Agalinis maritima

Saltmarsh false foxglove comes from bright, open habitats and thrives in full sun. It will tolerate partial sun, but direct sunlight is preferred for best growth. This plant, which can be annual or biennial, is known for its sun-loving character.

Saltmarsh false foxglove can tolerate a wide variety of temperatures, but its range may still be restricted by different combinations of moisture and heat. It performs best in warm summer climates with sufficient rainfall or watering. Long periods of cloudy, rainy weather or extended high temperatures can increase the chance of Saltmarsh false foxglove dying. In winter, adequate protection from the cold can raise the plant's survival rate.

When most of the Saltmarsh false foxglove's flowers have opened to full size, resume fertilizing. At the time the blooms are at peak output, apply fertilizer every three to four weeks, depending on the weather. Then, once the Saltmarsh false foxglove begins producing fewer new blooms, stop fertilizing — there's no need to feed the plant when it can no longer produce additional blooms.

To encourage healthy growth and vibrant blooms in saltmarsh false foxglove, it's beneficial to thin the plant annually. This helps improve airflow and light exposure. Prune the plant from early to late spring to shape it and minimize the risk of disease. Pay particular attention to removing weak or crossing branches to enhance both the plant's vitality and its appearance.
