Here's a quick list of long lived perennials that will thrive in the garden for many years:
- Peony (some live to be 100!)
- Hosta (shade)
- Oriental Poppy
- Catmint (benefits from a good trim two to three times a summer)
- Trumpet Vine
- Moss Phlox
- Baptisia (also called Blue False Indigo). Shown in photo above.
Most of these plants have such longevity because they are naturally drought- and insect-resistant.
