    True blue flowers can be difficult to find in nature but Lobelia are true, real blue. This lobelia has better heat tolerance than older varieties.

    Maintenance Notes: 

    Self cleaning, no deadheading necessary. Laguna does not like "wet feet". Be sure that you do not keep the soil wet. Allow the soil surface to dry before watering again.

    These newer types of Lobelia are much more heat tolerant than past plants. They will reliably bloom in warm temperatures unless night temperatures stay in the upper 70's or above. If you experience an extended time period with high night temperatures the plants may flush out of bloom, however, the plants themselves should continue to look good. If the plants do go out of flower using a sharp pair of scissors or pruning shears to give the plants a "haircut" - a slight overall trim - should encourage additional branching. Additional branching will result in increased flower power once the plants begin blooming again after night temperatures fall.

    The plants may be trimmed back at anytime if you feel they could use it.

    A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

    Lucia® lobelias are bred to handle the summer heat better than most, delivering good all-season performance in landscapes, hanging baskets, window boxes, and combination containers. Choose from deep blue or vivid royal purple, self-cleaning selections when you buy.

    • It was stunning while it bloomed. Then in early summer both my blue and white varieties just started dying a little at a time. So disappointed! Maybe it was too hot and humid for them...? I wish that these plants came with more detailed instructions. The blue is so unusual and beautiful; I might have to try again next Spring, but will call the company for help the minute things start going downhill.

    • I bought this plant twice this year. I gave one to my sister because it had the name of her daughter Lucia who died at age 6. Unfortunately both hers & my plants died.

    • I live in Prescott Valley, AZ, which is a cooler area than Phoenix. I bought several of these last summer and they all died as rapidly as regular lobelia.
