Hydrangea macrophylla 'Bailmer' ENDLESS SUMMER
Bigleaf Hydrangea (Hydrangea macrophylla 'Bailmer' ENDLESS SUMMER) is an attractive shrub with lush foliage and large, plump cone-shaped flowers that have white, pink, and blue varieties. Its leaves are deep green and very large in size, hence the name “Bigleaf.” It does best in areas with partial shade since too much exposure to direct sun can cause it to wilt. It’s also fairly drought tolerant, so it doesn’t need frequent watering. The Endless Summer variety of Bigleaf Hydrangea brings abundant blooms throughout the summer and well into the fall due to its reblooming characteristics. It adds a beautiful burst of color to any landscape or garden.
