One of the most popular single-flowered salmon-pink varieties is Lady Chesterfield - strong, sturdy habit, and fine in blossom. Surprise, another salmon-pink short stocky grower. A newer variety is Mrs. Robert Cannell, even better than Lady Chesterfield in colour, habit, and size of truss. Salmon Paul Crampel is another new variety.
F. V. Raspail, scarlet, splendid for cut; Hermione (nearly always written and pronounced "Hermoine"), white; King of Denmark, rosy salmon; White Abbey, white; Henry Jacoby, deep crimson; Gustav Emich, scarlet; La Cygne, white.
These have arisen from P. peltatum or P. hederoefolium, a South African species with five-angled or lobed ivy-like shining-green leathery leaves and white or red flowers. Numerous varieties - single and double - have been raised, but, unlike the bushy Zonals, they are all straggling and long-stemmed in habit. This makes them valuable for drooping over window boxes, for pegging down as carpet plants in beds and borders, or for baskets hanging from arches, porticoes, etc. They are raised from cuttings in the same way as the Zonals, but require perhaps a little more heat and more grit in the soil. The plants also are much more subject to attacks of greenfly, which cripple the leaves and spoil the plants. They must therefore be syringed with nicotine, soft-soap, and quassia emulsions, or the houses must be fumigated or vaporized from time to time. A fungoid disease, probably Botrytis cinerea, attacks the plants sometimes and destroys the foliage and blossom. The only remedy is to burn the affected plants, or to prevent the spread of the disease by syringing with liver of sulphur (1 oz. to 3 or 4 gal. of water). Of late years hybrids have been raised between the Ivy-leaved and the Zonal sections, and some of them will probably become market favourites.
The following varieties are grown largely: Souvenir de Charles Turner, deep rose, double; Madame Crousse, pink, double, with a brilliant scarlet form; Prince of Wales, cerise; Achievement, soft salmon pink; Galilee, beautiful clear rose; H. Cannell, rosy scarlet; Madame Thibaut, deep pink; Giacomelli, pale lilac; Mrs. Hawley, cerise; Queen of Balkong, deep scarlet; Willie, bright scarlet.
