DETAILED BOTANICAL DESCRIPTION

(7) The following detailed description sets forth the distinctive characteristics of ‘FLR12-89’. The data that define these characteristics were collected from asexual reproductions carried out in Morocco. The plants were 2 years of age when the data was collected. Certain characteristics may vary with plant age. ‘FLR12-89’ has not been observed under all possible environmental conditions, and the measurements given may vary when grown in different environments. Where means are given, the sample size was 10. Color descriptions are based on The Royal Horticultural Society (R.H.S.) Colour Chart by The Royal Horticultural Society, London, Fifth Edition, 2007. When The R.H.S. Color designations differ from the accompanying photographs, the R.H.S. color designations are accurate.
