Growing Sea Thrift
Sea Thrift or Armeria maritima is a slow-growing perennial that is worth the wait. This low-growing plant features rounded flower clusters that bloom on tall, thin stems. The flowers can be shades of pink, red, violet, or white. The blooms hover over narrow, pointy foliage that gives the plant a textured look. Enjoy the flowers from late spring through early summer, although the greenery stays in place year-round in warm climates. Armeria maritima is native to central and southern Europe and grows as a perennial in zones 4 through 8.
Planting Sea Thrift
Plant Sea Thrift in full to part sun. Morning sun and afternoon shade are preferred in southern regions. Sandy soil with low organic content is best for Sea Thrift. Overly rich soil can make the plant leggy and do more harm than good. This flowering perennial grows well in rock gardens and can handle a dry, wind-swept environment. Sea Thrift is salt tolerant and can easily live in coastal areas.
Watering Sea Thrift
Young plants need regular moisture to help them settle in. Established Sea Thrift plants are drought tolerant and can live in dry conditions. Water during an extended dry period or if the plant shows signs of dehydration, like drooping stems and wilted foliage.
Fertilizing Sea Thrift
Sea Thrift is not a heavy feeder and does best in low-quality soil. Fertilization is not necessary and can promote leggy plants.
Pruning Sea Thrift
Prune dead or damaged growth at any time. Remove faded flowers from Sea Thrift to promote sporadic reblooming. Tidy up the plant and remove any damaged growth in early to mid-spring before new growth appears.
Caring For Sea Thrift in Pots
Sea Thrift's clump-forming growth habit makes it an excellent container plant. Situate the container in a sunny spot and use sandy, well-draining soil. Depending on rainfall, potted Sea Thrift may need water as often as weekly, but monitor the soil, and water when the potting mix is dry.
Winter Care For Sea Thrift
Sea Thrift winter care is easy and minimal. Spread a thick layer of mulch to protect the roots from chilly winter weather. Sea Thrift often remains evergreen, especially in the warmer reaches of its growing range. Remove dead or damaged growth in the spring.
