A remarkable, double white. Medium - Tall - Plant 20" apart. These are invaluable in the hardy border, adding superb color in the autumn. Very durable and long lived. Even heavy, wet soils will suit them. All are 24-30" depending on the richness of the soil. Watch for powdery mildew beginning in mid summer, but good air circulation will go a long way towards preventing disease. Pinch back and divide like mums for best display..
