    • Scale drawings
    • Plant lists
    • A materials list
    • Cost estimates.
  • Develop criteria for selecting rose varieties to grow as a commercial crop, for a specified purpose.
  • Evaluate rose flowers offered for sale.
  • Determine factors which are critical to the production of various rose products, such as:
    • Cut flower roses
    • Rose hip syrup
    • Rose oil
    • Dried rose petals
    • Nursery stock roses.


Scope

Roses are one of the most popular ornamental plants in a garden, valued highly for their blooms which many would claim are the most beautiful flowers in existence.

Roses are grown for many reasons, including:

    • as a cut flower
    • as a landscape specimen (garden plant)
    • for perfume extraction

Rose culture deals with living things and there are many variables involved; not only the environmental and soil conditions, but also the type of rose grown, and the treatment it is exposed to.


A Potted History of Rose Cultivation

The oldest garden roses are hybrids or ‘sports’ of species roses that originated from the Middle East and Europe from as far back as the 13th century. Up until the mid 1800’s the range of varieties was very limited and there was not a great deal of controlled hybridizing done on plants (it was the work of the farmer breeder (animals) that greatly influenced later work in plant breeding).

Controlled hybridizing of roses began at the beginning of the 19th century. The roses that were selected and bred during this time were determined by what was the fashion of the day (much as it is now). For example quartered roses were out of favour in the beginning of the 20th century, only to make a return many years later with the much loved David Austin hybrids (collectively known as ‘The English Rose’). New varieties that arose before controlled hybridizing began were the result of chance crosses, or chance mutations known as ‘sports’.

The hybrid perpetual rose became the favourite rose during the mid 1850’s and was often referred to as the ‘Rose of England’. The two rose types (Hybrid and Perpetual) were not known as separate species until 1884 and then began to achieve some popularity as bedding plants (roses were adapted through pegging to achieve this). Hybrid Perpetual roses were derived from a Portland x China hybrid ‘Rose du Roi’ of 1816. This rose was then crossed with Bourbon and China varieties giving rise to thousands of vigorous, repeat flowering varieties. By the end of the 1900s the production of new Hybrid Perpetual roses declined.

Hybrid Tea roses (also known as Large Flowered roses) were the last of the major nineteenth century groups to evolve; they remain a most important group today. In around 1884 Hybrid Tea roses were finally recognised as being a separate class. The first member of the class was ‘La France’, a cross between a Hybrid Perpetual (‘Madame Victor Verdier’) and a Tea rose, (‘Madame Bravy’) – it was raised by Guillot in 1867. The first members of the Hybrid Tea class were almost sterile making cross breeding difficult. Later fertile Hybrid Teas were bred and from these many new varieties emerged. In the 20th century breeding programs progressed and produced roses with a diverse range of colours and form and improved health.

The Floribunda (Cluster Flowered) rose is the result of marrying a Hybrid Tea with the Hybrid Polyantha rose. It sounds quite simple these days but in reality took many years to achieve. In the 1860’s the R. multiflora (now used mainly as a rootstock) was introduced to Europe. From this species evolved a climbing rose and one of a dwarf form. It was the dwarf form, when crossed with a dwarf pink China Rose that produced the Polyantha Hybrids – roses with clusters of small flowers.

 

 



 

How to Grow, Propagate,  Care for and use Roses.
 
Looking to enter the field of rose growing or to further your career potential?
Then further your knowledge with this unique and comprehensive rose growing course, aimed at both  professionals and amateur growers. 

 

The value of rose blooms extends beyond the ornamental garden; roses are grown for many reasons including: the cut flower trade, for perfume extraction, to harvest the hips and for rose oil. This course covers all these aspects and much more. Learn the history of the rose, the confusing rose classification system, how to identify the different species, their general cultural needs (soils, pests and disease management and pruning), how to use roses in garden design and how to produce a commercial rose crop. 

Roses, often referred to as 'The Queen of the Garden', are one of the most popular and prized ornamental plants. They are included in the greatest gardens in the world and many claim roses to be the most beautiful flower in existence. 

This course could set you on the path to success.
