Shrubs – 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.

Roses grown on their own roots propagated from seed or from cuttings are preferred for extensive landscape plantings.   Ground cover roses have been developed in order that they can be propagated from cuttings and grown on their own roots.  These are specified as CUTTING RAISED roses.

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.

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.

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)

Bush Form

No Branches Root Collar Diameter
Quality A min. 3 1.3cm
Quality B min. 2 1.1cm

Quality A must have a minimum of three strong branches, at least 2 of which start from the budding point with the third starting at the most 10 cm from this point.  Quality B must have a minimum of two strong branches starting from the budding point.

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  a stem diameter of 1cm (measured 1 cm below the lowest budding point) and stem heights of 40cm, 60cm , 90cm or 110cm (140cm for weeping roses).

No Branches Buds
Quality A min. 3 2
Quality B min. 2 1

Quality A must have a minimum number of 3 strong and matured branches starting from the budding point and a minimum number of 2 grown buds.  There must be  a maximum distance of 10 cm between the two grown buds.

Quality B must have a minimum number of 2 strong and matured branches from the budding point and the minimum 1 grown bud.

Cutting Raised Roses

Cutting raised roses are typically supplied as one or two year old plants and are only available in bush form.

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.

Container Size

Cutting raised roses are supplied in a typical container size of C2 (a 2 litre container).

Bush specifications

Strong growing bushes should have a minimum of 3 branches starting within 10cm of ground level.  Slow growing bushes should have a minimum of 2 branches within 10cm above ground level.
