These plants are not as exotic as you might think

Michelle Obama is planting a vegetable garden on the White House lawn. Good for her.

Says the BBC:

The more exotic plants in the new garden will be arugula, cilantro, tomatilloes, hot peppers and anise hyssop herbs.

That would be rocket and coriander, for British viewers. Of the remaining plants, the first two are basic components of Mexican food, and therefore to be expected in a North American vegetable garden, and the last one is a herb that makes nice honey (the Obamas are also setting up bee hives).

Assuming none of these terms meant anything to you, you could find out what they meant in 15-20 minutes, tops, just by asking Wikipedia.

Wikipedia is by no means a be all and end all; you shouldn’t use it as a definitive source. But you can at least start with Wikipedia, surely?
