About Silverbush
Convolvulus cneorum, commonly known as silverbush, is an evergreen perennial shrub prized for its silvery foliage and delicate, trumpet-shaped white flowers. Its compact, rounded growth habit makes it ideal for rock gardens, sunny borders, or as a potted ornamental, adding a touch of luminosity and Mediterranean elegance.
Native range
Mediterranean region, from Spain to Northeast Africa and Western Asia
Care tips
It requires full sun to thrive and maintain its vibrant silvery foliage; insufficient light can lead to leggy growth and fewer blooms. Watering should be moderate, allowing the substrate to dry out completely between waterings, as it is susceptible to waterlogging. It prefers well-drained soils, preferably sandy or stony. Avoid over-fertilizing, as it can promote foliage growth at the expense of flowering and reduce its hardiness.
How to save a dying Silverbush
- Warning signs
- Silvery leaves dull, yellow, or brown, then drop. Stems dry out and become brittle.
- First aid
- Check drainage. If potted, consider repotting to a better-draining container. Prune dead or dry parts to encourage new growth.
- What kills it
- Overwatering combined with poor drainage, leading to root rot. Also, intense cold and prolonged frosts, as it's not very hardy.
- Can it be saved?
- Yes, if roots aren't completely rotted and some green stems remain. Act quickly to correct watering and protect from cold.
