Summer Sunflowers
“Keep your face to the sunshine and you cannot see the shadow. It’s what sunflowers do.”
~ Helen Keller
Whether you spot a few lone volunteers or the dramatic vista of an entire cultivated field, it’s easy to smile when greeted by sunflowers! There’s just something about that nubby brown face surrounded by sunny-yellow fringe that captures our attention and triggers our happy reflex…and perhaps, gently signals that summer is winding down and fall pumpkins are on the horizon. I marvel all the new varieties, from the giant yellow-orange seed-filled heads to the petite deep wine-red varieties that bloom all summer long.
Members of the large Asteraceae Family, sunflowers are often referred to as Helianthus, with the most common variety being Helianthus annus, an annual grown by gardeners and farmers throughout the U.S. Often mass-produced commercially in California, especially around the Sacramento area, flower heads are processed for cooking oil, edible seeds, livestock feed and bird seed. And what Farmer’s Market would be complete without bundles of fresh-cut sunflowers for sale? A rustic pail full of yellow sunflowers certainly brings in an essence of the summer country garden.
One of my garden favorites is the hybrid ‘Lemon Queen’ which can grown to 6-8 feet and produces many 2-inch-wide, semi-double, pale yellow flowers with dark brown centers. Not only are they great for cut flowers, they are the “mascot” for The Great Sunflower Project started by Professor Gretchen LaBahn at San Francisco State University. Perhaps one of the simplest projects for citizen scientists to participate in, it’s fun and educational for the whole family. It involves observing sunflowers (or other flowers) in your yard or neighborhood for 15 minutes, and gathering basic data about the pollinators (bees, butterflies, flies) that you notice. Then you input your data on the website (greatsunflower.org) and it joins with the additional data collected by thousands of citizens throughout the U.S. The researchers map this valuable information to direct conservation efforts, especially for the sensitive bees. The data gathered in the past six years is now the single largest body of information about bee pollinator services in North America!
Sunflowers and children just seem to go together like peanut butter and jelly, and one of my favorite books by local author Sharon Lovejoy ( www.sharonlovejoy.com) is aptly named Sunflower Houses. Celebrating the lore of the garden and the joy of interacting with nature, it’s a unique garden lover's collection of memories, poems, activities, and planting projects, including how to plant a summer playhouse with sunflower walls! Drying the giant seed heads can engage kids with the anticipation of a delicious snack or provides a mini-feast for the local birds!
Although I enjoy having a few sunflowers in and around the vegetable and butterfly gardens, I plant water-wise native California sunflowers in the landscape. A hardy performer, Encelia californica is commonly known as Coast Sunflower, California Brittlebush or Bush Sunflower. A small shrub about 3-4 ft. high, it makes a good large-scale ground cover with 2 inch daisy flower. Native from Santa Maria to San Diego, and found locally here in the chaparral, coastal sage scrub and coastal strand plant communities, it doesn’t tolerate a hard frost. Like most natives, a little summer watering will prolong flowering, along with deadheading the exhausted blooms. They look best planted in mass, along with some blue ceanothus or sage to contrast with the yellow flowers and leafy bright green foliage. A variety called ‘El Dorado’ has larger flower heads with overlapping petals. Look for them at native plant nurseries like Manzanita Nursery in Solvang.
Another lovely drought-tolerent native is Canyon Sunflower (Venegasis carpesioides), often found growing in shaded glens and and along stream beds near the coast and hills in lower elevations. A prolific fire-follower, the Mission Canyon area of Santa Barbara was covered with thousands of these shrubby multi-flowered plants, after the Tea Fire eliminated so much of the underbrush. Canyon Sunflower is a rather large perennial with two inch yellow flowers with yellow centers, and look like dahlias on bushes. By pruning to just a few inches after blooming, new shoots will emerge in the next season, and it will also re-seed readily.
No matter what kinds of sunflowers you plant, they are sure to bring a smile and make your summer just a little sunnier. Now grab you hat and gloves, and happy gardening!
