Some blooms
need space to
spread.
Experts say these flowers fail in
containers,
avoid them for a healthy garden.
1. Black-Eyed Susan
Spreads fast, roots run deep, and pots cause mildew. Better in open soil.
2. Joe Pye Weed
Grows tall and thirsty. Pots dry too quickly and topple easily.
3. Coneflower
Roots get cramped in containers. Stress from uneven watering weakens them.
4. Milkweed
Deep taproots hate being confined. Needs ground space to thrive.
5. Bee Balm
Spreads aggressively and gets mildew in pots. Too crowded for containers.
6. Hollyhock
Reaches 6–8 feet tall. Pots can’t support their height or prevent rust.
7. Delphinium
Tall with deep roots. Needs steady moisture and strong soil support.
