Rose Plant Information

Roses Buds

The following will explain many rose plant information. Budding is a term rosarians use when a portion of one plant is grafted onto the rootstock of another — as opposed to growing on the original plant’s roots.

This has been a fairly popular way of propagating roses, especially among commercial growers. You look puzzled. You’re wondering why?

Many commercial growers believe that roses just grow better using this method. First, the plants themselves take less time to establish their root systems.

And the growers enjoy a larger percent of roses thriving on the rootstock than they do with roses on their original stock.

The growers simply take the canes (or branches) from the one rose plant, cut off the bud eye at the junction of the cane and leaflet and then insert it under the bark of the cane of a rootstock plant. A simple, uncomplicated operation.

When the canes and foliage above the bud are cut off, all the plant’s energy is then focused toward making the newly budded eye grow.

Bud eyes from the desired variety have all the genetic material to create a new plant that’s identical to the original.

The point at which the bud is inserted into the bark of the rootstock plant is called the bud union. On mature plants, the bud union looks very similar to a knob. As the plant grows in your garden, though, new, large canes grow from directly above this bud union.

In the colder climates, the bud union is the portion of the plant that’s most important to the plant’s survival during the harsh, winter months. As you learn later, you’re going to plant the bud union several inches below the ground in the cold climate and then protect it by covering it with a mound of soil.

Rose Flower Petals

She loves me, She loves me not!

Hmm. Remember that old game you used to play with wild daisies? With each “she loves me” or “she loves me not” you’d utter, you’d pull a petal of the flower. The last petal told the truth. So how often did she really love you?

No one would ever dare play such a destructive game with a rose. Yet, the rose — depending on its variety — has a host of petals — sometimes too many to count.

And sometimes, they’re just unique. Take, for example, the famous Green Rose. Formally called the Rosa chinensis viridiflora, the flower of this rose is green. But, upon closer examination, rosarians explain that what appears to be petals of a bloom is actually a host of sepals.

The petals of the rose.

rose petals

Normally, a rose bloom is defined as having a minimum of five petals. But as you’ll soon learn from the vast varieties of roses, this is seldom the case. In most cases, roses have more — many more — petals than just five.

In some cases so many petals exist on a single bloom that there are literally too many for the bloom to open fully except in the hottest of weather.

In many cases, the number — as well as the color — of the petals are just so fabulous that even if the plant blooms only once during the summer. . . Well, it was well worth the wait just to witness this gorgeous flower.

The most common of the petal formations — and yes, there is some uniformity and commonality to these! — fall into three major categories: single, semi-double, and double or sometimes called fully double.

The single formation is explained in its name. It’s simply a single row of petals — and yes, the most usual number of petals is five.

The semi-double formation contains only two –sometimes three — rows of petals with 12 to 16 petals in all.

The double formation or fully double formation contains lots of petals. A bloom is considered as part of the formation if it has more than 17 petals.

Sometimes you’ll find several more formations. And this is where the names get a little tricky and can cause some confusion. Some rosarians call a fully double formation of any flower that has between 26 and 40 petals.

If you speak with other rose hobbyists be aware of this overlap in names. But some roses have even more than 40 petals (imagine the beauty!). These are normally called “very double.” (No, I agree it’s not a very imaginative name, but it fits the description!)

And then there’s the arrangement of the petals.

While we’re on the topic of petals, let’s go into just a little bit more detail. Because in addition to the classification of roses by the number of roses, these beauties are also classified by the arrangement of the petals as they unfurl. (Do you ever think that rosarians just love to classify things?)

But, it’s true. And this classification comes into use when the flowers are in exhibition.

Many-petaled rose flowers with great or formal form are often called exhibition roses. These blooms are gracefully shaped whose petals are symmetrically arranged in an attractive circular outline coming to rest in a high pointed center. Yes, indeed, it is really a thing of beauty.

The arrangement of this unfurling of petals is judged on the symmetry as well as the spacing of the gaps. The center of the bloom — for judging purposes — should be well-defined, rising high within the flower and pointed.

From the side, you should notice the natural symmetry of the structure. The petals unfurl — ideally – uniformly from the center.

The outer row of the petal should be as close as possible to a horizontal plane.

Of course, each variety has its own inherent characteristics, as you might expect. But each exhibition rose is at its unique perfect phase of bloom when it is between half and three-quarters of the way open.

When you’re growing a garden, decorative or an informal rose, the bloom itself is not held to quite the same high standard. The flower itself is not as well-defined as an exhibition rose, nor does it need to be as high or as pointed in the center.

Ruffled, sometimes called wavy petals, as well as cupped, those turned inward are accepted. This variety also has fewer petals than most of the other classifications.

If rose forms are so important, just exactly, you’re wondering right now what affects the formation of the petals themselves. Well, if you’re thinking that it’s mostly genetics, you’re right… to a point

Three of the most important factors — after genetics — in rose formations are climate conditions, cultivation and the exact weather conditions as well.

A rose of substance.

Petals are also viewed and judged by their substance. This is defined by the petals’ stability and durability. Most importantly — and this should come as no surprise — substance is also judged by how long it retains its quality in a vase.

The substance of a rose petal also depends on the amount of moisture the petals have absorbed. But, perhaps most importantly, the substance is demonstrated in the texture, firmness, crispness, thickness, and toughness of the petals.

You can determine the substance of petals for yourself. Touch a petal. Go ahead, the chances are it’s not going to fall to pieces (not if it has any substance at least!). Is the petal thick? Look at it closely. A true petal of substance has an opalescent sparkle and sheen to it. And if it’s a red rose, it’ll have a velvety appearance to it.

The color of petals

Of course, rose petals are also judged by their colors. The elements that contribute to the petals degree of cover are . . . dare I say elementary. As you can imagine the bloom whose petals are bright, clear and vivid are usually prized more than others.

But in addition to that, the hue of the color is a factor as well. This factor includes the visual impact the petals have on the eye as well as how it distinguishes itself from other colors.

To this end, rosarians refer to something called chroma. This is the intensity and purity of the hue. Ideally, the petals should have no gray or white in their hue. And in fact, the idea petal of substance would be an amazing blend of brightness and chroma.
