C. H. Isaac, Vic.  Roses I Met in the United Kingdom
I fell in love with Violinista Costa at first sight. A bed of it, containing perhaps fifty plants, was in full bloom.  It reminded me of Shot Silk, the colour being much the same though a little deeper and the foliage shiny and disease resistant. There were several similar beds of roses but no other variety showed more than one-tenth of the bloom of Violinista Costa. Mr. Page assured me it had always been the same and that it stayed in bloom over a longer period than any comparable variety. He was most enthusiastic about its virtues.

Mr. Frank Penn, Remuera, NZ.  Random Notes. 
Violinista Costa will certainly become popular when better known.  It blooms splendidly as a "maiden", and gives a great crop of most attractive flowers of scarlet, shaded strawberry and gold - excellent in late autumn.  After two years trial I am very pleased with this variety.

Mr. Frank Mason, New Zealand Rose
Violinista Costa is another beauty and will be very acceptable when better known. It has the growth of President H. Hoover.

C. C. Hillary. Hayward’s Heath; England’s Test Garden.
Other named varieties in the test beds worthy of comment are: Violinista Costa, a large Rose in delightful shades of orange salmon and pink. While useless for exhibition, it should prove eminently suitable for providing decorative effects in the garden. The flowering is equally as profuse as that of Sunny South or Else Poulsen.
