The silver bush, or Convolvulus cneorum, is a compact evergreen shrub prized for its silvery foliage and bright white flowers with yellow centers. It is ideal for sunny borders, coastal gardens, and containers. Learning proper Convolvulus cneorum care will help you keep this plant healthy and attractive year-round.

To start, plant it in full sun and well-draining soil. It thrives in sandy or gritty conditions and tolerates drought once established. Overwatering is one of the most common Convolvulus cneorum problems, often leading to root rot. Avoid heavy clay soils or waterlogged spots. In humid climates, ensure good air circulation to prevent fungal issues.

When considering how to grow Convolvulus cneorum, choose a sheltered location with maximum sunlight exposure. This plant performs best in USDA zones 8–10 but can survive in slightly cooler climates with winter protection. Water moderately during the growing season, allowing the soil to dry between waterings. During colder months, reduce watering to prevent excess moisture around the roots.

In landscape design, Convolvulus cneorum pairs beautifully with Lavandula angustifolia (English lavender). Both plants prefer full sun, excellent drainage, and low to moderate watering, making them naturally compatible. Lavender’s fragrant, purple flower spikes create a striking color contrast against the silver foliage of Convolvulus, while also attracting pollinators such as bees and butterflies to the garden.

Iberis sempervirens, commonly known as evergreen candytuft, is another excellent companion plant. This low-growing perennial produces clusters of crisp white flowers in spring that complement the silver bush’s foliage and blooms. Iberis sempervirens thrives in similar soil conditions and works well as a groundcover at the base of Convolvulus cneorum, helping to suppress weeds and soften the edges of garden beds.

Regular Convolvulus cneorum pruning keeps the shrub neat and encourages dense growth. Trim lightly after the main flowering period in summer to remove faded blooms and maintain shape. Avoid cutting into old wood, as this can reduce flowering the following season.

Feeding with a balanced, slow-release fertilizer in spring will promote healthy foliage and abundant blooms. In containers, use a well-draining potting mix and re-pot every few years to refresh the soil.

With the right approach to Convolvulus cneorum care, this plant offers year-round visual appeal and seasonal bursts of flowers. By managing common problems, practicing timely pruning, and following the basics of growing, even beginner gardeners can enjoy the beauty and resilience of this stunning silver-leaved shrub.
