Limonium or Sea Lavender for endless beauty and aroma in your garden
Limonium, also known as Sea Lavender, is a genus of about 120 species in the family Plumbaginaceae, native to the Mediterranean region and central Asia.
Limonium is a tall plant with a cluster of small flowers sitting atop sturdy stems. It comes in a wonderful range of colors and is easy to maintain. The flowers are widely used in fresh and dried flower arrangements, but are also beautiful in the garden.
How to Grow Sea Lavender Plants
Sea lavender is an ideal choice for gardeners who want to create bold, lasting color in hot or dry climates. They are a great addition to flowerbeds, borders, and cutting gardens, as well as for larger patio containers and fresh or dried arrangements.
Better yet, sea lavender is a fairly easy perennial to cultivate and has very few cultural needs. It can be divided every two or three years (always in early spring), but be sure to dig deeply to prevent damage to its long roots. Sea lavender is often considered difficult to divide, and taller plants may require stakes in order to remain upright.
These plants attract pollinators including bees and butterflies. Though they are considered virtually pest- and disease-free, some of the issues these plants could be susceptible to are: rust, leaf and flower spots, gray mold, crown rot, and Southern blight. The flowers will typically turn brown in the winter months.
Sea lavender will grow best when planted in full sun, as it will encourage the largest amount of densely grown flowers. Additionally, planting in full sun will also help to ensure the plant stays dry, which can help prevent root rot.
You’ll want to water newly-planted sea lavender regularly in order to establish a deep and healthy root system. However, once the plant is established, it will only require occasional watering. Sea lavender is a drought-tolerant plant.
Sea lavender thrives in sandy soil, but will tolerate average, well-drained soil.
Temperature and Humidity
A warm-weather plant, Sea lavender will flower throughout the summer, but reaches peak flowering around August and September. As a coastal perennial, it will grow well in salty, sandy, and windy conditions.
Take care when using fertilizer with sea lavender, as fertilizing too heavily may cause it to grow excess foliage and never actually flower. It can also kill these plants. When looking for fertilizer, steer clear of varieties that are rich in nitrogen.
Potting and Repotting
If you’re considering potting sea lavender, choose a sandy, alkaline, and well-draining potting mix, preferably without added fertilizer.
