California continues to be the leading state with floriculture crops valued at $1.08 billion. Florida, the next largest producer, was up 12 percent from the prior year to $1.03 billion in wholesale value. These two states account for 49 percent of the total value of the top 14 producing states. In addition to California and Florida, the other leading states in floriculture production include Illinois, Maryland, Michigan, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Texas, and Washington.

Michigan, Texas, California, North Carolina, California, and New Jersey are the top five states in this category and accounted for 67 percent of the top states in total bedding and garden value in 2015. (NASS 2016)

Production of potted flowering plants for indoor or patio uses was valued at $810 million in 2015. Orchids continue to lead this category with $288 million, up 5 percent from 2014. The value of potted Poinsettias was $140 million, down 3 percent from the previous year, along with the wholesale value of Easter lilies, which was down 8 percent.

The value of foliage plant sales in 2015 was $714 million, up 15 percent from 2014. Florida continues to lead in foliage plant production with 76 percent of the total value.

The wholesale value of domestically produced cut flowers was $374 million for 2015, up 3 percent from 2014. California's is the US leading producer of cut flowers with a wholesale value of $294 million, accounting for 78 percent of the total cut flower value of the other leading states.

Marketing

The 2009 Census of Horticultural Specialties, a survey conducted every 10 years, determined the primary outlets for floriculture products were retail garden centers and nurseries (19 percent), other mass marketers (17 percent), direct to consumer sales (16 percent), landscape contractors (14 percent) and superrmarkets (7 percent).

andre [41]
What are you asking? Slope? If so. You would do change in y over change in x. So subtract 2 and -4 to get positive 6, then subtract 6 and -3 to get positive 9. Your slope is either 1/3 if it’s increasing, or negative 1/3 if it’s decreasing.
