Delphiniums are a popular summer flower plant known for their colorful spikes and long, colorful stems. They require full sun to partial shade, depending on the region. Choose an area with loamy, well-draining soil with a pH around 7, keeping it moist but not too wet. Ensure the soil has afternoon shade as it does not do well in dry heat. Plant delphiniums in an area blocked from wind, as their tall stocks are susceptible to damage.
Delphiniums can be grown as annuals or perennials, depending on the species. To grow delphiniums, choose a location with moist but well-drained soil in full sun. Aid drainage by adding grit to the planting hole if heavy soil has heavy soil. Protect emerging shoots and sow seeds 1/8 inch deep, lightly covering them with soil. Keep slightly moist but don’t overwater.
Delphiniums need a minimum of six hours of sun a day, with afternoon shade in hot climates. They prefer well-draining soil rich in organic matter and consistent moisture, especially during the growing season. Delphiniums grow best in sunny positions with well-drained soil that is slightly acidic.
To ensure proper care, mulch helps retain moisture and keeps roots cool. Choose a site in full sun or dappled shade and add grit to heavy soils to help with drainage.

I gave your article thumbs down All your tips are rather “surprising” Because A: no matter what, you can’t grow them at all unless you deter sluggzzzz Every delphinium grower knows that. B: Goes without saying that tall slender varieties need staking, However you didn’t mention sturdy shorter varieties !! C: I would expect a more accurate tip on fertilizer, from a vid sponsored so directly by a fertilizer company. .. At what growing stages ❓ what NPK ratio❓ do they benefit acid / base❓ Organic matter ❓ and even HOW MUCH PER PLANT 🌺🌺🌺👀❓❓ I’D love to see that vid re done .
I have a blue Pacific Giant delphinium that I planted in about 2015 – so 10 years old (holding my breath!) and about 5-6 feet tall. I am near Denver, Zone 5, cold winters, wind. I put 3 tomatoe cages around them – just added a fourth – which I attach to each other and to the fence. I intend to plant a few more since I’m not sure how much longer it will live. Love them!
I just found this article and I’m glad I did! Good to know that I wasn’t doing something wrong as to why the “perennial” ones I was buying at the big box stores weren’t coming back in my zone 5. The first one I bought did, but it didn’t make it due to rot. I wouldn’t buy the seeds because I thought they wouldn’t come back, but I will try next year or see if I can still find seeds and try to start now inside, and transplant in the fall.
I bought a delphinium a couple years ago and it comes back every year and blooms beautifully. Big gorgeous purple blooms. I have a question about what was said about cutting it back to about an inch above the ground after it blooms in hopes of getting a second bloom. If I do that won’t water get inside the plant? As the stems are big and hollow. So if it rained or water from the sprinkler got in the stem could that cause crown rot? I live in zone 5, SE Idaho.
