Rose: Symbol of Fantasy


Flowers bear the potential to make any person smile by their attractive colour, fragrance and beauty. Rose is one such good example of this. Rose is a perennial plant belonging to the genus Rosa and family Rosaceae. There are about 100 species of rose are known. The species of rose may be erect shrubs, climbing or trailing plants with stem armed with prickles. Flowers are large, showy with a colossal range of colours like red, yellow, orange pink, white and so on. Majority of the species are native to Asia but others also belong to Europe, northwest Africa and North America. Both cultivars as well as hybrid varieties are grown all over the world for their beauty as well as fragrance. The plant may vary in length from compact, miniature plants to the climbers reaching 7 meters. Hybridization can be easily carried out in these plants so a wide variety of garden roses are easily available. The name rose has been derived from a French word while the scientific name Rosa comes from Latin.    (

Rosaceae Roses and Flowers

)

The leaves are arranged alternately on the stem and vary 5-15 cm in length, pinnate and with 5-9 leaflets and basal stipules. The leaflets are provided with serrated margins and armed with prickles on the underside of the stem. The plants are deciduous but some are evergreen also. The flower generally bears five petals but Rosa sericea is an exception with four petals. Each petal is provided with two lobes and are brightly coloured with different shades of colour. Just beneath the petals there are five sepals which are sometimes large enough that they become visible from above and are alternately arranged. Ovary is inferior which means it develops below the petals and sepals. They are good examples of insect pollinated plants. The fruit is a berry-like structure called as rose-hip. Many domestic varieties do not produce rose hip as the petals are so intimately arranged that they do not provide insects a chance to pollinate the flowers. The hips may be red, purple or black in colour. The hips have an outer fleshy layer known as hypanthium which contains 5-60 seeds covered with stiff hairs. Rose hips of Dog Rose, Rugosa Rose are rich sources of vitamin C. the hips are eaten by small birds like waxwings, finches and thrushes which disperse the seeds through their droppings.

The pricles on the rose stem are typically sickle-shaped hooks which are used for hanging over the vegetation while growing over them. Despite the presence of prickles they are frequently browsed by deer. They form the world's best ornamental plants even grown indoors. The flowers are also used in perfumery as well as cut crop production. Some are also used as landscape plants and also have minor medicinal uses. Rose perfume is made from rose oil which is a mixture of essential compounds. Rose oil contains alcohols geraniol and l-citronellol; and rose camphor, an odourless paraffin. ?-Damascenone is an important component of scent. Rose water left after the extraction of rose oil is used in cuisines in Middle East and Asian countries. Rose hips are also used in making jams, jellies, marmalades as they are rich sources of vitamin C. Roses are also used in Chinese system of medicine for curing stomach problems as well as for the investigation of cancerous growth.

Roses are also a source of fantasy for the artists. Roses are at higher risk of getting infected by the fungal diseases like rose black-spot, rose rust, rose powdery mildew, downy mildew and canker disease. Fungicides are used for curing these diseases. The major pests affecting these ornamental plants are aphids, thrips, Japanese beetles, and caterpillars of lepidopteran insects. Chemical formulations are used in order to terminate these injurious pests as they affect plant growth as well as economic yield.

The Black Rose - A Magical, Mythical Beauty


The mythical allure of black flowers has fascinated our attention for centuries. Black tulips and black roses appear to originate from a make believe fairytale world. A pure black flower is the Holy Grail of plant breeders worldwide. Their unnatural color inspires a powerful feeling of mystical expectation. If you were to receive a black rose bouquet, it could mean a variety of things. Possibly you had become a widower recently and you received the flowers as a token of bereavement, or perhaps it was a tell tale sign that you had offended someone and the dark bouquet was sent as a sign of revenge of retaliation.

In the time of the Edwardians at the cutting edge of fashion in the 19th century used to collect them, going to exceptional extent to track down these exotic species of flowers. Will this mysterious flower once more, at the dawn of a new century and a new millennium, become a source of artistic and philosophical inspiration? The black rose bouquet is also the beloved flower of Art Nouveau designers at the previous turn of the century.

The reality of the black rose is that it does not really, naturally exist. The so-called black tulip is actually very dark purple and the black rose is, in fact, very dark red. These flowers are quite popularly used in "Gothic type" environments or as a black rose bouquet in a wedding where the color palette is of a darker form. There are other less common cut flowers which occasionally occur in "black" forms - they all ooze decadence, mystery, fascination.

With their very unusual velvety soft petals, looking at a black rose bouquet will make you think of the comfy soft cushions of a luxurious and exquisitely decorated winter room. The scent of this mysterious black rose makes you float away to your favorite imaginary exotic place that is filled with the lovely aroma of these gorgeous black beauties. You can imagine, laying on a bed of black rose petals being fed by a gorgeous harem of worshippers fanning you with a big feather plume.

