Hydrangea macrophylla ‘Nikko Blue’
An extremely popular flowering shrub, the Nikko Blue Hydrangea is a selected form of the Mophead Hydrangea (French Hydrangea) which originated in China and Japan. It is named after the Nikko, Japan. Nearly everyone is familiar with their enormous and colorful blooms. Appearing more pink in alkaline soils, Nikko Blue Hydrangea flowers are borne from June to frost. With their coarse deep green foliage, these flowering shrubs are excellent foundation or specimen plants, and their wonderful flowers can act as accents in a flower garden. The Nikko Blue Hydrangea does quite well in containers for use on decks and patios where proper shade exists. An all around excellent plant, the plant is relatively disease and insect resistant and wonderfully variable in bloom color by modification of soil pH conditions! To turn them their distinct shades of blue, acidify the soil by adding 2 tablespoons of aluminum sulphate to a gallon of water per bush. Pruning is not necessarily needed for the Nikko Blue Hydrangea. If you do feel compelled to prune, buds are set in late summer to early fall. Prune prior to this timeframe. Prune back to where you see healthy buds growing. If you prune after the buds have been set, you risk losing flowers for next year. Dead branches can be pruned out at any time.

| Flowers | Flower panicles (corymbs) are 4-8 inches in spread and 4 inches in depth. The flower color is strongly affected by the pH of the soil in which they are growing. The bluest shades are always produced on the most acidic soils. A pH range of 5.0 to 5.5 is listed as satisfactory for inducing blue coloration while pH of 6.0 to 6.5 and probably slightly higher is best for pink coloration. |
