I personally don’t like this flower, they are small and only one color. Easy to grow though.
Which best describes you as a gardener? IntermediateBIBotanical Interests7/25/25Hey Grace,
Thank you so much for taking the time to share your thoughts in a review and for the photo. A flower might not bloom in the color you were expecting for several natural reasons, and it doesn’t necessarily mean something is wrong. Soil conditions can play a role; certain flowers, like hydrangeas, change color based on soil pH and mineral content. Weather and temperature fluctuations, such as heatwaves or cold snaps, can impact pigment development and lead to muted or altered flower colors. Your feedback is invaluable to us, and we are committed to ensuring your experience is positive. Please feel free to reach out to our customer service team if you have any questions. We're happy to help. Thank you once again for your input. Keep on growing 🌻️

I have tried to start these seeds three times and they will not germinate. So far, I have one tiny sprout out of the whole packet of seeds. I am very satisfied with my other purchases from BI but this one is a dud.

I was not successful with these. But rain probably interfered.
