I just bought a package of Larkspur flower seeds. I live in Zone 8. Very sunny and hot location in summer. Where is the best location to plant them? Thank you
You will just have to make sure to plant these annuals when the temperatures are below 65 degrees. They won't germinate in the heat. This article will give you more information: https://www.gardeningknowhow.com/ornamental/flowers/larkspur/growing-annual-larkspur-plants.htm
Hi, I am wondering if you may know what is the name of the flower in cyan(blue) in the attachment? Thank you. Lam
It is a delphinium of some type.

Can you offer me any suggestions as to which varieties would do well here in the fall and winter? We don't have any freezing weather usually until mid-January. Thank you.
You will want to sow these in later winter, when it is still cold, but will warm up soon. They will not tolerate much heat, so it will be best to plant somewhere that gets morning sun, but has shade during the hotter parts of the day.

Can not find the above answer on your web site. Should delphiniums be planted in the the dark if I am trying to plant/germinate seeds in the House ?
Place the delphinium seeds on the surface of the compost, spacing them one inch apart. Cover them with a 1/4-inch-thick layer of seed-starting compost. Mist it with water and gently firm the surface.
Place the seed tray outdoors in a sheltered, lightly shaded garden area where temperatures stay between 65 and 75 degrees Fahrenheit during the day. Provide warmth with a propagation mat if the weather is unusually cool.
Maintain a light level of constant moisture in the top 1 inch of compost while the delphinium seeds germinate. Let the surface dry slightly between waterings to keep the seeds from rotting.

My beautiful delphinium didn’t come back this year! It is 4 years old and has presented gorgeous blooms each year. This year it didn’t return. Any ideas?
Delphiniums can be a challenge; not all grow as perennials. Many are short-lived plants. Optimize the growing conditions as explained in the articles below.

My Delphiniums were huge and gorgeous but this year they didn't get any taller than 12-18 inches tall. Some of them flowered with deformed looking blooms and containing more of a greenish tint than their original beautiful colors. I don't know what to do or what is going on with them. HELP!!
If you have fed them this year, then it is likely that the feed contained too much nitrogen. If you have not fed them, then I would be looking to phosphorus and potassium deficiencies.
They are also particular about the pH of their soil. This should be neutral to slightly alkaline. Acidic soil will lock out phosphorus and potassium to the plant.
Alternatively, if you are also noticing brown spotting, then it could be a fungal infection.
