How to Care for the Plant

Water
Keep plants evenly moist until established. Once mature, these plants have average water needs, but will readily tolerate short periods of drought. Many of the parent species of these hybrids are native to Mediterranean regions or dry prairies, and their water needs resemble the conditions of those regions.
Fertilizer
Verbenas are not heavy feeders, but they do appreciate a monthly application of balanced, slow-release flower fertilizer to help them keep up the flower show, which can last from spring until frost.
Sunlight
Plant verbena in full sun. Flowering will be much reduced in shady locations. This is a plant that requires 8 to 10 hours of sun daily.

Temperature
Planted as annuals hybrid verbenas perform suitably in virtually any climate, but may decline in the hottest period of the summer.
