Growing & Maintenance Tips for Lobelia cardinalis
The perfect plant for damp locations such as near ponds or low-lying areas, Lobelia will easily adapt to 'wet feet' but can also tolerate well-drained soils. If enough moisture is available, it will grow in full 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.
