Mrs. Sam McGredy  Medium - Salmon to red. Remontant. P2. H4
There has never been another rose quite the same as 'Mrs Sam'; which is not only a familiar abbreviation of the name, but also a rose grower's description of the coppery red colour of its buds.  The flowers opened all too soon to a kind of stale salmon, quite uninteresting, but while they were young there was no rose equal their colour before or since.   
'Mrs Sam McGredy' is no longer sufficiently robust to plant, except as a climber; bushes of it seem to issue an irresistible invitation to blackspot, although there are still many surviving. It was found remarkable for the purple red of its young leaves.  One of the beauties of a rose nursery is seen by its staff and few others: the colours of the leaves at first growth, block by block, variety by variety, green, olive, red, purple, few exactly the same, and the whole winking in the sun like the newly minted treasures they are.  Purple leaves lose some charm by turning green as they age; then the contrast on the same plant of purple red above and green below may not be handsome.
'Mrs. Sam' has flower shoots which are usually thin, and the plant is very often a floppy affair. It was introduced in 1929, and raised from ('Donald Macdonald' x 'Golden Emblem') x (seedling x 'The Queen Alexandra Rose').  The story goes that when Mrs McGredy knew of the intention to use her name for a rose, she chose this one, and insisted on it against the advice of the men. She could not have found a much more famous rose from the whole of McCredy's output up to 1950. 
The great seed pods of 'Mrs Sam' make promises without keeping them, and I never heard of any breeder finding much therein, or fixing that colour in a better plant, or for the flowers full life.
