
In today’s society, flowers are becoming ever more popular gifts. Among all flowers,
roses are the ones most favored. They come in a rainbow variety of hues. Their main function is
their aesthetic usage, so people want to keep them looking fresh and pretty for a long time. The
best way you can get knowledge of something you know nothing about is through experience.
Yes, it is helpful to get information via the internet and other secondary sources, but who’s to
say they didn’t just make it up? Through this science project, I hope to not only find which liquid
preserves a rose the best, but back it up with proof.
What keeps a rose fresh?
In order to stay fresh, a rose needs water, sunlight, and usually some sort of food that
would normally be provided by the main plant. Water tends to come from a vase or other
container in which you would rest the rose stems in. Sunlight can easily be obtained from
setting the rose outside, or if you wish it to be indoors, near a window. Next, provide a source
of food for your roses. It’s advertised that the flower food that comes with the bouquet of roses
or any other flower is the best. That may or may not be necessarily true, but it is definite that
you need a source of food.
