Hydrangeas are one of my favorite flowers. I have always loved them growing up and enjoyed adding them to my decor. You can imagine my excitement and surprise when I moved here to Cape Cod and quickly learned that practically everyone here has at least one in their landscape. I knew that I had to learn about them and add them to my gardens. But little did I know that selecting hydrangeas would yield so many options or how to choose hydrangeas correctly.
As many of you know, we moved into a new home a couple of years ago and I discovered there were a few hydrangeas already here. Since putting down roots here, I have slowly been adding and learning how to grow hydrangeas each season. A big part of the success and failures for me, is making sure that I am selecting the proper hydrangeas that meet their growing needs. This post today will focus on the different types of hydrangeas in my very own landscape here on Cape Cod.
How to Choose Hydrangeas
Know Your Growing Zone
Hydrangeas are native to Asia and also the United States. First, determine your growing zone. Knowing your growing zone will determine if you can grow hydrangeas in your location. Your zone will affect which varieties will be successful.
The next step will be to determine the amount of sunlight in your planting location. A spot is considered to have full sun if it receives at least 6 hours of sunshine. Shade receives at least 3 hours of sun and partial sun/shade is considered to be somewhere in between.
Size and Space
Lastly when selecting hydrangeas, it important to determine how big the mature, fully-grown plant can fit into the space you have allotted. But worry not, because there are perfectly sized hydrangeas for your needs, from dwarf varieties that remain compact, growing to a mature size of 2 to 3 feet both wide and high, to hydrangeas that tower up to 8 feet. I should also mention that some varieties actually enjoy living in containers too.
Types of Hydrangeas
Grow in Zones 4-9
Bloom on both old and new wood
Can take some shade in Southern US gardens they will require it. Other locations, they enjoy at least 6 hours of sun
Bloom early summer through fall.
Selecting Hydrangeas: One of the most common varieties are the Annabelles
Mopheads and Lace Caps
Grow in Zones 6-9
Mopheads have large globe-like clusters of sterile blooms
Bloom late spring through fall
Lacecaps have a flatter bloom surface with tiny fertile flowers in the center, surrounded by sterile blooms.
The blooming clusters are pyramidal in shape and are a combination of both sterile and fertile flowers.
Most of the blooms change color as the season progresses.
Bloom on new wood
Selecting Hydrangeas: I love Limelight and the smaller version- Little Lime. The blooms begin as a creamy color and progress to a wonderful lime green and they transition to a beautiful pink. Quick Fire is also another favorite.
Grows in Zones 5-9
Native to the United States
These are known as Oak Leaf hydrangea due to their leaf’s appearance.
Does well in heat and humidity
Foliage turns red in the fall. All the blooms start out some degree of whitish, creamy light green color and fade to varying degrees of reds and pinks as the season progresses.
Selecting Hydrangeas: Smaller favorite varieties include Pee Wee and Ruby Slippers.
Grow in Zones 6-9
The leaves are serrated and turn to red as the season progresses.
These are a good choice for places with later spring frosts as they leaf out later in the spring.

I have a young summer crush. I live in n. Idaho. (Zone 7b) I then planted it in a pot and put it on our covered porch, which gets 4 to 6 hours of filtered light and about 3 hours of direct sun. Also got a medium mulch. Have been lightly watering 3 days and giving it a good soaking drink the other days. Anything else I could do to make it happy ?
Oh how nice. I would give it time and see if it is happy where you have placed it. Without photos it is hard to tell but feel free to email me some and I can help as you need.
