From seed to flower in one season. I have heavy clay soil and these did great. I'll be starting more seeds and gifting to friends. Zone 5b Michigan.

I grew Pacific Blues 20 years ago and I loved them. They were my late son’s favorite flower.
I was totally thrilled to see they bloomed the first year. It is now the 29th of September and I still have flowers blooming.

The colors on these flowers are unbelievable. Different shades of blue and purple, almost iridescent! I'm yet to see a Delphinium at the local nurseries that can compare in intensity of colors. This the first batch of seeds I planted last year and I'm glad I could salvage a couple of them! Now that I'm a more seasoned gardener, I will try again next year.

Way too early to give an overall review because seedlings are just an inch high. However, the germination was good. Put seeds on a damp paper towel in a zip lock bag in the refrigerator for one week before sowing and was happy with the germination.
