LOBELIA
These plants make great additions in borders, along streams or ponds, as ground covers, or in containers—especially hanging baskets. Lobelia typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil.
Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however, especially those in containers. A general-purpose liquid fertilizer can be given once a month or every 4-6 weeks, if desired.
