Shrubs : Other Details - Roses
There are a number of specific criteria which apply only to roses. One principal criterion is the use of BUDDED or CUTTING RAISED plants. Budded roses have the buds of the desired type worked on to a rootstock of a seedling rose. This is a traditional method of production, enabling a rose grower to propagate a wide range of cultivars on field grown rose rootstocks. The use of budded roses in extensive landscape planting is to be discouraged because occasionally the rootstock is inclined to ‘sucker’ , throwing long shoots of the seedling type growing from below the bud union. These are unsightly and if not removed can over-grow the budded variety. For this reason, roses grown on their own roots (propagated from seed or from cuttings) i.e. NOT BUDDED, are preferred for extensive landscape plantings. Rose species have historically been grown from seed (e.g. Rosa canina, Rosa rugosa, Rosa glauca). These seed raised roses are specified as for seedling and transplant shrubs.
In recent years large quantities of modern ground cover roses have been bred for landscape use. These have been developed in order that they can be propagated from cuttings, grown on their own roots and it is essential that they should be specified as such i.e. CUTTING RAISED.
Budded Roses
Budded roses are typically supplied after one season of growth after budding. They can be supplied in bush or standard form and these are available in two qualities, A and B. Any rose of lesser quality cannot be sold.
Root Protection
Budded roses are supplied bare root (bagged) or in containers. The root system must be well balanced and well developed. The minimum length of the roots from the budding point is 20 cm.
Container Size
Budded roses are supplied in a typical container size of C4. (4 litres container)

Standard From
Standards, created by budding the desired variety at the top of a straight stem (measured from ground level to the lowest budding point) grown from a rootstock, must have the following:
Stem diameter, measured 1 cm below the lowest budding point, of 1cm.
| Stem heights in cm. |

| 60 |
| 90 |
| 110 |
| 140 (for weeping roses) |

Minimum number of 2 grown buds with a maximum distance of 10 cm. between the two grown buds
Minimum number of 3 strong and matured branches starting from the budding point.
| Quality B |
|
| No. of Branches = |
min 2 |
Minimum 1 grown bud.
Minimum number of 2 strong and matured branches from the budding point.
Cutting Raised Rosed
Cutting raised roses are gaining in popularity for landscape planting and are typically supplied as one or two year old plants.
These are only available as BUSHES.
Cutting raised roses - Root Protection
Cutting raised roses are supplied bare root (bagged) or in containers. The root system must be well balanced and well developed. The root system must always be protected from drying out.
Cutting raised roses - Container Size
Cutting raised roses are supplied in a typical container size of C2 (a 2 litre container).
Cutting raised roses - Bush specifications
BUSHES and can be specified as follows:
Strong growing = minimum 3 branches
Minimum 3 branches starting within 10 cm above ground level.
Slow growing = minimum 2 branches
Minimum 2 branches starting within 10 cm above ground level.
