'Grand Hotel'. Large-Flowered Climber. So mixed is the parentage of Modern Garden Roses that the results of a particular cross can be difficult to predict. Sam McGredy, seeking the huge, fire-red flowers of 'Schlossers Brilliant' on a sturdier plant crossed it with the Modern shrub Rose 'Heidelberg' and got 'Uncle Walter' in 1963. It was so vigorous that it was reclassified as a Modern Shrub - and as the plant matured the flowers shrank to middling size. Try again, thought Sam, and in 1972, the same cross produced 'Grand Hotel'. The flowers are what was hoped for - large, brilliantly red and shapely. But this time the plant is an out-and-out climber. Grow it for exhibition; it repeats quite well. Foliage is dark green and susceptible to black spot. 'Schlossers Brilliant' x 'Heidelberg'. Repeat flowering.
