Japanese barberry is a popular plant because it’s drought and shade tolerant, and deer resistant. It is, however, also a tick and mouse magnet. In fact, the State of Maine banned Japanese Barberry due to the spread of Lyme disease in Maine. It is also invasive and covered in thorns making it difficult to manage. On its website, the Maine Center for Disease Control says if you have Japanese Barberry in your yard, you should consider removing it. 

Mint is a wonderfully versatile herb and is a great addition to a savory dish, refreshing drink or delicious dessert. However, it’s highly invasive and can spread like a weed throughout your garden.

If you do choose to plant your mint in your garden, give it lots of room to grow and harvest it often.
