Hydrangeas are large shrubs with beautiful masses of color. They fill gardens with their green, leafy foliage and incredible blooms during the warm months.

The two kinds of hydrangeas offer different looks to a garden. Mop heads have big round, dense balls of showy flowers that add a bold statement, whereas lace caps are more subtle and elegant.

The pink, blue, or white flower color of hydrangeas depends on soil pH, becoming bluer in acidic soils and pinker in alkaline conditions. White flowers will stay white.

Hydrangeas need minimal care in well-drained, fertile soil, and are shade lovers. They’ll grow to several feet in height and can be three to five feet wide. Newer cultivars that reflower are also available, which provide color again and again.
