Chamomile

A fast, easy annual grown for its small daisy-like flowers, the classic source of chamomile tea. Needs light to germinate, so seed goes on the surface, not buried.

Sowing Guide

What you'd find on the seed packet

Sow Depth

Surface sown, do not cover, needs light to germinate

Spacing

15-20cm

Germination

7-14days at 15-18°C

Thinning

Thin to 15-20cm apart once seedlings are large enough to handle

Grower's Note

Keep the compost surface consistently moist until germination, drying out even briefly at this stage often causes seed to fail.

Recommended Varieties

German chamomile (Matricaria chamomilla) is the common annual grown for tea, with abundant, sweeter flowers. Roman chamomile (Chamaemelum nobile) is a low, spreading perennial, better suited to ground cover or a chamomile lawn than to a steady supply of flowers for tea.

Planting Out Guide

Best spaces, conditions and how to plant out

Plant Spacing

15-20cm

Best Grown In

Containers, herb borders, gaps between other plants

Conditions

Full sun. Free-draining soil, tolerant of poor ground once established.

Grower's Note

German chamomile self-seeds readily, once established it often reappears on its own the following year.

Watch Out For

Seed buried too deep won't germinate: chamomile needs light to trigger germination, press seed onto the surface rather than covering it

German and Roman chamomile are easily confused when buying seed or plants: German is a taller annual grown for abundant, sweeter-tasting flowers, Roman is a low, spreading perennial more often used as a lawn or ground cover

Poor air circulation in a hot, humid summer can bring on powdery mildew: space plants generously and avoid overhead watering in the evening

Common Questions

About growing Chamomile in the UK

Why won't my chamomile seeds germinate?

The most common reason is sowing too deep. Chamomile seed needs light to germinate and should be scattered on the surface of the compost, not covered. Keep the surface consistently moist, letting it dry out even once can stop germination.

What's the difference between German and Roman chamomile?

German chamomile is an upright annual that grows quickly and produces abundant flowers with a sweeter flavour, the better choice for a steady supply for tea. Roman chamomile is a low, spreading, mat-forming perennial, more often used as ground cover or a fragrant lawn alternative than grown for flowers.

When do I harvest chamomile flowers?

Pick flowers once they're fully open, usually from early summer, choosing a dry day. Regular picking encourages the plant to keep producing more flowers over several weeks.

How do I dry chamomile flowers for tea?

Spread picked flowers in a single layer somewhere warm, dry and out of direct sun, or use a dehydrator on a low setting. Once fully dry and crisp, store in an airtight container away from light.
