• The cultivar name means fireworks in Japanese, in honor of its brilliant little white flower umbels. This cultivar falls into the lacecap group of H. macrophylla - which have flattened flowerheads, rather than the Hortensia type, which bear flowers in a full, spherical arrangement. The flowers on this cultivar are double and pure white. The deciduous foliage is an emerald green with a large tear-drop shape.
• Grows approximately 36" high and wide
• Hardy in Zone 5 - 10
• Hydrangea's are versatile, useful in containers as well as shrub borders or as specimen plants flowering in mid to late summer.
• This cultivar is easily rooted by leafy softwood cuttings taken in mid-Spring. They do well under mist and respond markedly to indolebutyric acid treatments. Leaf-bud cuttings can be used if propagating material is scarce, two cuttings being obtained from the two opposite leaves at each node. The media used can be of many profiles allowing for good drainage maintaining a favorable moisture level.
  

How to Grow: All hydrangeas grow in full sun or light shade and do best in a moist but well drained soil supplemented with peat moss, leaf mold or compost. Big-leafed hydrangeas require acid soil. They do well in seaside gardens and big-leafed hydrangeas flourish near the shore.

To acidify the soil, use aluminum sulfate, which provides aluminum as well as lowers pH, mixed 1 pound to 7 gallons of water. Soak the ground with it after the plant starts growing in spring and repeat twice at two- week intervals as necessary to lower the pH

1/2 point. To raise the pH 1/2 point, spread ground limestone in spring or fall at a rate of 5 pounds per 100 square feet

The time to prune hydrangeas depends on the species. The big-leafed hydrangea blossom from large buds formed on previous season's growth; thus any pruning, usually needed only to control height, should be done immediately after flowering.
