There are as many as 80 different species of hydrangea, according to some sources, while others only list 23. Regardless of the number, only six varieties are frequently planted in American gardens. Compare their qualities by looking at the details below.
What sort of hydrangea do I have, and how can I tell?
The aforementioned plant traits make it simple to distinguish between climbing and oakleaf hydrangeas, hence they will not be covered in this section.
Shape of the Flower Head
- A paniculata type is most likely present if the flower head is formed like a cone.
- It is either a macrophylla or an arborescens kind if the flower head resembles a ball or a flat disk. Visit the section on Flower Color.

Flower Color
- A macrophylla type is present if newly opened blooms feature blue, purple, or pink blossoms.
- An arborescens type is present if the flower buds initially seem green, then turn white, and finally turn green or greenish brown as they ripen.
- You likely have a macrophylla kind if the flowers are white when they first open and remain white as they age. Although they are less common, white flowered macrophylla varieties do occur.
Note: Recent breeding is beginning to develop arborescens with flowers that have a pink tint, such as “Eco Pink Puff.” Future cultivars should have a stronger version of this pink.
What various hydrangea varieties are there?
Also known as hortensia, florist’s hydrangeas, and French hydrangeas. The most typical variety of hydrangea to be found in the US is this one. Mophead, lacecap, and mountain hydrangeas are the three different varieties of hydrangea macrophylla. As long as the winter is not too harsh and dry, some mophead hydrangeas can survive in colder climates. After a prolonged warm weather, hydrangeas are most vulnerable when exposed to a freeze. Additional protection could be needed there.

Should hydrangeas undergo a fall pruning?
Only prune these hydrangeas in the summer after bloom, not in the fall. In August and September, old wood hydrangeas begin to form their bloom buds for the following year. It is advisable to delay pruning your hydrangeas until the following year if you don’t do it right away. If not, there won’t be any blossoms the next spring.
On which older trees do hydrangeas bloom?
Simply put, old wood is wood from the previous year. On stalks that have been part of the plant since the previous year, flower buds on hydrangeas that bloom on old wood are set in the late summer.
The mophead, bigleaf (macrophylla), lacecap, and oakleaf kinds of hydrangea bloom on ancient wood.
These gorgeous shrubs require very little pruning. If you must, though, knowing when and where to trim is crucial. That’s because the less flowers you have the following summer, the more old wood you take.
To keep your old wood hydrangeas healthy and vigorous, take the following three steps:
- Pruning flowering stems back to a pair of sound buds should be done as soon as possible after blooming, but no later than July.
- Remove weak or broken stems during the winter or early spring pruning. The oldest stalks should only be removed in thirds, cutting them to the ground.
- To maintain the shape of your shrubs and revitalize them, repeat the method each summer.
How many hues are there in hydrangeas?
Along with white, bigleaf hydrangeas come in hues of pink, red, blue, and purple. White types never change color; they always bloom white. Similar to this, red varieties—which are actually very deep pink rather than pure scarlet red—will typically maintain that color in all soils. The color, tint, and intensity of pink, blue, and purple options, however, can all change based on the soil conditions.
Which hydrangea grows best in the sun?
The majority of hydrangeas only like morning sun. The panicle hydrangea is the only variety of hydrangea that can remain in the sun all day. Although they can tolerate the sun, these also thrive in some shade. Additionally, panicle hydrangeas are the most resilient varieties.

When ought hydrangeas to be pruned?
Depending on which group the plant belongs to, the timing and extent of pruning are determined:
Advice on Pruning for Group 1:
- As the days get shorter and the weather gets colder in the late summer and fall, buds for the following year’s blooms start to form.
- Typically, removing dead, diseased, or damaged branches is all that is required to preserve shape, size, and a healthy plant. Otherwise, gentle pruning ought to be practiced.
- In the summer, trimming should begin as soon as flowering ends, but no later than August 1. Pruning should not be done in the fall, winter, or spring because you risk removing fresh buds.
- Tip-pruning the branches in the spring as the leaves begin to appear can promote more numerous, smaller flower heads as opposed to fewer, larger flower heads.
Advice on Pruning for Group 2:
- On the growth of the current year, flower buds form.
- Early in the spring, as the leaves are starting to emerge, prune.
- Just above a node, prune branches back by half to a third.
- After that, prune any fragile or spindly branches.
- Minimal trimming encourages huge, strong bushes with many of tiny flower heads in H. arborescens. Hard pruning between 12 and 18 inches from the ground, or even all the way down, will result in fewer but larger flower heads that may flop if unsupported.
- For H. paniculata, remove the surrounding smaller wood while leaving the larger stems in order to establish a sturdy foundation.
Pruning may be connected to flower head size. Shoots will grow more vigorously and flower heads will be bigger and fewer with more rigorous trimming. Smaller but more numerous flower heads may result from less aggressive or tip pruning.
Consideration of hydrangeas’ mature size is the best piece of advise. Place them in a location where they won’t outgrow and won’t need a lot of pruning to keep them in check. Hydrangeas don’t need to be pruned precisely or often; as long as dead wood is removed, they will remain healthy and continue to develop and bloom.
