Scion

The leaf stock or shoot which is grafted to rootstock.

Semi-double

A rose with 12 to 24 petals.

Single

A rose with 4 to 8 petals.

Species Rose

Roses which are self-fertile, and if self-pollinated will come true. Another term used is "wild"; species roses are those which have evolved naturally to adapt to their native habitat. Most flower only in spring, and will sucker if grown on their own roots.
There are no roses native to the Southern Hemisphere. Some species of roses have become declared weeds in Australia (and New Zealand); the dog rose R canina and the sweetbriar. Roses are considered as pest plants in terms of rubbish removal, and may not be included in "green waste" or plant trimmings intended for compost for general sale.

Sport

Genetic mutation in a plant. Sports in roses are not unusual, and many new introduced varieties are sports as opposed to hybrids. Sports may be evidenced in different flower colors, flower form, and growth habit. For example, Souvenir St. Anne's is a semi-double sport of Souvenir Malmaison, and Climbing Souvenir Malmaison is a sport of this relatively small Bourbon.

Stamen

Male organ of flower. Pollen comes from the anther.

Substance

The amount of moisture in the rose's petals. While it is difficult to ascertain how much moisture is in a particular rose's petals by touch, thickness and firmness are keys to determining substance. A rose with substance will last well after being cut, thus, it is important that exhibition roses (or roses you would like the family to enjoy in the house) have good substance.

Sucker

There are 2 types:
- Stem or shoot growing from the rootstock instead of the grafted variety. Suckers should be removed at their base, by pulling downwards.
- A new plant growing from a root, from a plant which is growing on its own roots (ie not budded onto a rootstock). Some roses can become invasive this way. In general, most roses which flower in spring only (except most ramblers), especially species roses including R bracteata, and gallicas, will do this. Rugosas will also sucker if grown on their own roots, and can become invasive. These plants are best bought budded. or grown in a large tub.
