Description

Armeria maritime is known by several common names, including common thrift and thrift seapink. It grows into a small mounding evergreen perennial growing 6-8 in. tall, 10-12 in. wide and has narrow dark green . Showy deep pink ball-shaped flowers develop on thin stems above foliage and are very attractive in mid to late spring.

In California, the common thrift grows on coastal bluffs sand dunes from San Luis Obispo County north to British Columbia, Canada. Throughout this range a number of local forms and variations exist that have led to different cultivars being available from local nurseries and garden centers. Flower colors range from magenta-pink to white.

Common thrift is a popular choice in Inland Empire gardens for border plantings, as a small area ground cover and for container use. It does best in partial shade and protection from afternoon sun and heat with regular water during summer.

Water Needs

The common thrift easily grows in Inland empire gardens when planted in areas that receive afternoon shade and when sustained with moderate amounts of summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water and you should make irrigation adjustments based of field observations of growth and character.

Maintenance

Cutting off faded flowers may extend bloom period, if desired, but is not necessary (5). This would be most effectively done with a manual hedge shear, as it would be too time consuming to remove flowers individually with a pruner.
