I am weak in my knowledge of plants, particulery perennials. Also, when it comes to desighn "plant placement" I just don't have the skills yet to know what Looks good where. In my area colerful perennials mixed with other shrubs and trees is becoming the norm for high end landscaping. Can anyone reccomend good books that can be purchased at--say Barnes & Nobels to help learn design skills and help with learning as much as possible about all plants, shrubs and perennials. I know most of the basic shrubs like nandinas, azaleas,and boxwoods by sight, but there are many shrubs and plants I don't have a clue what they are. After cutting lawns for twenty years for people I should know better. I don't want to appear dumb if a customer asks me about a plant.
