Rosa damascena ‘Trigintipetala’
....The damask rose enjoys heat, water, and high fertility, and under these conditions it flowers well. Roses can be successfully grown on a wide range of soils but they do best on well-drained soils, with a soil pH of 6.0-6-5. Adequate water is essential throughout the vegetative and flowering periods, and where irrigation is needed, basal watering, such as drippers, are favoured as they avoid wetting the flowers at harvest time. The frequency of watering depends on the porosity of the soil and the seasonal weather conditions. Roses are gross feeders and enjoy high fertility conditions. Fertilisers containing nitrogen, phosphorus, sulphur and potassium are needed for high flower production, and the chosen fertiliser dressing should relate to soil analysis.
...The production block of Trigintipetala at Redbank was established with plants budded on R. multiflora stock.
....As they mature, the plants form hedgerows up to 2 m in height and have good wind
....No flowers are produced in the establishment year. The summer damasks only flower well on mature wood and pruning requirements are minimal. The production block at Redbank was left unpruned, and flower production levels continued to increase over three seasons as the plants
grew in size. Under Central Otago conditions there has been minimal incidence of pests and disease, and control strategies for pests such as aphids have not been warranted.
.....Trigintipetala flowers during November and December in Central Otago. The flowers are picked into sacks as early as possible each day on the basis of flower maturity. A flower is picked as it reaches full bloom and unopened buds and flowers are left for subsequent picking.
....Picking is extremely labour intensive. Although there is variation in picker efficiency, plant size and flower density, the best pickers have not exceeded 6 kg of flowers/hour, and typically the average is closer to 3 kg of flowers/hour. At 2.5-5.0 g/flower, this represents 200-400 flowers/kg. At
Redbank Research Station, the crop produced 5.6 kg of flowers/plant in the third flowering season. This equates to a total flower yield of around 9.2 t/ha at a density of 1650 plants/ha. The picked flowers should be chilled immediately to prevent heating, and distilled as soon as practical.
Two of the finest roses for perfumery are 'Professeur Emile Perrot' (to which the names 'Kazanlik' and R. x damascena 'Trigintipetala' are also applied and 'Gloire de Guilan.'

There are two types of essential oil producing roses cultivated in the Valley of the Roses. The Rosa damascena forma triginipetala(the pink/light red Damask Rose) and the Rosa damascena var. alba sometimes called Rosa alba(White Rose) The Damask rose is by the far the most important as it yields a higher quantity of oil and many people consider its quality superior(This is one of those things that is open to debate. The White Rose also produces a wonderful oil in both the essential oil and absolute form but it has its own unique qualities) The White Rose is a sturdier crop and is sometimes planted as hedgerows around the Damask Roses. They are also planted at higher elevations where the pink rose does not survive.
....Historically it is believed that Rosa damascena was brought to the Kazanlik area(located in the Valley of the Roses) from Tunisia in 1420 by a Turkish judge. At that time that part of Bulgaria was part of the Turkish Empire and the love of the rose had been well established in the hearts of the people of that region over several centuries. When the roses where planted in this particular valley, they grew extremely well and the emperor of that time Sultan Murad III requested the judge to establish more rose gardens for then needs of the palace.

The 'Kazanlik' rose, too, had been a mystery to me for years. I had received no fewer than three distinct roses under this name: one was a Gallica, one turned out to be 'Ispahan', and a third was identical with another rose I had been given labelled 'Professeur Émile Perrot'. This proved to be the real rose from Kazanlik, Rosa damascena 'Trigintipetala', the rose grown in greater quantity than any other in Bulgaria for the production of "attar". It is a similar type to York and Lancaster, R. damascena 'Versicolor', with spindly growth up to 6 feet or so, soft light green leaves, and rather small flowers, loosely double, of soft pink. In spite of its name this rose, over here at least, seldom has as many as thirty petals.
Through the kindness of Professor V.M. Staicov of the Bulgarian State Agricultural Institute for the Investigation of Mediacal and Aromatic Plants, who kindly sent me both herbarium specimens and, later, living material of the roses grown at Kazanlik, I have been able to elucidate the matter. ...Rosa damascena. This appears to be almost if not quite identical with my R. damascena 'Trigintipetala'.
