Product Details

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.

    The seed quality is fabulous! I had 100% germination with little to no effort. My only complaint is that the seed packs aren't self sealing like most other seed companies.

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