Hydrangea serrata ‘Preziosa’ (aka 'Pink Beauty') – 'Preziosa' is a mop head with deep pink domed flowers in summer that age to deep red-pink. As the flowers mature to glowing embers of crimson the foliage becomes infused with a strong red shade for a rich and striking late season show. I first saw ‘Preziosa’ planted in the fronts of homes when I visited Ireland during the month of September some years back. The images are indelibly imprinted on my mind. This cultivar is sometimes listed as ‘Pink Beauty’. On a personal note I fell in love with this older cultivar glowering in the Irish countryside. I fell in love with it as I fell in love with Ireland. For gardeners towards the northern end of its range spring planting is advised.
This species originates in the mountains of Japan and Korea. Though it is purportedly hardier than H. macrophylla we seldom see flowers in USDA zone 5b; as such we are listing all of the following cultivars as better doers in zones 6 to 9. The ovate to lanceolate foliage tends to be narrower than its close cousin, H. macrophylla. The smaller leaves support an over all more delicate appearance. And as with H. macrophylla there are also both lace caps and mop heads occurring in this species and will be noted below. We've seen this group also listed as H. macrophylla var. serrata. All prefer fertile soil to sandy loam. All of the following cultivars are cutting grown.
