Roman Chamomile (Chamaemelum nobile, Anthemis nobilis, Family: Asteraceae): Half-hardy perennial, sometimes grown as an annual, to 60cm. Chamomile will grow in full sun in milder climates but prefers partial shade in hot climates. Seeds should be sown in spring, at an ideal temperature of 20°C, and established plants can be divided. Seeds germinate in less than 2 weeks. It may also be propagated by root division. Do not allow the soil to dry out but water well and provide good drainage. Cut back in autumn to promote new growth. Mulch in winter in harsh climates. One variety, C. nobilis ‘Treneague’ does not produce flowers or seeds and is preferred for lawns. Chamomile grows best in a sunny position, in well-drained sandy soil which is slightly acidic, pH 6.0-7.5. It will tolerate light shade. Pull out any seedlings which are unusually tall. These are probably the seedlings of the less desirable German Chamomile (see below). After flowering, cut back to main growth.

German Chamomile (Matricaria recutita, Family: Compositae/Asteraceae) is also known as Sweet False Chamomile. It is the annual form of chamomile, similar in appearance, habits and uses to the Roman Chamomile, though usually taller, about 70cm, its flowers are slightly smaller and they have hollow, yellow central disks. The foliage is not as fragrant but the dried flowers are less bitter than those of C. nobile. It will self seed readily once established.

Here in the subtropics, I tried ONCE to create a small chamomile lawn. It was an abysmal failure - the fierce heat of our sun simply cooked the plants to a crisp! Since that failed attempt, I have always regarded chamomile as a cooler-climate plant.
