3 Trial Notes: Objectives: The objectives of the trial were to assess a range of Petunia hybrida multiflora cultivars; to evaluate weather tolerance and floriferousness; to recommend the Award of Garden Merit [AGM] to those considered excellent for ordinary garden use and to demonstrate the range of Petunia hybrida multiflora cultivars currently available from seed. Entries: There were 202 entries in the trial, submitted by various seed companies in the UK, Europe and USA. Cultivation: Seed was sown on 18 April onto pans of peat-free propagation compost and watered in with Revive (a product that containing natural soil micro-organisms which encourage soil fertility and healthy plant growth). Bottom heat of C was provided and the seed was germinated under mist. Seedlings were later pricked out into 6cm Jiffy pots of peat-reduced compost and grown on under protection. From the end of May the plants were gradually hardened off and then planted out on 7 June. The entries were spaced 40cm apart each way in blocks with 50cm between each entry. The Shock Wave and Opera Series, which were expected to be more vigorous, were spaced 50cm apart each way. 12 plants of the single coloured cultivars and 24 plants of the mixtures were grown. The plants had been quite small at planting out and there had been no selection for the best, but care had been taken at planting out to ensure good establishment. The plants had been watered in at planting, then irrigated with sprinklers the following day and watered again with a lance a couple of days later. Further irrigation had not been needed as the weather had then become very wet. Judging: The Floral Trials Sub-Committee assessed entries in the trial for the Award of Garden Merit on 24 July, 7 August, 22 August, 4 September and 19 September using the following criteria: floriferousness : earliness : longevity of flowering weather tolerance : disease resistance Findings: The cool, wet summer meant that this had not been a particularly good year for Petunia, although the multiflora cultivars had been bred for the open ground and were expected to have better weather tolerance than grandiflora cultivars. The Sub-Committee noted that most entries did recover when the weather improved and that many were still flowering in mid-september, with the plants withstanding the colder nights better than the Impatiens growing in other parts of the Garden. However, as anticipated, the heavy dews that are normal for September mornings caused spotting and damage to the flowers and flowering performance deteriorated with the cooling nights. At each assessment the Sub-Committee noted anything that marred the appearance of the plants, such as opening out, dying back or yellowing foliage 3

and spotting on the leaves or flowers. They also noted that different colours in some of the series were variable in habit, as well as in weather resistance.

Torrential rains towards the end of July had washed soil away from roots and resulted in the foliage being splashed with mud, but it was noted that the entries that had made good ground cover had not

4 and spotting on the leaves or flowers. They also noted that different colours in some of the series were variable in habit, as well as in weather resistance. The Mambo series was noted as consisting of compact, uniform plants with a good habit and the PrimeTime series as having notably healthy foliage. Torrential rains towards the end of July had washed soil away from roots and resulted in the foliage being splashed with mud, but it was noted that the entries that had made good ground cover had not been as badly affected by the mud splashes. When the Sub-Committee met in the morning of 24 July to assess the trial they found that the heavy rain had damaged the blooms and that there was virtually no flower on the majority of plants, Photo by Sue Drew 19 July July 2007 so they returned at 2pm to inspect the trial by which time fresh flowers had begun to open on a number of entries. A fortnight later the Sub-Committee found that the trial had recovered well from the torrential rains and was making a good display, Trial assessment 7 August 2007 although a shower on Monday 6 August, immediately followed by strong sunshine for the rest of the day, had resulted in many entries showing spotting on the flowers. The weather had again turned cool and wet towards the end of August so, when the Sub-Committee came to assess the trial on the 22 August, there was very little colour. However, the plants had again recovered to give a good display in time for their assessment on 4 September.
