A few years ago, I planted a little seedling of chamomile in the back of my house. Now, they are everywhere in the back yard. All I did was occasionally running the sprinkler.
There are two kinds of this plant. German chamomile that is an annual, Roman chamomile that is a perennial. The German chamomile is the one usually used in tea and herbal medicines. A tea made from fresh chamomile flower tastes much better than commercial one that you can buy in stores.
Unfortunately, mine is Roman chamomile, the perennial one, so I can’t make tea out of the plants. But the little daisy-like flowers are spectacular from June to July and the bloom lasts for weeks.
