How big do panicle hydrangeas get?
Panicle hydrangea is a large, multi-stemmed, woody, deciduous shrub or small tree that is rapid-growing and coarsely textured. It typically reaches a height of 8 to 15 feet tall and can grow up to 25 feet tall. This is a sun-loving hydrangea and is one of the few hydrangeas that flower on the current season’s growth. I figure, in the winter especially, even beige flowers are better than no flowers at all. If you need to prune your panicle hydrangea—and it can grow huge over the years, reaching up to 15 feet (5 m) in height and spread if you never cut it back!Panicle hydrangeas should be pruned in late winter or early spring, cutting back one-third of last year’s growth to promote fuller blooms. Oakleaf hydrangeas require pruning right after flowering in the summer, with light pruning to maintain shape while avoiding cuts in spring.To reduce the size of an established climbing hydrangea, prune it in spring. Climbing hydrangeas can cope with hard pruning, but are likely to produce fewer flowers for a year or two afterwards.Improper Pruning This is the most common reason that causes Hydrangeas not to bloom. Hydrangeas do not usually need to be pruned –ever- except to remove dead stems and blooms or if the plant is getting much too large. All Panicle flowering types, meaning cone shaped flowers, can be pruned late fall or early spring.

The other reason to grow these shrubs is the long period of flowering. In my gardens on Cape Cod, panicle hydrangeas come into bloom in July (early or late according to variety) and remain in flower into October. Hydrangeas that are grown in more sun than they like will often flag on hot days. They may recover at night, but if they continue to wilt every day, they may become stressed, making them more prone to damage from pests and diseases. And they’ll look tired with drooping flowers that often don’t attain full size.This timing will vary by region. For instance, in areas with winter freezing and snow, hydrangeas should be planted in early spring or early fall (as soon as summer heat breaks). In warmer regions with mild winters, the window for planting hydrangeas is longer, from fall all the way through to early spring.Ideally, they love a bit of sunshine in the morning, followed by some cool shade for the rest of the day. By this logic, the best place to plant a hydrangea is on the East side of your home.You can clip the dead flowers off the plant just below the bloom, or leave it on the plant into the winter. Most dried hydrangea flowers break off sometime in the winter and any that remain on the plant can be removed in the spring. Don’t “neaten them up”!
How long do hydrangeas take to reach full size?
However, most varieties of hydrangeas take two to four years to mature to full size. Dwarf hydrangeas that stay small are easier to prune and maintain than larger varieties. Over-pruning can result in a loss of flowers for the current growing season. Dwarf types need minimal or no pruning.
Do panicle hydrangeas like full sun or shade?
But panicle hydrangeas thrive in full sunlight. We recommend planting in a location that gets at least 5 hours of direct sunlight. In northern states, the plants can handle full sunlight all day. In southern states, it is best to provide a little shade in the afternoon if possible. Most common hydrangeas prefer a partial sun location – ideally receiving sun in the morning hours and shade in the afternoon. The reblooming Endless Summer® Hydrangea series prefers part shade.Summary: Pair hydrangeas with plants that match their light, moisture, and soil needs. Shade/part-shade allies (great with Bigleaf, Mountain, Oakleaf, Climbing) include Astilbe, ferns, Hosta, Heuchera, Brunnera, and Tiarella. For sunnier spots (Panicle, Smooth), try Daylily, Salvia, Nepeta, Echinacea, and Rudbeckia.
What if my panicle hydrangea is too big?
They will still flower if they are hard-pruned, but this often results in fast re-growth and larger flowers that weight the stems down. There are alternatives to trying to make a plant shorter, however. With panicle hydrangeas it’s often better to turn larger plants into small trees. I figure, in the winter especially, even beige flowers are better than no flowers at all. If you need to prune your panicle hydrangea—and it can grow huge over the years, reaching up to 15 feet (5 m) in height and spread if you never cut it back!Panicle and smooth hydrangea plants bloom on new growth, so deadheading can be a bit more extensive. You can cut with longer stems without reducing the potential for the numbers of flowers the following year, Foster says. These plants form flower buds on the growth that emerges in the spring.
Where is the best place to plant panicle hydrangeas?
Picking a perfect spot for panicle hydrangeas. Panicle hydrangeas are the most sun-tolerant of all hydrangeas, and in colder climates (say, USDA zone 3-6), we recommend at least four hours of bright sun each day; six or more is preferable, as it encourages the strongest stems and the most flowers. Where to plant. Ideally, plant your climbing hydrangea against a north- or east-facing wall or fence. A sunnier spot is fine, providing the soil doesn’t get too dry in summer. Evergreen Hydrangea seemannii and Hydrangea serratifolia need a sheltered spot as they are not fully hardy.Not all plants pair well with hydrangeas. Here are some combinations to avoid: Sunflower prefers full sun and hotter conditions than hydrangeas, which require some shade. Lavender is a sun-loving perennial that performs best in dry conditions and leaner soil, so will not thrive near hydrangeas.
