Soil with a pH of less than 6.0 is called acidic soil. Hydrangeas growing in more acidic soils are less able to absorb nitrogen, phosphorus, and potassium, and will produce blue hydrangea blooms. If you have acidic soil and prefer a pink hydrangea, see our Planting & Care section for tips.

Soil with a pH of more than 6.0 is called alkaline soil. Hydrangeas growing in more alkaline (or basic) soil are less able to absorb phosphorus, iron, and manganese, and will produce pink hydrangea blooms. If you have alkaline soil and prefer a blue hydrangea, see our Planting & Care section for tips.

A bud is an undeveloped leaf, stem, or flower that will bloom later. Endless Summer® Hydrangeas develop buds on old wood and new wood, giving them their re-blooming quality.

Compost is decomposed plant material that enhances the nutrients in soil to improve the development of plants. For more information, please see the Planting & Care section of our website.

The crown is the section of plants where the stems and roots meet. It is the top part of a root system, and should be taken care of when planting. For planting tips, please see the Planting & Care section of our website.

Dead-heading is the process of removing dead flower heads from hydrangeas. This can be done to allow for new growth in spring, summer and early fall. Old blooms can be left on your shrubs for winter interest, if desired, and deadheaded in early spring.

Humus is an organic substance that develops from the breakdown of plant material. This can happen naturally in soil, or by producing compost. It is an important element in loam soil composition.

A lacecap hydrangea shows flat, round flower heads with a center of subtle, fertile flowers surrounded by an outer ring of more showy blooms. The Endless Summer® Collection showcases the Twist-n-Shout® lacecap hydrangea.

Loam is the best type of soil for gardening. It has a balanced mix of humus, sand, and clay. To test what type of soil you have, try the Jar Test

Mophead hydrangeas boast beautiful balls of blooms. Large, rounded blooms are typically 3 – 5” wide and can be a variety of colors.
