Hydrangea O Amacha Nishiki Hydrangea serrata 'Omacha Variegata'
Other Common Name(s):
- Description
-
Omacha Variegated Hydrangea serrata is a compact cultivar of hydrangea with unusual leaves. The foliage is heavily dusted gold with red stems which make this shrub an interesting specimen in a lightly shaded garden. Fall color of the leaves is a showy red/burgundy. The lacecap flowers begin white and turn pink or blue depending on soil acidity.
Little pruning is required for this hydrangea and should be done after flowering as it blooms on the previous season's stems. Weak or winter-damaged stems should be pruned away in early spring.
Although this plant can be grown in sun or partial shade, it is a native of Asia and prefers cool growing conditions and will grow best in light to open shade. Plant it in a location with full morning sun and afternoon shade in fertile high organic matter soils. In warmer climates, a location protected from hot sun will keep the foliage and flowers from prematurely fading or scorching and it will flower more prolifically with consistent summer watering.
