The plant has a compact, rounded shape, reaching a height of about 60 centimeters and a similar spread. Santolina crithmifolia L. is evergreen and has many small, linear grey-green leaves which give off a strong lemon scent when crushed. The plant also produces tiny yellow button-like flowers that bloom in late summer on short stalks above the foliage.
Uses
Santolina crithmifolia L. has a variety of uses. The leaves and flowers have been used for centuries in traditional medicine as a natural remedy for digestive issues, coughs, and colds. The essential oil derived from the plant has antibacterial and antifungal properties. Its strong lemon scent has also led to use in the cosmetic industry, including the creation of perfumes and aromatic oils.

Furthermore, Green Santolina has been used to make insecticides to repel ticks, fleas and dust mites.
As it is resistant to drought, Santolina crithmifolia L. can be a great partner if you prefer to plant species that require little maintenance.
Cultivation
Santolina crithmifolia L. prefers dry, well-drained soil and full sunlight, though it can tolerate partial shade. In terms of soil, make sure it is well-drained, sandy, and dry. This plant is highly drought tolerant, so be careful not to overwater. During the summer, it is advisable to prune the plant to maintain its compact shape.
Propagation can be done by seed sown in the spring or through stem cuttings taken in early summer or fall. When transplanting, make sure to plant the young shrubs approximately 45 centimeters apart to provide enough space for growth.
If you enjoy low-maintenance yet beautiful plants in your garden or on your balcony, Santolina crithmifolia L. could be an excellent addition. It's hardy, easy to care for, and has numerous uses beyond just being an ornamental plant.
Light Requirements
Santolina crithmifolia L. thrives in full sunlight. It requires at least 6 hours of direct sunlight every day to grow healthy and produce flowers. Gardeners should plant Santolina crithmifolia L. in a location that receives full sunlight, preferably with minimal shade or interruption.
Temperature Requirements
Santolina crithmifolia L. prefers temperate to warm climatic conditions, meaning that the average temperature range should be between 10°C to 30°C. The plant can tolerate frost and temperatures as low as -5°C. Prolonged exposure to freezing temperatures can stunt growth and damage the plant.
Soil Requirements
Santolina crithmifolia L. requires well-draining soil and is tolerant of drought. The plant prefers a soil pH between 6.5 and 7.5. Gardeners can add organic matter such as compost to improve soil quality. Santolina crithmifolia L. can grow in rocky, poor-quality soil, as long as it is well-draining and not waterlogged.
Cultivation Methods
Santolina crithmifolia, commonly known as Lavender Cotton, is a bushy evergreen shrub that is relatively easy to grow. It can be grown in containers or directly in the ground. When planting in the ground, it is best to choose a well-draining location that is not prone to waterlogging. This plant is also tolerant of poor soils, but it is best to add some compost or well-rotted manure to the planting hole.
Watering Needs
When it comes to watering, Santolina crithmifolia prefers dry conditions. Overwatering can lead to root rot, which can be fatal for the plant. It is best to water the plant deeply but infrequently. During the hot summer months, it may require watering once a week, but during the cooler months, it can go for several weeks without water.
Fertilization
Santolina crithmifolia does not require a lot of fertilization. In fact, too much fertilizer can result in leggy growth and fewer flowers. A balanced all-purpose fertilizer can be applied in the spring, but it is not necessary. Adding compost or well-rotted manure to the planting hole can provide enough nutrients for the plant.
Pruning
Pruning is not necessary for the health of Santolina crithmifolia, but it can help keep the plant looking tidy and encourage bushier growth. The best time to prune is in late winter or early spring before new growth begins. Prune back about one-third of the previous year's growth, making cuts just above a leaf node. Avoid pruning too much, as it can reduce the number of flowers the plant produces.
Propagation of Santolina crithmifolia L.
Santolina crithmifolia L., commonly known as cotton lavender, is a beautiful plant that belongs to the Asteraceae family and is native to the Mediterranean regions. This plant is grown for its attractive gray-green foliage and yellow button-like flowers that bloom in summer. Santolina crithmifolia L. is a low-maintenance plant that is easy to propagate through several methods.
Method 1: Seed propagation
Santolina crithmifolia L. can be propagated by seeds, which are readily available in local nurseries. The best time to sow seeds is in early spring after the last frost. Fill a seed tray with well-draining soil and scatter the seeds on top. Cover the seeds with a thin layer of soil and mist with water. Germination usually occurs within 10-14 days. After germination, thin out the seedlings, leaving only the healthiest ones to grow. Transplant the seedlings into larger pots or outdoors in well-draining soil with full sun exposure.
Method 2: Cuttings propagation
Another way to propagate Santolina crithmifolia L. is through cuttings. Take stem cuttings from the plant in late spring or early summer. Choose a healthy stem that is not flowering and cut it about 4-6 inches long. Dip the cut end of the stem into rooting hormone and insert it into a pot filled with well-draining soil. Water the cuttings well and place them in bright, indirect light. After a few weeks, the cuttings should start to root. Once the cuttings have rooted, transplant them into larger pots or outdoors in well-draining soil with full sun exposure.
Method 3: Division
Santolina crithmifolia L. can also be propagated through division. The best time to divide the plant is in early spring. Carefully dig up the plant and separate the clumps into smaller sections with a sharp knife or spade. Make sure that each section has sufficient roots and foliage. Plant the divided sections in well-draining soil with full sun exposure. Water the newly divided plants thoroughly and keep them well-watered until they are established.
Propagation of Santolina crithmifolia L. is easy and rewarding. With proper care and maintenance, the plant will thrive and provide beauty in any garden or landscape.
Disease Management for Santolina crithmifolia L.
Santolina crithmifolia L. is generally a hardy plant and not highly prone to diseases. However, some fungal infections may occur, causing leaf spots and discoloration. Overwatering and humid conditions can encourage fungal growth. Prevention of fungal diseases is the best method of management. It can be achieved by not overwatering, ensuring adequate drainage, and pruning to create proper air circulation. Fungal diseases can be treated using fungicides such as copper-based compounds or neem oil.
Pest Management for Santolina crithmifolia L.
Santolina crithmifolia L. may not be prone to pest infestation, but some pests may still pose a problem. Common pests that affect the plant include spider mites and aphids.
Spider mites can be detected by the presence of webbing and small yellow spots on the leaves. They suck sap from the plant resulting in leaf discoloration and stunted growth. Spider mites can be managed by spraying the plant thoroughly with water. In severe cases, neem oil or other insecticidal sprays can be used.
Aphids are tiny, pear-shaped insects that are usually green, yellow, or brown. They congregate in large numbers on the underside of leaves, where they suck sap from the plant. This results in distorted growth and stunted development. Aphids can be managed by applying insecticidal soap or neem oil. Predatory insects such as ladybugs can also be introduced to control aphids naturally.
