Nandina is another one of those plants like wisteria, privet, and kudzu that was introduced to Mississippi in gardens or for erosion control and liked the situation so well that they decided to go native. A cousin of mine who works in the academics of natural reforestation told me to de-nandina my hill so as not to encourage invasion. I couldn't bear to rip the hundred year old nandina out, but I did dedicate myself to digging all the invading plants outside of my yard, on the fence rows, and woods.
It is difficult to stand firm in my commitment because Nandina is so pretty. In the spring there is new growth and tiny white flowers. In the fall and winter there are red berries and red and green leaves. If my children and the birds leave them alone, the berries are perfect for Christmas decorations. The foliage and leaves will last weeks. If I leave the foliage and berries outside, I get beautiful color in an otherwise bland gardening season. I also provide berries for birds. Of course, they will eat them, then seed a few more plants, which I have promised to uproot.
Why do I like all of the invasive species and find it so difficult to do the right thing?
