Color your world with cut flowers
We all love flowers, both outside in our gardens, and inside in floral arrangements. Carefree and colorful flower arrangements brighten our houses and spirits and bring the outdoors in. Flower arrangements are also wonderful gifts for neighbors and friends.
Many people are dedicating entire beds in their gardens to annual and perennial plants for cut flowers, and some are growing flowers for their own weddings.
Flower arrangements can be formal or exuberant, single color or pastels. Individual blooms range in size and configuration from some of the huge dinner plate-sized dahlias to statuesque, in the case of delphiniums, to delicate and surrounded by ferny foliage like the romantically named love-in-a-mist (nigella). The variations seem limitless.
Over the last few years, small flower farms have been popping up in Sonoma County (check out nbflowercollective.com and sonomaflowermart.com).
Yet, for all of the cut flowers, there are a number of things to keep in mind to grow them successfully.
Many annuals and perennials produce blooms that make for good cut flowers. But they often demand different growing conditions. To grow robust, healthy annuals for cutting, they must be grown in fertile, friable soils, often with compost dug in or used as a mulch. Fertilizer may also be needed. Many perennials need a smaller amount of nutrients than annuals. If your soil is loam, just mulching with an inch or two of compost early in spring is probably all that is needed. Regular irrigation is very important. Annual seedlings and some perennials’ new foliage may need protection from slugs and snails. The correct annuals must be grown in the appropriate season. Cool season or hardy annuals can be planted in the fall or early in the spring to bloom from March through June or later depending on the variety and location. They grow quickly, bloom fast and go to seed in warm, dry weather. Summer annuals are not frost tolerant and should be planted around May 1.
Plants grown for cutting are often planted closely to get a lot of cutting material in a small area, or to force plants to grow upright for long stems. Tall, narrow plants like larkspur or the taller clarkias can be planted at about a 6-inch space between plants. Larger plants like Shirley poppies or white lace flower (orlaya) can be spaced about 10 inches apart. Each species is different, so it’s worth doing some research. Helpful recommendations can be found in the Johnny’s Selected Seeds Catalog johnnyseeds.com. The idea is to fully utilize your bed space for maximum production. Long stems and plenty of them are the goal. Even small plants like violas and pansies are good cut. Growing plants close together causes them to grow more upright rather than low and bushy.
There are so many flower varieties to choose from. How does one make a choice? Seed catalogs offer an incredible array of choices for many flower species and are an easy way to peruse the possibilities. Annual flowers are usually very inexpensive and easy to grow from seed rather than buying plants. If you direct sow seed, you will most likely need to thin the seedlings when they are a couple inches tall. Too crowded plants produce small flowers.
When you think about what to grow, consider the colors you like to use. Some people like a romantic array of pastels or antique-type colors. Others like bright yellows, pinks and purples. Form, size and shape of flowers are important, too. Intersperse larger flowers like giant zinnias with smaller, more elongated flowers for contrast like celosia “Ruby Parfait” and stems of dark leaved basil. Flowers with tall, vertical forms like larkspur, Clarkia unguiculata and snapdragons are wonderful to contrast with daisy type flowers like sunflowers, zinnias and black-eyed Susan. White lace flower (orlaya) is the perfect filler. The soft blue of ageratum flowers look great with white flowers or yellow. Depending on the flower, just one type in a glass vase or bud vase may be all you need. Six or eight poppies in a clear glass vase or a single opulent dahlia in a bud vase is an art form in itself. A whole vase of delicate flowers like agrostemma, nigella, gomphrena or other more delicate flowers is lovely as well. Even the trailing stems of nasturtium are wonderful in an arrangement and last a long time. Whatever the variety, avoid dwarfed plants. They are less robust and stems are very short.
