Genus and species: Bouteloua gracilis.

Variety denomination: ‘Blonde Ambition’.


The present invention relates to a new and distinct blue grama grass plant designated ‘Blonde Ambition’ and botanically known as Bouteloua gracilis. This new blue grama grass originated from a whole plant mutation from a ‘Hatchite’ blue grama grass (unpatented) found in a residential yard in July 2007 in Santa Fe, N. Mex. ‘Blonde Ambition’ was first propagated asexually by crown divisions in August of 2007 in Santa Fe, N. Mex. and has been asexually propagated over six generations. The present invention has been found to be stable and reproduce true to type through successive asexual propagations via crown divisions.

Plant Breeder's Rights for this variety have not been applied for. ‘Blonde Ambition’ has not been made publicly available or sold more than one year prior to filing of this application.


The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Santa Fe, N. Mex.

    • 1. The flower head emerges with a distinctive chartreuse color and ages to blonde as the seeds mature; and
    • 2. A tall plant habit at maturity.


This new blue grama grass plant is illustrated by the accompanying photographs, which were taken in Santa Fe, N. Mex. on an approximately two-year-old plant in August and September of 2009.

FIG. 1 shows an overall view of a mature grass plant of the present invention taken in September of 2009.

FIG. 2 shows a close-up view of the flower heads of the present invention taken in August of 2009.


The following description of ‘Blonde Ambition’ is based on observations of live and dried specimens taken in March 2010 in Fort Collins, Colo. The descriptions are of plants approximately two and a half years old. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), Fifth Edition (2007).
