Understanding different hydrangea species is a great way to make the best choice for your garden. These flowers take on many forms, each with stunningly unique flowers and colours. 


This blog puts the spotlight on 5 hydrangea species that every gardener should be familiar with, offering some insights into their care and what you can expect from them in terms of aesthetics. 


General tips for growing most different species of hydrangea 

If considering growing any major hydrangea species, there are a few tips to keep in mind, such as: 


Hydrangea macrophylla

These are by far the most common form of hydrangea species, known for having large, round blooms and a variety of different subspecies or cultivars, including: 



This hydrangea species can clearly come in a wide variety of colours, which can be influenced by the soil pH it’s grown in – acidic for blue and alkaline for pinker shades. These flowers thrive with sun in the morning and shade once the afternoon comes around.


Hydrangea paniculata 

The paniculata umbrella of hydrangeas generally produces clusters of longer-lasting flower heads, rather than larger individual flower heads. It’s the base for multiple cultivars including: 



This hydrangea species tends to be a little more sun–tolerant than macrophylla, with flowers that will change in colour throughout the year. 


Hydrangea arborescens

This species of hydrangea is well-known for creating super round, thick clustered balls of flowers, with ‘Annabelle’ variations the most popular form, along with: 



They’re more hardy and adaptable than many forms of hydrangeas, tolerating shade and flowering for long stretches throughout the year.


Hydrangea quercifolia

These hydrangeas are notable for their impressive foliage; oak-shaped leaves that go a stunningly reddish bronze in the autumn months. They produce flowers somewhere in between macrophylla and paniculata – longer cones of larger-petaled flowers. Popular variants include: 



They like a reasonable amount of shade and need soil to be well drained to thrive.


Hydrangea aspera 

Known for the ‘Hot Chocolate’ variety, Hydrangea aspera plants have large, velvety, sometimes stunningly brown leaves, adorned with lacecap flowers and vibrant buds, usually in lighter pinks or lavender shades.


These are just some of the most popular hydrangea species, with there being many more out there, including climbing varieties and more. Understanding each species more clearly is the most effective way to guarantee a healthy, thriving garden (which is great for the head!)
