Grow this every year and bring it inside before the first frost. It will survive another winter though not as pretty as the first. I love having the flowers in the winter. Relieves that winter groggy feeling!
EGEpic GardeningNov 13, 2023Hey Linda, Thank you very much for sharing the photo of your Lobelia. I'm so glad it's bringing you many seasons of joy, especially during the winter months! Keep on growing 🌻️

I believe I planted them too late.

Thank you so much for your review! The best time to plant Cambridge Blue Lobelia seeds outdoors in your area is about one to two weeks after your average last frost date, which typically falls around April 11. This means mid to late April, or even early May depending on the spring weather, is generally a good time to sow them directly outside. If you’d like to get a head start, you can begin seeds indoors about 8 to 10 weeks before the last frost and then transplant them once the danger of frost has passed. This helps ensure strong, healthy plants that will thrive through the season. I hope that helps. Please feel free to reach out o us with any questions, or check our blog, www.epicgardening.com, or YouTube for more hints and tips. We're happy to help!

Germination was very good however most the flowers were Blue, a few scattered white, and barley any other color. Not a good mix of colors. Would not buy again

- JulieVerified ReviewerRated 3 out of 5 starsJul 26, 2025Pretty but only blue
I bought these as I wanted the mixed colors and unfortunately, they are all blue. I sprinkle when I start seeds indoors and have six different bunches of plants throughout my garden beds so I know the packet is just blue - and that is the only reason why they lost two stars. They germinated fabulously and they are holding up in the hot sun and even if I miss a day or two or watering, they bounce right back.

Thank you so much for taking the time to share your thoughts in a review. 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.
