What Are Dwarf Hydrangeas?

When many of us think of hydrangea shrubs we think of larger shrubs covered in big pillowy flowers. These shrubs are amazing if you have the space in your garden.

However, if this isn’t the case or if you have a smaller yard or only a small amount of space that you are able to devote to a hydrangea than a dwarf variety is exactly what you need.

Many of these varieties have the same attributes as their larger counterparts, they just come in a shrunken down version. Many of these shrubs will top out at three feet high, making them a great choice for a low hedge, or an addition to a foundation or perennial garden.

When it comes to maintaining these dwarf hydrangeas their care is the same as it would be with the larger varieties. There is no special pruning required. In fact, the same old wood vs. new wood pruning rules applies to these little guys.
