    My rocket larkspur turns out great. They are tall and radiant with beautiful flowers. It truly bring a great pop of color to my first year garden.

    I don’t understand. I bought a small packet of these last year and they flourished. I loved them. So I decided to buy 2 ounces this year and not a single sprout.

    Store owner replied: Hello Cassie Hensley. Thank you for your review. We are sorry to hear that you didn't have the same success with this larkspur mix that you enjoyed last year. We understand how disappointing it is to see a variety flourish one season and then fail to germinate the next. Larkspur can be quite sensitive to growing conditions, and even small differences in weather from year to year can have a significant impact on germination. Warmer soil temperatures, excessive rainfall, fluctuating moisture levels, or an unseasonably warm period after planting can all reduce germination success. In Zone 8, larkspur generally performs best when sown in fall or very early spring during cooler conditions. We reached out and offered a resolution, but if you haven't had a chance to respond, please feel free to reply to that email. We are always happy to help and stand behind our products. Thank you for your feedback, and we'd love the opportunity to assist you further!

    These were a show stopper in the garden well into summer. Brought all the pollinators, color, and texture to the garden I needed. Can't wait till I plant more this spring.

    These are the best Larkspur I've had. They were blooming at the same time that my Delphiniums were, right next to them. They were as spectacular together. After the first bloom of my Delphiniums, the Larkspur kept right on blooming, and still are now, in the middle of September. They are now almost 6ft. tall. Loved them last year and so glad to have ordered them this year.

    Read the reviews before buying these seeds. I’m a seasoned gardener and these were clearly defective or sterile.
