If you are puzzled that a beautiful red Hybrid tea should have a name associated with a whitish valuable metal, refer your problem to a firm called Johnson Matthew. From the numerous promising seedlings raised by Dickson, they picked a red rose to represent 'Precious Platinum'.

'Precious Platinum'  Medium   +   Bright crimson  Remontant    P2   H2   ****
A bold rose in brilliant deep red, vigorous, and generously adorned with glossy leaves. It was raised by Pat Dickson from 'Red Planet' x 'Franklin Englemann', and introduced in 1974. (Note: Englemann is the correct spelling, but the rose was wrongly registered as Engelmann.) 
The development of red Hybrid Teas on plants very different from those they had previously inhabited has been Pat Dickson's brilliant contribution to modern roses. Breeders in the past could not separate from the dark red colour, weaknesses of flower stems and leaves; it is assumed that the generative atoms which govern these characters are so closely linked that they have never been separated. Pat Dickson's breeding line was exemplified by 'Red Planet', a rose of  handsome growth and glowing crimson,  although I always  thought its flowers came good too seldom. 'Precious Platinum' shares the family likeness, but with much better flowers. The final hurdles remain, of darker colour and more scent, and if Pat can clear them, he will put us all very deeply in his debt. His present achievements are a great boon, because his red roses up to date are healthy.

Precious Platinum (Dickson). Deep but bright crimson with a fairly good bud. We are accustomed to good reds from this hybridiser. Seen both at home and abroad, this is a good rose though not necessarily for exhibition. Glossy foliage, fragrant blooms and good stems.

Precious Platinum HT. (Dickson, 1974): A fine plant with beautifully formed crimson blooms. It has been stated elsewhere that this is an alternative name for 'Royal Show' - this is incorrect.
