Description

The Heart Throb® Hydrangea is a new red hydrangea from the Southern Living Plant Collection. It produces beautiful cherry red bloom clusters with green marbling. These flowers emerge through summer and into early fall. This dwarf hydrangea reaches only 3 ft. tall and wide at maturity. No pruning required. Therefore, it's perfect for containers, mixed garden beds, low-hedges and mass plantings. They're hardy from USDA Zones 5 to 9. They grow best in part sun to full shade and need water 2-4 times per week for the first growing season, depending on the weather. They grow best in rich garden soil with good drainage. They are not guaranteed to be in bloom on arrival.

Heart Throb Hydrangea Care

Hardy from USDA Zones 5-9.

Plant in Partial Shade for best results. Several hours of sun in the morning with afternoon shade will support healthy bloom production.

Moreover, the Heart Throb can handle more sun than traditional mophead hydrangeas, but all-day sun may result in foliage burning.

Well-draining soil is important for avoiding root rot.

Water regularly after planting. 2-3 times per week for the first growing season. This will allow the roots to establish deep into the soil, helping to ensure future success. During this time, check the soil around the Heart Throb Hydrangea. If the soil is drying out or remaining soggy, you will need to adjust your watering schedule accordingly.

Fertilize with a balanced fertilizer in spring, and reapply regularly according to your fertilizers instructions. A high phosphorus fertilizer will encourage this hydrangea to produce more blooms. However, over-fertilizing will result in decreased bloom production.

Care & Use

Getting Started: Understanding Your New Plant

Review your plant's information on our website or the tag that comes with it. Be mindful of sunlight preferences, soil type, and spacing needs.

Our plants are adaptable but grow best in the correct USDA Zones. Click here to learn more about your USDA Zone.

Planting Instructions

Dig a Hole

First, dig a hole three times the width of the root ball of your plant. This makes it easier for the root system to spread out quickly. Dig the hole deep enough that your plant will sit level with or slightly above the ground around it.

Amend Your Soil

Mix your native soil with rich gardening soil to provide extra nutrients and support plant growth. If your soil is clay-heavy, we recommend mixing your native clay soil with equal parts of Pine Bark mulch to improve drainage and the overall breathability of your soil.

Place Your Plant

Examine the roots. If they appear tightly bound, gently coax them apart; this ensures they can spread into the new soil. Place your plant in the hole so the top of the rootball is even with the surrounding soil—Backfill around it with the amended soil mixture. The roots need access to oxygen for your plant to thrive, so do not cover the rootball; place soil around it.

Mulch Your Plants

Top the soil beneath your plant with 3-4 inches of mulch to help it retain moisture. Be careful not to cover the rootball - your new plants roots need access to oxygen.

Water Your Plant

Soak the plant with a hose afterward to hydrate the plant, as well as get the soil and mulch situated. Develop a regular watering schedule based on your plant's needs and local weather patterns. Remember, over watering is just as, if not more, harmful than under watering.

Spacing Recommendations

Spacing your Heart Throb Hydrangeas

Plant your hydrangeas 18-24″ apart from plant center to plant center for a seamless planting at maturity. Space them over 3 feet apart for
space between plants.
