Some time ago a mother of the bride was lamenting her bride-to-be daughter's objections to lily of the Nile as a wedding flower. "It's just a freeway flower," the daughter said. She was right. Lily of the Nile (Agapanthus) is so easy to grow in California and a few other places that you see it along highways and big commercial landscapes. But in colder climates the same plant -- with its rich blue blooms -- is rare, precious, coveted. There are many other plants that many of us think are too common or too overused to be considered for our gardens. "Familiarity breeds contempt" is the old saying. But if you look with fresh eyes, you might see some great plants that plant snobs love to hate that you might love to grow. There are reasons many of them have been popular for so long and have been used so much. Why not give them a try?
