Patented Roses

A rose variety may be patented just like any other plant. A patent grants to the holder exclusive rights to distribute and propagate that variety of rose. Of course the patent holder can license others to distribute and propagate that rose. A patent lasts for 17 years, so most older roses aren't currently under patent. After the patent has expired, anyone can distribute and propagate that particular variety.

Some nurseries divide their roses into patented roses and non-patented roses, with the patented roses costing more. This is because they may freely propagate the non-patented varieties, but their is usually a fee for propagating patented varieties.

It is illegal to asexually reproduce a patented plant, even for personal use. It is, however, legal to use a patented rose in hybridizing.

Peace

There are two roses available in Australia. The Hybrid Tea Peace is the most popular rose in the world. It was smuggled out of France just before the Nazi occupation and introduced just after the end of the World War II. It produces large blooms of yellow blending to pink on the edges. It is not very fragrant. The Tea rose , named for the end of the Boer War in 1902, is semi-double, in similar colours to the HT, and is a sport of G Nabonnand.

Pillar Rose

Indicates a form, not a class of roses. Roses grown as pillars have flexible canes of five to twelve feet which may be trained around an upright support (it does not have to be an actual pillar). Roses suitable for use as pillars are moderate in growth so that they will not overwhelm their support.

Pistil

Female organ of a flower. The pistil includes the stigma, style, and ovary.

Planting

It is best to prepare the ground about 6 weeks before planting, with compost or cow manure dug through the whole rose bed. It is preferable not to use Roundup on the bed in this time.

Powdery Mildew

A fungus disease, powdery mildew strikes under cool, humid conditions. Leaves will become covered with a whitish residue and may be curled and distorted. Powdery Mildew is not normally a serious affliction in that plants do not normally succumb to the disease. However, it is certainly unattractive. A spray of powdered milk diluted 1 in 10 can be used to reduce it. Good airflow through a rose garden helps.
