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.
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.
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.

Arrived in perfect condition. I planted according to directions - then it just lost all its leaves. Contact with Plants by Mail said it must be shock and to give it time. I am not a novice at planting hydrangeas. I have never had this happed before

Plants arrived in perfect condition unlike some others I recently purchased from somewhere else. They look great for being planted for several weeks and I am anticipating beautiful blooms. Really people the shipper so many times is the difference in good or bad plants. I will buy again from you. Thanks!!!

The plants arrived in the same condition as all plants I have ordered on line. They are smaller than 2.5 qt plants seen at the nursery because they are safer to ship that way. As soon as they were out of their wrapper they expanded and are ready for planting in a larger container. I am happily anticipating these new blooms.

I am giving 3 stars because they are alive, but.....I would NEVER have purchased these 2.5 quart hydrangea plants if I had seen them in person. I am hopeful they will live and thrive, but I will never order from Plants by Mail again. I also ordered 2 gardenia plants....again, such poor plant quality and I never would have purchased had I seen them in person. I am an experienced gardener, so hopefully I can keep them going and thriving. Lesson learned.

Planted them just about a week ago, to early to review. I'll wait to see if/when the bloom to update my review.

Cant wait to see the color!

The plant I received looked like it was handled roughly or careless, with some broken branches, not in the best shape, but the plant itself looks healthy with no disease issues, nor dying. I put it in my garden and it seems it is adapting but slowly, probably due to the mistreatment.

My Heart Throb Hydrangeas arrived in great condition and very healthy. I've placed them in pots on my front porch. We recently had a hard freeze, so I moved them into the garage for protection, but have since moved them back to the porch. They are thriving and I can't wait for them to bloom.

Beautiful and so much color.