Creating a black rose bouquet is not simple, nor is it impossible either. To keep up with the dark, mystical feeling of the black, one of the greatest groupings is black roses mixed with ivy berries. They are available at the florists throughout the winter. The red-black color of the rose, with the blue-green black of the very creates a perfect harmony. Ask your florist of the darkest roses they have. See if they have "Black Magic", "Barkarole", "Black Beauty" or "Baccara" black roses. A completely black bouquet is very dark but impressive. It does, however, set off an air of somberness. Adding in glowers or greens with a red or brown tint can enrich the black color and give the bouquet a little more pizzazz and depth. You can also add some hypernicum or chili pods to give the bouquet a firey red tone. If it is around the holidays try putting a little sparkle into your bouquet by adding silver spray painted leaves. It will really jazz up your dark black rose arrangement. For More Rose Information

Growing Roses From Seed


Congratulations! This is an admirable way of growing roses. Although being able to grow roses from seed can be tricky and requires more patience than most areas of gardening, you can't beat the feeling of seeing something mature successfully from a tiny seed.
The Seed
There are packet varieties and seeds from rosehips, the fruit of the rose plant. If you're going to go down the growing from seed route why not go as natural as possible and use rosehips from a friend's rose or a wild one as you're walking along somewhere, you may be surprised at how many you find. Look for them after blooms have fallen and pick the, 'rosehips', when they look their ripest. Once they start to wrinkle they're beginning to dry out and not at their best. Please be careful as these rosehips itch, treat them like chillies.
Preparation
There are different methods but I've had the most success by using a combination of methods and that's what I'll share with you. Split the rosehips to expose the, 'seeds', they're creamy white and not actually the seed, they're inside but for what we need we will treat them as seeds. Clean these seeds thoroughly removing all the flesh.
Now place them about an inch apart on a damp towel, leaving plenty of towel around the edge of the seeds to be able to fold over without disturbing them. Place this folded damp towel in a sealable plastic bag and place in your fridge. This is the stratification process and is used the trick the seed in sprouting, leave for five or six weeks and check for any root tips that might be emerging. Leave for longer if they're not and check weekly for any changes.
Transfer
Once you have some that have sprouting roots transfer them to a pot or container. This can be real tricky so tweezers may help, damp the towel if you're struggling and that will free them off nicely. The seeds need good drainage, moisture and warmth so black plastic containers are best. Transfer these little sprouting seeds to the soil in your container making sure to leave a space of an inch all around them and about a quarter of an inch deep. Make sure that whatever potting soil you're using that it's sterile before you expose the seeds to it. Water well making sure they drain adequately also. When the seedlings are a few inches high you can transfer them to their own individual pot, they can take a few years to reach maturity by then becoming a big bush but they will flower before then.

The Rich History of Wild Roses


Wild roses, of the genus Rosa, are those naturally occurring natives found in Northern Hemispheres around the globe. Wild Roses can be found in forests, canyons, logged wastelands and thickets. They have continued to grow throughout the course of history and across a range of different terrains. Most modern day roses we know are mixed offspring of these wild roses.
Wild roses have had a rich history. They played roles in Greek and Roman culture, symbolizing themes such as love and allegiance. Later they became sought after for cosmetic, medicinal and religious purposes as well. However, with the beginnings of large-scale worldwide trade, rose horticulture and hybridization took root. This forever changed the wild rose landscape from a relatively small number of wild roses across the planet's surface to today's world with thousands-upon-thousands of rose varieties.
There are plenty of advantages to cultivating wild roses in modern-day rose gardens. Wild roses are strong, disease resistant plants, which can be grown in almost any less-than-ideal location. They are not dependent on regular fertilization and can tolerate some drought. Requiring essentially no care, wild roses are able to spread on their own, can handle being crowded and withstand transplanting at almost any time of year.
Some popular varieties of wild roses include:
Rosa Nutkana
An arching shrub with pink petals, the rosa nutkana grows in milder climates. Though it is fairly weather-tolerant, this shrub is best cultivated in sunny and well-drained locations. Prune often as thickets grow quite quickly.
Rosa Rugosa
This species, native to China, Korea and Japan, has been made into a number of different rose cultivars. It is a fast growing pink flower with rose-hips resembling small tomatoes. It prefers full sunlight and well-drained acidic soil. Since it is a salt-tolerant plant, it is an ideal shrub in coastal conditions. Light infrequent pruning will help keep growth of the Rosa rugosa under control.
Rosa Foliolosa
This is a member of the rosaceae family and is also know as leafy rose or prairie rose. The rosa foliolosa is a lovely little rose found mainly in Central and North Central Texas, Oklahoma and Arkansas. It is small in size with very thin wood, very elegant little foliage, with usually nine tiny leaflets per leaf. One of its great characteristics is its fern-like bright green foliage.
Rosa Blanda
Another member of the rosaceae family, the rosa blanda, also known as meadow rose is a shrub-like thornless plant which grows to about three to four feet tall and prefers rich soil in full sun to light shade. It produces lovely pink flowers between June and August and the fruit resembles small apples.
