Latest Plant haven Patents:
The present invention relates to a new and distinct cultivar of Buddleja davidii and will be referred to hereafter as ‘Santana’. ‘Santana’ represents a new Butterfly Bush, a deciduous shrub grown for landscape use.
The new cultivar, ‘Santana’, was discovered as a sport that appeared on a plant of Buddleja ‘Royal Red’ (unpatented) in the garden of the inventor in North Yorkshire, UK in 1990. ‘Santana’ was discovered as a naturally occurring lateral branch mutation of Buddleja ‘Royal Red’ (unpatented). It was isolated from the parent plant and found to have stable, variegated foliage. The new cultivar can be readily distinguished from other cultivars of Buddleja davidii known to the inventor in that the leaf margins are a bright yellow to golden color. The two closest cultivars are ‘Harlequin’ (unpatented) and ‘Masquerade’ (unpatented); both have creamy-white leaf margins and purple-red flowers. Leaf margins of ‘Santana’ are wider than leaf margins of ‘Harlequin’ and ‘Masquerade’. The flower color of ‘Santana’ is purple-red and essentially the same as ‘Royal Red’, ‘Masquerade’ and ‘Harlequin’.
Asexual reproduction of the new cultivar was first accomplished by softwood cuttings in Knaresborough, North Yorkshire, UK on July 1990. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish this cultivar from other commercial varieties known to the inventor.
1. The foliage of ‘Santana’ has bright yellow to golden margins. The centers are dark green with some mottling of a lighter green. The golden margins are wider than comparative cultivars (3-5 mm). The leaf margins are 1-1.5 mm on ‘Harlequin’ and 2-3 mm on ‘Masquerade’.
2. ‘Santana’ has sweetly scented purple-red flowers.
3. ‘Santana’ is a medium-sized cultivar of Buddleja davidii, reaching 1.85 M in height with a spread of 1.5 M. Many cultivars can reach 3 M in height and 5 M in width.
4. ‘Santana’ can be distinguished from ‘Royal Red’ by its variegation with leaf margins that are 3 to 5 mm in width of a bright yellow to golden color. ‘Royal Red’ in contrast has leaves that are solid green with no variegation. The flower color and other general characteristics of ‘Santana’ are similar to those of ‘Royal Red’.BRIEF DESCRIPTION OF THE DRAWING

The photograph on sheet two depicts foliage variegation colors of ‘Harlequin’, ‘Masquerade’ and ‘Santana’ (right to left). The colors are as close as possible with conventional photography.BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new cultivar as grown in a 2 gallon container in North Yorkshire, England. The cultivar shown is a two year old plant.: Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determination is in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
