Availability: Out of Stock
The soft, light blue flowers of Cambridge Blue are perfect for any spot in the garden, hanging baskets, containers, window boxes, or borders. The pale green foliage is not often seen because of the profusion of flowers that bloom from spring to fall. In mild climates, lobelia will grow and bloom during the winter. Under ideal growing conditions, lobelia may reseed.

Loved how quickly the seeds germinated. Lobelia can be tough to plant, but this year it really shined

Don't know if it was the area or the seed, but as titled, nothing grew.

Owner Response: Hi Donna, Thank you for sharing your experience. We are sorry you had issued germinating this seed. We are always available to help troubleshoot germination and growing issues. When you say "area of the seed" it sounds like this was potentially sown outdoors which is Denver the soil would be too cold to allow seeds to germinate. Sowing recommendations are 1 to 2 weeks after your average last frost, which would be mid-May. Seeds can only germinate if the conditions are right and these particular seedlings would also be killed by frost. Rest assured our seeds are tested regularly by a third-party laboratory to ensure germination rates meet federal and our own standards. We are here to help, send an email or give us a call so we can help!
