How to Grow Roman Chamomile
Chamaemelum nobile
Roman chamomile is a low creeping perennial (5-15 cm) forming dense, apple-scented mats of feathery evergreen foliage. Unlike German chamomile (an annual), it spreads by runners and lives for years, making it ideal for chamomile lawns, path edges, and between paving. It tolerates light foot traffic and releases fragrance when walked on. Plant in well-drained soil in full sun to light shade, space 15-20 cm apart for groundcover. Hardy to -20 C and virtually maintenance-free once established. Flowers June to August; harvest for tea or deadhead to encourage denser mat growth.
Yearly Lifecycle
Care Essentials
Rarely needed. Roman chamomile thrives in poor to moderately fertile soil. A light compost top-dressing in spring is sufficient on very lean ground.
Watch For
- Aphids on flower stems
- Powdery mildew in humid conditions
- Root rot in heavy, poorly drained soil
Pet Safety
Care Requirements
Light
Full sun to light shade.
Grows best in full sun but tolerates partial shade. In hot climates, afternoon shade prevents scorching. Needs at least 4-6 hours of direct sun for good flowering.
Watering
Moderate; drought-tolerant once established.
Water regularly during establishment. Once rooted, Roman chamomile is quite drought-tolerant. Avoid waterlogging, which causes root rot. In prolonged dry spells, a deep soak every 1-2 weeks keeps plants lush.
Fertilizing
Minimal feeding needed.
Thrives in poor to moderately fertile soil. Over-feeding produces lush foliage at the expense of flowers and weakens the compact habit. A light compost top-dressing in early spring is sufficient.
Pruning
Trim after flowering; mow chamomile lawns.
Shear spent flower stems after blooming to encourage fresh basal growth. For chamomile lawns, mow to 5 cm height 2-3 times during summer. This keeps the mat dense and prevents it becoming straggly.
Overwintering
Hardy to -20 C; evergreen in mild winters.
Fully hardy throughout most of Europe. In very cold regions, a light mulch of straw in late autumn protects the crown. Avoid winter wet, which is more damaging than cold. Good drainage is the best winter protection.
Growing Tips
Perfect groundcover for paths and lawns
Roman chamomile forms dense, fragrant mats that tolerate light foot traffic. Plant 15-20 cm apart and it will knit together within one growing season. The non-flowering cultivar 'Flore Pleno' makes the best lawn.
Divide established clumps every 3-4 years
Lift and divide mature plants in spring to rejuvenate tired patches and fill gaps. Replant divisions immediately and water in well. This keeps the mat dense and vigorous.
Harvest flowers for tea at peak bloom
Pick flowers when fully open and the white petals begin to reflex downward. Dry in a single layer away from direct sun. The apple-scented blooms make a soothing herbal tea.
