DETAILED BOTANICAL DESCRIPTION

(7) The following is a detailed description of the new cultivar as observed on 1.5-year-old plants new Sempervivum as grown outdoors in 8.5-cm containers in Westerlo, Belgium. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S.

Root description.Rhizomes grow from main rosette and hold offsets, rounded in shape, average of 2.5 cm in length and 1.5 mm in width, texture smooth, glabrous and matte, 200D in color. Propagation.Cuttings. Root development.A cutting will root in about 2 months when taking in summer and will fully root in a P9 container in about 6 months from a rooted cutting. Growth rate.Moderate. Stem description: Stemless. Foliage description: Leaf shape.Oblong, succulent. Leaf division.Simple. Leaf arrangement.Rosette. Leaf base.Broad cuneate. Leaf apex.Abruptly acute. Leaf venation.No veins visible. Leaf margins.Ciliate and un-lobed. Leaf attachment.Sessile. Leaf orientation.Flat to slightly curved upward. Leaf substance.Succulent, average of 3.5 mm in thickness.
