A year or so ago, our family did an email meme. The point of the meme was to answer questions about the person who sent you the email. Several of my sisters said that I would take a bag of compost with me to a desert island. They were right.
After a lot of thought and nashing of teeth, I picked three plants.
First hardy hibiscus.
Third Passion Vine
I picked these three because it just wouldn't be "my" garden without them.
