Chamomile – Lawn | Chamaemelum nobile ‘Treneague’. This is the variety of chamomile that you would use to create a “green” lawn. This variety does not flower so you have the green foliage all year round similar to that of lawn grass. Unlike a lot of herbs lawn chamomile does not like stony soil. You must also clear away and weeds or grass. Must be grown outdoors. The leaves can still be used to make tea.
