M R M. H. HORVATH retired from his active landscape activity in the year 1918, 
and since that time has devoted his entire time to the development of new, 
worthwhile plants with the constant purpose in mind of making the world a 
more beautiful place to live in. Early in his career he spent eleven years in the 
service of the City of Cleveland as designer and adviser to the Park Board, carrying 
on the activities of the Landscaping Department of the City Parks. Then, for a 
number of years, Mr. Horvath devoted his time to a private practice in both 
Forestry and Landscape Architecture. He developed and maintained during this 
period many of the great estates, both private and public, in the City of Cleveland 
and in the eastern section of the United States. 
During his work in one of these large estates he discovered one day a form of 
Berberis Thunbergi pluriflora with a strong tendency toward erect growth. He 
picked the seed from this plant and from the seedlings grown selected the most up¬ 
right types from which he again picked the seed. This process was repeated until 
the fifth generation wherein Mr. Horvath found the perfect, spire-like plant that he 
was seeking and which is now offered to you as 
TRUEHEDGE COLUMNBERRY
