“Greening” up your Valentine’s Day gift

Valentine's Day is one of the most demanding holidays in the cut-flower industry. Consumers struck by Cupid's arrow spend more than $1.9 billion on cut flowers alone. To prepare for the enormous demand for roses, growers produce an estimated 233 million roses, according to an About Flowers research study. 

California Growers Making Changes
While many consumers are thinking about love – few are thinking about the impact the cut-flower industry is making on the environment. Since 1990, California has required the agricultural industry to report on all pesticide use, this includes detailed pesticide reporting for the cut flower industry.

Research shows pesticide use in California cut-flower production declined by almost 50 percent from 2001 to 2010. According to a recent UC Division of Agriculture and Natural Resources (UC ANR) article, there are many reasons for the reduction including increased rules and regulations, early pest infestations practices, a new generation of organic growers and increased public awareness. 

California cut-flower farmers have vastly improved their pesticide use and policies over the past decade. The state currently produces 60 percent of roses sold in the U.S. each year, but growers simply can't keep up with the Valentine's Day surge in demand during the cold winter months when production slows. These factors contribute to a vast majority of the roses sold in February being imported from Columbia and Ecuador. 

Impact of Imported
In a typical year, between 85 percent and 95 percent of the most common fresh cut flowers sold in the U.S. are imported from Colombia or Ecuador, according to an article in One Green Planet.  With fewer restrictions on pesticides in South America, the environmental impact of growing roses in these countries can be devastating.

“To cultivate that perfect rose, growers often resort to chemical weed and insect killers,” Alejandro Boada of Universidad Externado de Colombia states in an article in Organic Bouquet. “Pesticides have been found 300 to 400 meters deep in the soils, which have been unable to filter these poisons. Meanwhile, demand for water has also been found to strain local aquifers, on which other farms depend.”

Not only does aggressive pesticide use in these countries have a destructive environmental impact, their fragile imported roses often have to fly thousands of miles to wholesale warehouses and transported in energy-guzzling refrigerated trucks before reaching the flower shop cooler.

Alternatives for Your Valentine
Don't worry, there are plenty of romantic alternatives with a smaller carbon footprint for your Valentine this year!

• Give a native plant. Native plants thrive in your local environment and provide food for pollinators like bees and butterflies.
• Find a local flower grower in your town using The Association of Specialty Cut Flower Growers online U.S. database. Not only are you supporting a small often-times family-based farm, you are investing money back into your local economy.
• Connect with fresh, beautiful, organically raised flowers using an online database from Local Harvest.
• For a food-lover, potted herbs make a great gift.
• Gardeners love collections of seed packets for a bountiful summer harvest garden.

Zinnias: One of My Favorite Cut Flowers

Zinnias are from the family Asteraceae, and there are many species.  The most familiar, Zinnia elegans, is originally from Mexico, and is therefore sun and heat loving plant that grows up to 3’ high.

They have become one of my favorites for cutting because of their intense and varied colors, which make it perfect for a tabletop vase.

I have them planted right now in one of my 4x4’ mini farm boxes, and they have been doing very well for the past two months after a slow start.  I put in 6-6 packs of the State Fair Mix last May.  The young starts took hold, but showed signs of fertilizer burn for the first 6-8 weeks, which now in retrospect makes sense because of the fresh bagged potting soil they were planted in.  However, now, they have more than compensated for their earlier malaise, as they have almost outgrown their container.  I pick enough weekly to have a fresh arrangement or two for the house, or to give away.  Cuts are made about 12 inches down, but above the side shoots, which will allow new blooms to grow.

This time of year some of the lower leaves have powdery mildew, from too many overcast mornings in Sunset Zone 17, and in spite of hot afternoon sun.  However, this is not a problem, since most of the leaves are stripped when they are brought in for arrangements.

For strictly ornamental garden beds, dwarf zinnias (Zinnia angustifolia) look great for instant color, and also as a butterfly attractant.  They come in brilliant colors of orange, yellow and white, and they are more resistant to powdery mildew.  Mixed with pockets of electric blue Lobelia (Lobelia erinus), they make a stunning garden display.
