L. speciosa ‘Starship Blue’ has deep, violet-blue flowers produced on incredibly upright flower spikes set against bright green foliage, which remains green until frost.
The perfect plant for damp locations such as near ponds or low-lying areas. Will easily adapt to ‘wet feet’ but can also tolerate well-drained soils. L. speciosa is more adaptable than other Lobelias to various soil types and moisture levels. If enough moisture is available, it will thrive in the sun. In drier soils, it should be planted in part shade. Deadheading spent blooms will improve the overall appearance of the plant and may promote reblooming. It’s a good idea to cut this plant back in the spring instead of the fall, since the foliage will help protect the root zone in the winter. Mulch is also recommended.

According to Rutgers University, Lobelia are “seldom severely damaged” by deer.
