Unique' is a medium-sized deciduous shrub with ovate leaves and unique flowers mostly large, sterile, white, ageing to purplish-pink, borne in massive, broadly conical panicles from late summer Growing Details: Common Name: Hydrangea Unique Genus: Hydrangea Species:paniculata Skill Level: Beginner Exposure: Full sun, Partial shade Hardiness: Hardy Soil type: Well-drained/light, Clay/heavy Height: 2.5m Spread:2.5m Description: Hydrangea can be deciduous or evergreen shrubs, or self-clinging climbers, with flowers in clusters usually comprising both small fertile and more showy sterile flowers; often good autumn colour Colours & Soil Acidity: In most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these species the colour is affected by soil pH. For H. macrophylla and H. serrata cultivars, the flower colour can be determined by the relative acidity of the soil. Hydrangea flowers are blue in acidic soil with a pH of 5.5 or lower. The more alkaline the soil, the pinker the flowers will be. Weather can influence the color of hydrangea leaves, causing large areas of purple discoloration. Cool weather near the end of the growing season may trigger the plant?s dormancy early, allowing the purple leaf color to show through as the green chlorophyll factories shut down for the season.
