Dahlia Fields Forever: How Floret Flower Farm's Erin Benzakein Makes Her Garden Grow

"If there is a heaven, this is what it would look like," says farmer and florist Erin Benzakein. She's describing the sea of dahlias she grows in Washington State's Skagit Valley, where late-summer days start foggy and cool, with plants covered in dew, and the sunrise seems to sprinkle everything in glitter. "When you're in the middle of it, everything else fades away." As she strolls through 93 rows of the plants, harvesting, taking notes, and snapping pictures of specimens, she often comes across bumblebees sleeping right inside the blossoms. That's the wonder of Floret Flower Farm, a family-run operation focused on seed production, breeding, research, and education that is also a thriving seed-and-bulb business (and a 2014 Martha Stewart American Made winner). Says Benzakein, "We wait all year for this window of time."

Fifteen years ago, Benzakein was just a novice gardener. One fall day, she helped a friend dig up her tubers, took some home as a gift, and planted them in her vegetable garden the following spring. The sheer abundance and variety of blooms that popped up a few months later blew her away. "Once you grow them and have a bit of success, you're hooked," she says.

And once you're hooked, the sky's the limit. There are tens of thousands of dahlia cultivars, some as tiny as shooter marbles and others that easily eclipse a dinner plate. Certain plants are so tall, they sway overhead. The flowers can look like water lilies, or daisies, or perfect orbs with petals in mesmerizing symmetry. And their myriad colors are dizzying, ranging from creamy white to deepest burgundy, sometimes within the same blossom. Benzakein grows mother stock of nearly eight hundred different cultivars, and gives tens of thousands of unusual tubers to specialty growers around the country to keep the plants alive and thriving. She also has plans to sell a select group of cultivars she's bred at floretflowers.com.

Unlike lilacs and peonies, whose petals fade shortly after flowering, dahlias remain vibrant and vigorous until the first frost hits, defiantly outlasting every other bloom around. And all the while, they're multiplying underground. "That's what makes them so exciting," Benzakein says. "You plant one tuber and harvest beautiful flowers from it all season, and then you dig it up and there are more. They're buried treasure." Here, Orange 'Beatrice', raspberry 'Sonic Bloom', and coppery 'Hy Suntan' light up Floret Flower Farm.

Happy Returns

Before an arrangement workshop, Erin Benzakein conditions blossoms in her studio, clipping stems and removing leaves that go beneath the waterline. Once dahlias start to flower, she suggests picking them regularly and snipping any that have faded so they don't go to seed. The more you harvest, the more they'll bloom.

Looking for more growing tips? Dahlias do best when they're in well-drained soil and get at least six hours of sun a day. Keep them thoroughly watered and mulched to preserve moisture. Stake individual plants or corral them in rows with twine, as shown, to keep the stems upright. If the ground freezes in winter where you live, dig up tubers after the first deep frost, separate the clumps into individuals, and store them in a cool, dry place to plant next spring.

Sherbet Arrangements

In this sherbet-hued display, 'Ferncliff Dolly', 'Maya', and 'Papageno' dahlias explode among textural 'Cascade' hops, love-in-a-puff vine, mock-orange foliage, and pokeweed.

To ensure a long-lasting bouquet, pick dahlias when they're about three-quarters open, in the mild temperatures of morning or evening. Remove any leaves from the lower halves of the stems, and place them in cool water right away. Let them rest out of the sun for a few hours before arranging. Mix in flower food, and change the water every other day.

'Castle Drive'

Five years ago, an anonymous benefactor surprised Benzakein with a shipment of 20 tubers of 'Castle Drive', an obscure cultivar she'd spent months trying to locate. After careful nurturing, she is now two thousand plants strong, and shares the tubers with select farmers around the country. "If only one or a few growers have a cultivar, and they lose planting stock, that dahlia could be lost forever," she says.
