Kalanchoe plant

#The present invention relates to a new and distinctive cultivar of Kalanchoe plant, botanically known as Kalanchoe and known by the cultivar name Sirius, developed by me through controlled breeding by crossing the unpatented cultivar Mars (seed parent) x Rotkappchen (pollen parent), with the latter being disclosed in my U.S. Plant Pat. No. 3,851. Asexual reproduction by stem cuttings of the new cultivar has shown that the unique features of the new Kalanchoe are stabilized and are reproduced true to type in successive propagations.

#The following characteristics distinguish Sirius from both its parent varieties and other cultivated Kalanchoes of this type known and used in the floriculture industry:

#1. In comparison to Rotkappchen, my new cultivar Sirius is a more vigorous growing cultivar, being a taller and fuller plant by 20% or more when produced under the same growing conditions.

#The accompanying colored photograph illustrates the overall appearance of this variety taken as a top perspective view of the plant and showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type.

#The following is a detailed description of my new kalanchoe variety based on plants produced under commercial practices at the nursery of Wyss Samen und Pflanzen AG, Zuchwil, Switzerland. Color references are made to the Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.

#Parentage: Seedling of Mars x Rotkappchen (U.S. Plant Pat. No. 3,851), selected from seed crop of 1972.
