Who wouldn't want to relax with a cup of coffee on this patio, gazing into the brilliant white flower heads of that sensational hydrangea bush? A type of hydrangea that I, myself grow that has large white flower heads is 'Incrediball,' which I tell you about in this article: http://landscaping.about.com/od/shrubsbushes/p/Incrediball-hydrangea.htm
Smooth Hydrangea 'Incrediball' (Hydrangea Arborescens) - Zone 3-9 Part Sun (south) to Full Sun (north) Heat tolerant. 4'-5' tall/wide. Prefers moist, well-drained soil-mulch well and don't let them dry out. Deciduous, cold-hardy bush blooms from summer to fall on new growth. Large, over 12" across, flowers open green, then mature to white before fading to green again. Very sturdy stems hold the blooms upright even if soaked with rain. Propagate by cuttings.
