I've been dealing with some groundwater flooding in my garden and want to tackle the problem by planting some very thirsty plants, shrubs, or trees. The key is that I need options that won't harm my house's foundations, pipes, or culverts with their root systems. We already have a birch tree at the bottom of the garden, and while I suspect it might be contributing to the flooding, it's a stretch since we lived here for eight years without issues. What are some good plant choices that can help soak up excess water?

Alder trees or hedges thrive in wet ground. I’ve got one in clay soil that does well even when soaked during winter. They can grow quite big, but you can coppice them if they take up too much space in your garden.
If you have shady areas, definitely consider astilbe! They love wet ground and come back each year as perennials. Plus, they're really attractive!
Consider Guelder rose if you want a bigger shrub. They love damp conditions and have pretty flowers, tasty berries, and nice autumn colors, plus they’re native!
Hydrangeas are wonderful for damp spots! They're one of my favorites for adding color and they thrive in wet conditions. Perfect for your needs!
Any excuse for a hydrangea for me. Thanks!
More like Hydrate-gea ?!
If you're looking for thirsty plants, I'd recommend the arum lily! It's great at soaking up water and won't damage your foundations. Just a heads up, it can be a bit toxic to pets, but I've had mine for decades without any issues. Other solid choices are pulmonaria, heuchera, hydrangea, and various ferns—basically, anything that loves damp or shady spots. But steer clear of running bamboos; they can cause trouble with their roots. Clumping varieties are more manageable though!
Our pets don’t go in the garden so arum might still be on the cards. Another vote for hydrangea is good, I love 'em. Fantastic suggestions, thank you!
I love hydrangeas, so this is a goer for sure. And part of the area is very shady, so I'm loving the idea of astilbe—it’s so pretty. Thank you!
