Delphiniums are a beautiful tall flowering plant that really makes a beautiful statement in a garden. Delphiniums go well with many other plants including Iris, Sunflowers, Hollyhock, Foxglove and others. Delphiniums are tall and do best if they are staked so that they do not topple over in wind or rain. Delphiniums grow about 2 to 6 feet tall and come in various colors such as white, purple and pink.
Key Takeaways:
- Depending on variety, delphinium plants can grow 2- to 6-feet tall and 1- to 2-feet wide. Oftentimes, tall delphiniums will need staking or some kind of support, as they can get beaten down by heavy rains or wind.
- When companion planting with delphinium, you have many options, and what to plant next to delphiniums is completely up to you.
- Delphiniums are deer resistant, and though Japanese beetles are attracted to the plants, they reportedly die from eating toxins from within them.
“No cottage garden is complete without graceful delphiniums standing tall in the background. Delphinium, hollyhock or mammoth sunflowers are the most common plants used for back borders of flowerbeds or grown along fences.”
