Hydrangea Arborescens, Smooth Hydrangea (White) - Plant
Description for Hydrangea Arborescens, Smooth Hydrangea (White)
With immense billowy blossoms, hydrangeas flaunt an old-fashioned charm that is hard to resist. Colors also beguile with clear blues, vibrant pinks, frosty whites, lavender, and roseâ€”sometimes all blooming on the same plant.
The colors of some H. macrophylla flowers are affected by the relative availability of aluminum ions in the soil. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 product pink flowers. White flowers are not affected by pH.

Caring for Hydrangea Arborescens
- For the first year or two after planting and during any drought, be sure hydrangeas get plenty of water. Leaves will wilt if the soil is too dry.
Be cautious about planting hydrangeas under or near trees, as the large roots may not leave enough water and nutrients for the hydrangeas. Keep an eye on hydrangeas in these positions, and transplant them to a new area if they are struggling to grow or produce flowers.
