TRIALS REPORT 2006 Perpetual Flowering Carnations Trials Office The Royal Horticultural Society Garden, Wisley, Woking, Surrey, GU23 6QB
AGM AGM Perpetual Flowering Carnation entries recommended for the Award of Garden Merit (H1) The Perpetual Flowering Carnation Trials Sub-committee recommended the Society's AWARD OF GARDEN MERIT (H1), given to plants which have proved to be excellent for garden use, to: Kiro = 'Lonkirok' PBR AGM(H1)2006 Sent by Mr S Bailey Petals yellow. Kiro was recommended for an AGM by the majority of the members present 6:1. The recommendation was proposed due to the outstanding quality of the flowers, the vibrant colour, form and its ability to provide flowers throughout the year together with a clove scent. Available from sender Other plants included in the trial, but not recommended for the Award of Garden Merit: Sangria was not recommended for any award as it was unable to provide flowers for every month although the flowers that were provided were usually good quality. Rififi was not recommended for any awards although the committee found it to be a consistent performer with a strong scent it was felt that form and colour did not reach the standards we wish to achieve.
Lady Green was not recommended for any awards as it was unable to produce blooms throughout the year and it was felt there were better green carnations available. Florence Franklin was not recommended for any awards although it produced flowers for most of the year the flowers were small and the plant appeared to be reverting to Ann Franklin from which it sported. Clifford Pipperoo was recommended for further assessment. This variety performed consistently over the course of the trial producing more flowers Dec/Jan/Feb than any other variety with the exception of Rififi. It was felt the flowers were perhaps on the small side but were of good colour and form, consistently produced and on good stems. Worth another look! The ongoing trial is assessing six further varieties for 2005 2007. Already some striking flowers have been noted! Thanks must go to the RHS for providing the facilities for the trials to be undertaken and to the staff who have kept the plants growing so well throughout the trial as well as the trials office for their support and advice.

Trial Notes Objective: Culture: The purpose of this trial is to ascertain the qualities of the plant and flowers on a given period of time and to ensure that they are in fact perpetual flowering. Cuttings were taken in October and rooted in 100% perlite. These were grown on, stopped once (pinching out the leader at the sixth node to encourage the production of side shoots) and potted into 9cm (3½") pots. They were received at Wisley at this stage in February 2005. In May the plants were stopped and potted on into 10cm pots, using a peat-reduced compost with added vermiculite. In mid July 2005 they were finally potted on into 25cm pots. The plants were supported by canes and plastic rings. Blooms were removed as they faded, snapped off at the sixth node below the flower on younger plants or at the eighth node on older plants (this varied according to the quality of breaks and to the cultivar being grown). The glasshouse temperature was maintained at 9 C (48 F) minimum and plentiful ventilation given to maintain a buoyant atmosphere. A balanced (1:1:1 NPK) liquid general fertiliser was applied at each watering. A pesticide was applied against red spider mite as required. Entries: Records: Findings: There were six entries submitted for trial as listed below. A record of the number of flowers produced each week and how long each one lasted was kept throughout the two year duration of the trial. During the course of the trial attacks of red spider mite occurred on all plants as well as an attack of rust. There were also minor incidences of virus, which were found not to be a serious problem. A graph of cut flower numbers for each month during 2005 and 2006 can be seen below.
