About this plant

Big Daddy Hydrangea is a deciduous shrub prized for its large leaves and abundant summer blooms from June through August. Flower color shifts between blue, pink, and purple depending on your soil's pH, making it endlessly adaptable to your garden's design. It excels as a foundation anchor, backdrop hedge, or statement piece in large containers, and thrives in USDA zones 6 through 9. Keep in mind that it is toxic to dogs, cats, and horses if eaten, and a large quantity can upset a person's stomach.

Your 3-gallon hydrangea arrives in a nursery container, ready to install. Upon arrival, choose a spot with part shade (morning sun and afternoon shade work best) and plant it within a few days. Water deeply after planting and keep the soil consistently moist while the root system establishes.

Where Big Daddy Hydrangea Earns Its Space

Morning sun with afternoon shade keeps those big leaves and summer blooms looking good.

Foundation row

Space plants 5 to 6 feet apart along the house for a full, rounded edge.

Shady hedge

A line of them makes a 5 to 6 foot backdrop for astilbe and heuchera.

Color-shift bed

Soil pH decides blue, pink or purple, so check yours before planting.

Cut-flower patch

June to August flowers can be cut for the house, and a big container works too.

Not ideal for: It struggles with drought and dry afternoon sun, so avoid hot, unwatered spots.

Good to know: Dogs, cats and horses can be poisoned by eating it, so site it beyond their reach.
