The oldest name for the plant is Palmerella debilis, coined by Asa Gray in 1876. Greene in 1889 wanted to move the species to the genus Lobelia, but could not use the name Lobelia debilis, because that name had already been used for a different plant by Linnaeus f. in 1782. Hence Greene created the replacement name Lobelia dunnii. More recent publications favor reverting to Gray's older name.

Water:
Native to arid regions, palmerella debilis is drought-tolerant, requiring weekly watering. It thrives in full sun and is ideal for outdoor cultivation. Its adaptability to low-water environments makes palmerella debilis a great choice for xeriscaping in drought-prone climate zones.
Fertilize:
Nurture palmerella debilis with a balanced fertilizer monthly during the growing season for robust growth and enhanced flowering. Use a phosphate-rich formula at half-strength, and moisten soil prior to application to prevent root burn. Reduce frequency in dormancy to avoid over-fertilization and ensure plant health.
Pruning:
Pruning palmerella debilis is essential for maintaining shape and promoting growth, ideally done from early to late spring. Key techniques involve removing dead stems and thinning dense areas for better airflow. This practice not only improves aesthetics but also prevents disease and enhances flowering.
Propagation:
Palmerella debilis can be propagated via cuttings from a healthy, disease-free section with at least two leaves or nodes. Plant the cutting in well-draining soil, maintain moderate moisture, provide indirect light, and ensure high humidity to promote successful root development.
