We transplanted a couple of very large hydrangeas and plan to plant some little giant arborvitae in their place. The hydrangeas left behind quite a large and expansive root system. Will these roots grow new hydrangeas and invade the new plants? How thorough do we need to be about making sure every root is dug up and removed?

Hydrangea grow from the crowns of the plant, never runners. They won't come back if you removed the crown.

Sort of. Smooth hydrangea (the Annabelle-like hydrangea, also called hydrangea arborescens) sometimes propagates from suckers like a Crape Myrtle. This makes the original single planting get wider and wider and wider... can be a pain sometimes.

I am curious how old and large this large hydrangea was. And if you took a picture of the root system that you found, would you mind posting a picture? Just curious so no problem if you did not take pics. Thanks in advance.

I stand corrected, Luis is correct. I defaulted to big leaf hydrangea (the bushes that grow about 3-4 ft tall, traditionally with very round blueish flowers. although now they come in many different shades) and forgot about other varieties
