Sea Lavender: A Coastal Gem
Introduction
Sea lavender, also known as marsh rosemary or lavender thrift, is a unique and beautiful perennial plant that thrives in coastal environments. Despite its name, it has no relation to lavender, rosemary, or thrift.
Characteristics and Habitat
Sea lavender (Limonium carolinianum) is a hardy plant with red-tinted stems and leathery, spoon-shaped leaves. It produces delicate purple blooms in the summer months. It is commonly found growing wild in salt marshes and along coastal sand dunes.
Importance of Conservation
Sea lavender is an important coastal plant that provides food and shelter for wildlife. However, its habitat is threatened by development and overharvesting. It is protected by federal, local, or state laws in many areas.
Growing Sea Lavender
Growing sea lavender is possible in USDA plant hardiness zones 3 through 9. It prefers full sunlight in most areas, but benefits from afternoon shade in hotter climates. It tolerates average, well-drained soil, but thrives in sandy soil.
Care and Maintenance
Water new sea lavender plants regularly to establish a deep root system. Once established, it is drought tolerant and requires only occasional watering. Divide sea lavender every two to three years in early spring, digging deeply to avoid damaging its long roots. Remove dead leaves in spring to make room for new growth.
Limonium Plants as a Substitute
If you are unable to grow sea lavender in your area, consider using Limonium plants as a substitute. They are related to sea lavender and may even share its common name.
Tips for Optimal Growth
- Choose a planting site that receives full sunlight or afternoon shade.
- Plant in well-drained soil, preferably sandy soil.
- Water new plants regularly until established, then reduce watering frequency.
- Divide sea lavender every few years to promote healthy growth.
- Remove dead leaves in spring to encourage new growth.
Protecting Coastal Plants
It is important to protect coastal plants like sea lavender from overharvesting and habitat destruction. Avoid picking its flowers, as this prevents it from expanding and forming colonies. Never remove the entire plant by the roots, as this will destroy it.
