    Hi! First, I would not mention this experience to anyone. The pound of wildflowers were entirely green foliage with a few tiny flowers. The sunflowers, cosmos, dill and basil produced nothing. Parsley was the only one that did. I will plant trees next year. Thank You.

    Store owner replied: Hello Christine O. Thank you for sharing your experience with us. Many perennial flowers naturally take longer to establish. They often focus on root growth their first season with fuller results appearing the following year. The All Perennial Wildflower Mix especially is designed for long-term displays, so limited blooms in year one are completely normal. With a little patience and the right care, you should see much stronger growth and color in seasons to come. After speaking with our Customer Service Team, it seems we were able to assist you with this and the others mentioned, from your orders. Thanks for your time in sharing your experience with us and please reach out to us for help if needed!
