Classification:
The present invention relates to a new Gaura lindheimeri plant.
Variety denomination:
The new plant has the varietal denomination ‘Benso’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct variety of Gaura having pale pink flowers and dense plant habit. The new cultivar is known botanically as Gaura lindheimeri and will be referred to hereinafter by the variety name ‘Benso’.
Asexual reproduction of the new cultivar was first accomplished using softwood cuttings in a propagation nursery at Wonga Park, Victoria, Australia. Since that time, through successive generations, the characteristics of the new variety have been determined stable and reproduced true to type.
SUMMARY OF THE INVENTIONThe following traits in combination distinguish the ‘Benso’ variety from all other commercial varieties known to the inventor. ‘Benso’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions.
l. Gaura lindheimeri ‘Benso’ exhibits pale pink petal color.
2. Gaura lindheimeri ‘Benso’ exhibits dense plant habit.
COMPARISON WITH PARENT‘Benso’ is a naturally occurring branch mutation discovered in a controlled planting of Gaura lindheimeri ‘Siskiyou Pink’ (unpatented).
‘Benso’ is distinguishable from the parent by its flower color and habit.
In comparison, the plant most similar to ‘Benso’ is Gaura lindheimeri (unpatented). ‘Benso’ differs from this variety in a more dense habit and pale pink flower color as opposed to Gaura lindheimeri's white flowers. In comparison to ‘Colso’ (co-pending U.S. Plant patent application Ser. No. 10/160,592), of the same parentage, ‘Benso’ differs in not having variegated foliage and having a pale pink flower color. ‘Crimson Butterflies’ (U.S. Plant Pat. No. 13,189), although also having the same female parent, has a shorter plant height and darker flower color than ‘Benso’.
BRIEF DESCRIPTION OF THE DRAWINGThe accompanying illustration depicts plants of the new variety in color as true as possible in color photographic illustrations of this nature.
FIG. 1 shows the plant of the new variety.
BOTANICAL DESCRIPTION OF THE PLANTThe following is a description of the new variety ‘Benso’. Data was collected from plants grown in outdoor conditions, 9 months of age, in flower, at Wonga Park, Victoria, Australia during the month of April. The color determinations are in accordance with the 1995 Edition of The Royal Horticultural Society Colour Chart (“R.H.S.C.”), London, England, except where general color terms of ordinary dictionary significance are used.
The growing requirements are similar to other Gaura.
