There is no doubt that Sam McGredy has set the standard when it comes to the real hard commercial side of rose-growing. No other grower has ever come anywhere near Sam McGredy IV for placing roses on a commercial basis...... He is about the only grower in the world who would say in all earnestness that he could produce a world-beater - if the price was right. But then he has already given that guarantee - and proved he could do it. The giant Mullard Electronic Company wanted a world-beater - and were prepared to pay for it. Sam offered them a cerise hybrid tea - and said it would be a world-beater. The price was ten thousand pounds. The rose was registered as 'Mullard Jubilee' for Europe and 'Electron' for America and it went out to take its chance against all the other roses which were being placed on trial throughout the world. It wasn't long before its vigorous growth, clear colour, flowering-producing power, and fragrance brought rewards. It won medals everywhere it was tried - and topped its career by being named the All-American Rose Selection for 1972. Overjoyed Sam McGredy exulted: It's as good as a licence to print money!".

Electron - in addition to being a 1973 AARS winner, this bright rose-pink Hybrid Tea also holds seven of Europe’s highest awards from Great Britain, Holland, Spain, Scandinavia, Germany, Austria and Belgium. The pointed buds of deep rose-pink open to large, high-centered blooms blessed with a most appealing, long-lasting fragrance. In fact, this rose won the award for “best perfume“ at Roeulx, Belgium. The vigorous, bushy and graceful plants are clothed with dark green foliage to the ground and bear an abundance of roses that retain their brilliant pink colouring throughout all stages of bloom.  A most decorative and valuable garden variety due to the shapely, attractive plants that constantly bear great quantities of exhibition type blooms from spring till fall. The parents of ‘Electron’ are ‘Paddy McGredy’ x ‘Prima Ballerina’ and it was bred in England. It has been introduced by the Howard Rose Company.

Dr. Thomas, Victoria.  The New Ones. 
Mullard Jubilee. HT. (McGredy, 1967) has been on sale in Australia for two years under the name of 'Electron'. It was known by this name but was not registered. A Canadian multimillionaire took a fancy to it and paid the raiser a huge sum of money to have it named for his family, celebrating the jubilee of the founding of their business. The original Mr. Mullard migrated from Northern Ireland to Canada. Strangely, 'Mullard Jubilee' was its first registered name and now a second registration has been accepted - 'Electron' under which name we have had it for two years. This is re-naming and with full official blessings!  It is a shapely, deep pink cultivar.

The only other Gold Medal awarded last year was to 'Mullard Jubilee'. it is a rose with no faults although the flower colour breaks no new ground. The trend for big business to celebrate important dates by adoping a new rose is quite new and I feel sure that Mr. McGredy hopes that other large firms will not take this challenge lying down.
