The Edwardian era can therefore be looked upon as the first great era of the Hybrid Tea. ‘Gustav Grunerwald’ was one of hundreds of similar varieties and has come down to us today not necessarily as one of the best, but certainly as one of the strongest. Undoubtedly its breeding has something to do with this tenacity, for one of its parents ‘Mme. Caroline Testout’ is perhaps one of the strongest and most famous Hybrid Teas in existence.
Scent is one of ‘Gustave Grunerwald’s best attributes, and without question this factor won it popularity over many of its contemporaries. Another asset is tidiness, for it makes a shapely bush with fine foliage. The flower is attractive in colour, being carmine-pink with a tint of lemon becoming apparent at the centre when the petals are older and the flower is fully open. Held on a strong neck, the flowers are large enough for the show bench, and the twenty-eight petals hold their form well when cut. Fairly free of disease, this rose is worth growing even by gardeners who are not experts. Providing that liberal pruning is exercised in order to keep the bush from becoming leggy, it will grow quite happily without further attention.

Alister Clark. Save the Roses. I have had good seedlings from Gustav Gunnerwald [sic] and ... to name a few, and yet cannot now procure plants of them. It is easy to see that we may lose Roses that are invaluable for breeding.
