Santolina, commonly called lavender cotton or gray santolina, is a small, evergreen shrub valued for its attractive foliage and ease of care. Here are its characteristics:

• Appearance: Santolina is a small shrub typically growing 2 feet tall and 3 feet wide. It has a mounding growth habit with dense, finely textured, silver-gray foliage. The leaves are pinnately divided, meaning they have leaflets arranged on either side of a central stalk, and have a rough texture and a musky fragrance.
• Flowers: Santolina blooms in summer with bright yellow, button-like flowers that rise above the foliage on 6-inch stalks. However, frequent trimming or shearing can prevent flowering.
• Climate: Santolina is native to the Mediterranean region and is well-suited for hot, dry climates. It is drought tolerant and can withstand cold temperatures down to 0°F.
• Sun: Santolina prefers full sun to part shade.
• Soil: It prefers well-drained, sandy soil.
• Care: Santolina is a low-maintenance plant that requires little watering once established. It benefits from light pruning after flowering to maintain its shape and encourage bushier growth.

Uses: Santolina is a versatile plant that can be used in various landscaping applications. It is an excellent choice for edging walkways and borders, creating low hedges, or as a groundcover. It can also be grown in containers. The dried leaves can be used in potpourris and dried arrangements.

Planting santolina is a breeze! Here's a guide:

Choosing the right spot:

• Sun: Aim for a location receiving plenty of sunlight, ideally full sun. They'll tolerate some part shade but may flower less.
• Soil: Well-draining soil is crucial. If your soil is heavy clay, amend it with sand or gravel to improve drainage. Santolina thrives in poor soil and even rocky areas.

Planting:

• Timing: Early spring is the ideal time to plant santolina, allowing it to establish roots before the summer heat. You can plant them throughout the year in frost-free regions, but spring offers the best chance of success.
• Spacing: Consider the mature size of the santolina variety you choose. Space them appropriately, typically 18-24 inches apart for individual plants or following the recommended spacing for hedges.

Planting steps:

1. Dig a hole slightly larger than the plant's root ball.
2. If your soil is heavy clay, amend the planting hole with sand or gravel to improve drainage.
3. Gently remove the santolina from its pot, teasing apart any compacted roots.
4. Place the santolina in the hole, ensuring it sits level with the surrounding soil.
5. Backfill the hole with soil, tamping it down gently to remove air pockets.
6. Water the plant thoroughly to settle the soil.

Aftercare:

• Water regularly, especially during the first year after planting, until the santolina is established. Once established, they are drought tolerant and require minimal watering.
• Apply a light layer of mulch around the base of the plant to retain moisture and suppress weeds.
• Santolina benefits from light pruning after flowering to maintain its shape and encourage bushier growth. You can also prune for shaping purposes throughout the growing season.

With proper planting and minimal care, your santolina will thrive and add a beautiful touch of silvery-gray foliage to your landscape.

There are several varieties of Santolina, but the most commonly grown ones are:

• Lavender Cotton (Santolina chamaecyparissus): Also called cotton lavender, this is a popular choice with needle-like, silvery-gray foliage and a dense, mounding growth habit. It typically grows 15-50 cm tall and produces bright yellow button flowers in summer.
• Green Santolina (Santolina virens 'Lemon Fizz'): This variety has a brighter green foliage compared to the classic gray santolina. It also grows slightly taller, reaching 25-60 cm in height. It has a bushier growth habit and produces small, light yellow flower heads between May and June.
• Santolina neapolitana: This variety differs more significantly from the other two. It has a more upright, shrub-like form and grows taller, reaching 2-3 feet tall and wide. It also has slightly wider, lobed foliage and produces clusters of soft yellow flowers in spring.

These are just a few of the many santolina varieties available. With their diverse foliage colors and growth habits, there's sure to be a santolina perfect for your garden.

Here's how to care for your santolina and keep it thriving:

Watering:

• Young plants: Water regularly during the first year, especially during hot and dry periods, to help them establish a strong root system.
• Established plants: Santolina is drought-tolerant once established. Avoid overwatering, as this can lead to root rot. Water deeply when the soil feels dry to the touch, typically every few weeks during summer and even less frequently in cooler months.

Sun:

• Santolina thrives in full sun locations, receiving at least 6-8 hours of direct sunlight daily.
• They can tolerate some part shade, but flowering might be reduced.

Soil:

• Well-draining soil is essential for santolina's health. They prefer sandy or rocky soil but can adapt to average garden soil as long as drainage is adequate.
• If your soil is heavy clay, amend the planting hole with sand or gravel to improve drainage before planting.

Fertilizing:

• Santolina generally doesn't require fertilizing. Excessive fertilizer can promote leggy growth and reduce flowering.

Pruning:

• Light pruning after flowering (typically summer) helps maintain a compact shape and encourages bushier growth. You can also prune for shaping purposes throughout the growing season.
• For established santolina that has become leggy or overgrown, a more drastic pruning in late winter or early spring is beneficial. Cut back the stems by one-third to half their size to rejuvenate the plant.

Other care tips:

• Deadheading spent flowers throughout the blooming period can encourage reblooming.
• Santolina is generally pest and disease resistant. However, in humid conditions, fungal diseases can occur. Ensure good air circulation around the plant and avoid overwatering to prevent this.

By following these simple care tips, your santolina will reward you with beautiful silvery-gray foliage for many years to come.

Santolina does attract pollinators, particularly bees and butterflies! Here's why:

• Blooming flowers: Santolina produces small, bright yellow button flowers in summer. These flowers offer nectar, a sugary substance that attracts pollinators like bees, butterflies, and even some hummingbirds.
• Fragrance: While the foliage has a somewhat musky scent, the flowers have a subtle, honey-like fragrance that can also be attractive to pollinators.

While Santolina might not be the most flamboyant flowering plant, its blooms and subtle fragrance are enough to entice pollinators to visit. This can contribute to a healthy and vibrant garden ecosystem.

Here are some additional points to consider:

• Flowering frequency: Frequent trimming or shearing can reduce flowering, thus potentially reducing the number of pollinators attracted.
• Habitat provision: Santolina's dense foliage can provide some shelter for beneficial insects like ladybugs and lacewings.

Overall, Santolina is a pollinator-friendly plant, and incorporating it into your garden can support a variety of pollinating insects.

Santolina is fortunately quite resistant to pests and diseases! However, there are a few potential issues to keep an eye on, especially if growing conditions aren't ideal.

Pests:

• Whiteflies and spider mites: These are occasional visitors and are more likely to appear in hot, dry weather. You can usually control them with insecticidal soap sprays or by introducing natural predators like ladybugs.

Diseases:

• Fungal diseases: Fungal diseases like root rot and Botrytis (gray mold) can occur if santolina is planted in poorly drained soil or receives excessive moisture.

Here's how to prevent these issues:

• Provide good drainage: Ensure your santolina is planted in well-draining soil and avoid overwatering.
• Air circulation: Good air circulation around the plant helps prevent fungal diseases. Avoid overcrowding santolina with other plants.
• Watering practices: Water deeply but infrequently, allowing the soil to dry out somewhat between waterings.

If you notice signs of pests or diseases, early intervention is key. For minor infestations, neem oil spray or insecticidal soap can be effective. For severe cases, consult your local nursery for advice on appropriate treatment options.

By following these tips, you can help your santolina stay healthy and pest-free.
