Ah, the famous hydrangea. Have you ever known a flowering shrub as vibrant, varied, or vast? This plant thrives in most parts of the country, and you’ve no doubt seen a variety or two around. And they’re popular for good reason—with over 75 species and a multitude of colors and styles, the hydrangea is one of the most diverse plants we carry!
However, because of its impressive range of varieties, it’s normal to wonder which hydrangea type you should plant (or even what kind of hydrangea is already in your yard!).
We’re here to answer all your questions about the types of hydrangeas, from the most obscure to the most popular.

What to Know About Hydrangeas
There’s much to know about hydrangeas: their growth rate, how to plant them, and their sunlight, soil, water, and pruning needs. What makes them thrive? How can you make your hydrangea bloom more proficiently? Let’s explore some fast facts about hydrangeas, so you can determine the best care for yours!
Basic Types of Hydrangeas
There are several main types of hydrangeas. These groups are different from the many varieties (we’ll get into those later).
Oakleaf Hydrangeas
This hydrangea variety is known for its oak-like foliage (see picture above). Not only do its leaves look like the deciduous tree, but they also glow with the autumn shades in the fall.Oakleaf hydrangeas thrive best in warmer zones, especially Zones 5 and higher, because they can withstand the summer heat.
Bigleaf Hydrangeas
The bigleaf hydrangeas are the most common among gardeners. As their name implies, they are characterized by their huge leaves (see above). This hydrangea variety is most often found growing in Zones 5 through 9.
Panicle Hydrangeas
Probably one of the lowest maintenance of all hydrangea types, the panicle hydrangeas are hardy to Zone 3. You can spot a panicle hydrangea by its cone-shaped blossom (shown above). A variety that’s both woody and strong, these easy growers can be pruned to look like trees.They can also reach up to 15 feet tall!
Smooth Hydrangeas
Smooth hydrangeas are called “smooth” for their blossoms’ smooth, round shape. Also known as “snowballs” for their white-bloomed varieties, these plants are an excellent choice for cold climates. And they can tolerate full sun, unlike other hydrangea types, if they receive plenty of water.
Mophead Hydrangeas
Mopheads are actually a subtype of bigleaf hydrangeas. Their flowers can bloom in purple, pink, and blue, depending on soil pH. Alsovery low maintenance, the mophead hydrangea variety requires absolutely no pruning. Their blooms are huge—as big as, well, the head of your mop.

General Care for Hydrangeas
Different hydrangea varieties may require specific needs, so it’s always good practice to double-check any planting or care instructions that come with your plant. However, below we’ve included some general guidelines for most hydrangea plants. (You can also check out our blog post onHydrangea Careto see more in-depth advice.)
- Plant your hydrangeasin areas with partial sunlight,prioritizing morning sun (afternoon shade can be too powerful).
- Hydrangeas typicallyprefer fertile, well-draining soilwith plenty of moisture.
- Water your hydrangea wellabout once per weekthroughout the growing season (and add more water during droughts or prolonged dry periods).
- Hydrangeas don’t always need to be fertilized.Just check the soil and variety type to find out whether fertilization is necessary.
- Pruning will depend entirely on which type of hydrangea you have.The bigleaf types will require pruning in summer after flowering. Others will need to be pruned in late winter before spring growth. Some won’t require pruning at all
Hydrangea Sizes
How big can a hydrangea get? Size can vary among types, but it’s always recommended you space hydrangeas at least a few feet to allow for growth.
Some hydrangea varietiescan grow up to fifteen feet in height! Others stay fairly compact, so ensure that youresearch your specific varietybefore committing to a certain location in your yard, potted container, or garden.
Hydrangea Blooming
As with any flowering plant, you want to enjoy its blossoms’ beauty and color for as long as possible! So, which hydrangeas bloom the longest? Many varieties flower in early spring and can continue blooming into fall or early winter.
While it does depend on the level of care as well, the longest-lasting hydrangeas tend to be reblooming hydrangeas (see our suggestions below). These flower on both new and old growth, meaning you get vibrant colors for a majority of the year. A popular group of reblooming hydrangeas are theEndless Summer hydrangeas—aptly named for their long blooming season!
What Kind Do I Have?
Identifying your hydrangea can be quite simple. You can generally decipher the type of hydrangea by:
- Leaf shape
- Whether it’s a climbing plant
- Number of leaves
- Flower colors
- Petiole length (or the stalk that joins a leaf to a stem)
Take note of each of these features, and then use them to do a quick online search. This information will almost always lead to plant identification. Once you know the variety name, you can begin caring for it appropriately.
