Endless Summer Hydrangea
Hydrangea macrophylla ‘Bailmer’ · a reblooming bigleaf hydrangea
A reblooming mophead that flowers on both last year's and this year's stems, so it blooms from early summer into fall and survives colder winters than most bigleaf hydrangeas. The flowers turn blue in acid soil and pink in alkaline. Give it morning sun, afternoon shade and moist but not soggy soil.
