You don't need a green thumb to grow Agapanthus -- while they are pretty much a weed they certainly make for an attractive low maintenance corner of the garden. Agapanthus sell for $12 a plant in the nursery -- I've got an untapped fortune down the back!
Reflection:Luke 12:15 (New International Version)
Then he [Jesus] said to them, "Watch out! Be on your guard against all kinds of greed; a man's life does not consist in the abundance of his possessions."
