Blooms do not open fully, usually occurring in areas with cool, damp nights. Roses with many petals are more susceptible to balling, thus many old roses are liable to ball on occasion. If you live in an area where your roses ball more often that you would prefer, choose roses with fewer petals.


Roses sold in a dormant state, without soil around roots. This is the most common method of shipping roses, usually in fall, winter, and early spring.

Basal Cane

One of primary canes of a rose plant, originating from the base of the plant.


Rose bloom with two distinct colours, one on the front of the petals, and the other on the back.


The bane of many a rose gardener, blackspot is a fungus that causes black spots about 1/16 to 1/2 inches in diameter to form on the leaves and sometimes stems. The infected leaves later turn yellow around the spots and eventually fall from the plant. In bad cases, blackspot can severely defoliate a rose bush. Blackspot thrives in warm, humid weather. Rather than constant spraying to control this plague, plant resistant plants and practice good husbandry (sun, water in the morning, burn diseased canes, periodic cleaning of shed leaves, and plant at proper spacing for good air circulation).
It is best to choose roses that don't show black spot when grown in a nursery in your area.

Blind shoot

Stem which fails to produce a flower.

Bud Union

The point where the grafted canes join the rootstock on budded (grafted) roses. Very easy to determine due to the swelled appearance of the union. Bud union is important for determining how deep to plant the rose (varies by region).


Method of propagating roses by grafting a leaf bud in to the neck of root stock.
