Rose Part 2: Modern Garden Roses

In 1867 Jean-Baptiste Guillot developed a rose, ‘La France’, when he crossed a Tea Rose with a Hybrid Perpetual. This plant known as the Hybrid Tea rose began the age of the Modern Garden Rose.

Most plants in this class are repeat-bloomers with rich and vibrant colours but do not adapt well in cold climates and are very susceptible to disease and pests. Modern Garden Roses are also further classified into several groups.

Hybrid Tea Roses

This flower with its single long stemmed bloom available in every colour but blue and black is the standard rose used in the floral industry.?á Because of intense inbreeding to create a flower with perfect form many Hybrid Tea’s no longer have a scent or the disease resistance and hardiness of its ancestors.

'Die Welt'

'Lady Aberdeen'

Floribunda Roses

This rose was created with the desire to a have a more compact, hardy and disease resistant plant. Floribundas have the look of Hybrid Tea Roses but blooms prolifically from summer to fall.

'Atlantic Star'

'Macivy'

Grandiflora Roses

Crossed between the Hybrid Tea and Floribundas, the flowers of these roses are larger and cluster on top of taller stems usually as a double bloom.

Old Garden and Modern Garden Roses make up the majority of plants in the home rose garden. They can be further classified by colour, size, blooming characteristics, scent or growth habits but the categories I’ve described are the standard for the American Rose Society making it easier for the average gardener to keep them straight. Here are a couple more types of roses that you may see in landscaping.

Miniature Roses

'Pink Bells'

'Pink Bells'

All of the classes of Old Garden Roses have miniature versions. They range from 3″ to 18″ tall with continuous, scentless blooms in every colour available. Most miniatures are marketed as houseplants but will do quite well in outside containers, in rock gardens or as border.

 

   

'William Baffin'

Climbing Roses

All roses have ‘climbing’ forms where stems grow longer and more flexible than the bush forms. With Modern Roses this is usually due to a mutation while it is a natural growth habit of many varieties of Old Roses. Climbing roses are repeat bloomers and can grow anywhere from 8′ to 20′ in height. However these plants are not considered vines because of their inability to cling to support themselves. Instead they must be trained and tied to structures like trellises and pergolas.

Shrub Roses

Shrub Roses, also know as Landscape Roses, were created from the demand by gardeners who prefer roses that offer the colour, fragrance and form of Modern and Old Garden Roses but are low maintenance and easy to care for. These roses have good disease and pest resistance, a lower growth habit and continuous blooming making them a great choice for mass plantings.

With all the choices of roses out there gardeners will have no problems picking out the plants that have the best characteristics for them and still create a gorgeous visual display.

Roses Part 1: Old Garden Roses

Any rose that has been recognized before 1867 is considered an Old Garden Rose. Native to Europe and Asia they are generally pastel in colour and most varieties only bloom once per year usually representing the arrival of summer. Yet because of their long history, their resistance to pests and disease and their ability to adapt in poor weather conditions, they have been considered the most versatile of all the roses.  Due to crossbreeding of specimens from Europe and Asia, Old Garden Roses are further classified in one of the following groups.

'Tuscany'

'Tuscany'

Gallica Roses

One of the finest, these roses have a long lasting show of red, pink or purple blooms with a very intense fragrance. The plants have attractive dark green foliage and stems with few thorns.

'Mme. Hardy'

'Mme. Hardy'

 

 

Damask Roses

Summer Damasks will only flower once in the summer while the Autumn Damasks are the only Old Garden Rose that will produce a second flowering in the fall. These plants develop fragrant flowers in white, pink or red.

'Prolifera de Redoute'

'Prolifera de Redoute'

 

Centifolia or Province Roses

Also known as ‘cabbage roses’, these one hundred petaled flowers came from the Dutch and can be seen in much of their earlier artwork. Being the most fragrant of all the roses they are still cultivated today for their perfume.

'Blanche Moreau'

Moss Roses

Named for the mossy growth on their flower stems, sepals and buds, these roses are just a mutation of the Centifolia rose.

 

'Semiplena'

Alba Roses

The Latin word meaning white, these roses date back to ancient Rome. White or pale pink blooms contrasting against the blue-green of their foliage made these popular with the artists during the Renaissance.

 

'Hermosa'

'Hermosa'

 

 

China Roses

It was these roses, when brought over to Europe that resulted in the creation of the first Modern Roses. China Roses bloom repeatedly throughout the summer and fall months.

 

Old Tea Roses

Grown mainly in France, Old Tea roses were developed from cross breeding two tea-scented China Roses. Producing almost thornless stems the flowers of this rose can be found in white, light yellow or pink.

'Comte de Chambord'

'Comte de Chambord'

 

Portland Roses

Usually pink in colour, Portland Roses are a multi cross between China, Damask, Centifolia and Gallica roses. Very fragrant, compact, sturdy and long flowering they are great for mass plantings.

 

'Gipsy Boy'

'Gipsy Boy'

 

 

Bourbon Roses

Another repeat flowering rose, these were created from the China Rose. If deadheaded regularly they will flower throughout the summer and into the fall.

'Barronne Prevost'

'Barronne Prevost'

 

 

Hybrid Perpetual Roses

With fragrant flowers in red, pink or white Hybrid Perpetual roses were the dominant roses during Victorian times in England.

 

 

Noisette Roses

Noisettes are repeat-flowering climbing roses with clusters of fragrant blooms in creamy shades of pink, yellow, white and apricot.

The Rose Festival

'Tequila Sunrise'

'Tequila Sunrise'

Beginning June 20th and running till July 5th the Royal Botanical Gardens will be celebrating their annual Rose Festival. During this peak flowering time, the Centennial Rose Garden in Hendrie Park will be showcasing some of the most beautiful examples of over 2,000 modern garden, old garden, shrub, miniature and climbing roses. Take a stroll along the Rose Walk to see examples of companion planting with roses in the home garden. During the weekends of June 20th, 21st, June 27th, 28th and July 4th, 5th you will be treated to live entertainment, garden tours and children’s activities.

Over the next 2 days I will be focusing on the differences between the different types of roses and hopefully you will get a better understanding about these garden favourites.
