Rose Nomenclature 
By the Editor
As no doubt some of our members are aware, a very unsatisfactory situation with respect to Rose names has arisen within the past few years due to the practice of certain large commercial firms in re-naming Roses of European origin, contrary to and in defiance of "International Rules of Botanical Nomenclature" and its supplementary schedule known as Appendix VII (Nomenclature of Garden Plants).
Valid Name: Spek's Yellow
Re-christened: Golden Sceptre

Spek's Yellow. In colour, this rose has given the best yellow blooms we have seen.  We once remarked to a neighbour when she showed us a truly gorgeous bunch of trumpet daffodils that that was the color we would like in a rose. A short time later, we saw it in the first blooms of the Spek's Yellow. The early spring blooms possessed about 20 petals, but even then opened quickly. In late November we are lucky if we get 12-15 petals, and the blooms change from bud to full flower overnight. The bush has shown a marked tendency to black spot. However, the growth is vigorous and the flowers, freely given, come in sprays of 3 or more.

Speks Yellow also looks good. It is a medium sized decorative with long stems, a rich even coloured yellow and free flowering. There is room for another yellow such as this.

Nigel Raban,  The Men Behind the New Roses.  Andries Verschuren.
Two other Verschuren introductions must be mentioned here, which were the result of a combined effort with Pechtold. 'Spek's Yellow' ('Golden Rapture' x Seedling) was sent to the Trial Grounds immediately after the war and was given a T.G.C. in 1947. It was very well received by the gardening public and was the outstanding yellow bedding rose of its time, despite its rather untidy upright growth. The flowers, which are small but of excellent form, retained their golden colouring to the end and it was probably used more than any other yellow rose of its time for the artistic classes and for general decorative purposes.
