Hydrangeas are one of my favorite flowering shrubs to watch transform through the seasons, and they never fail to make a statement in any landscape. If you're wondering about how tall these beauties can grow, most hydrangeas range from 3 to 15 feet tall, though certain types, like panicle hydrangeas, can even reach up to 25 feet. With such diversity in size, there's a hydrangea variety fit.
In the wild, bigleaf hydrangeas can grow taller than 15 feet (5 m) tall, while they stay about half that size in the garden.

Hydrangeas are deciduous ornamental shrubs perfect for outdoor gardens. They have beautiful blooms that come back every summer for several decades when grown in suitable environments. Hydrangeas like 6 hours of direct sunlight with protection from harsh midday sun, especially in hotter climates.
They grow actively at temperatures between 60 and 75 °F (15.6 and 24 °C) and shed leaves below 50. Hydrangeas grow relatively quickly compared to other shrubs, but they can become overgrown if they grow too big. To help them, ensure they get enough sunlight and prune them to encourage new growth and a stronger base for future blooms.
Compact hydrangeas that grow under five feet tall make beautiful container plants, which require at least four hours of morning sun daily and frequent watering. 2.
