S8.4 Roses
other details - origin and provenance - shape - 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, [see S2 for details].
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 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.
S8.4.1.1 Budded roses - 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.
S8.4.1.2 Budded roses - Container Size
Budded roses are supplied in a typical container size of C4. (4 litres container)
S8.4.1.3 Budded roses - Bush form

S8.4.1.4 Budded roses - Standard form
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.
