Crug Farm say:  One of our original seed collections from theMt.Unzenarea ofKyushu,Japanin 1998. Of a very floriferous dwarf form of this amenable deciduous lacecap species hydrangea, bearing corymbs of strong blue lace-cap (pink in alkaline soil) flowers May-August. While the foliage ages to a purple cast if exposed to sun, as in the field where we grow the mother plants, which are still only a meter tall without pruning at around 10 years old. Easily grown in any type of drained fertile soil with a bit of moisture retention, in either sun or shade, but more moisture retention required
