For centuries, lavender has captivated people with its alluring fragrance. University of Missouri Extension horticulture specialists have spent the last three years unlocking the secrets to growing this popular herb in Missouri's diverse climate.
MU Extension's research, led by horticulturist Kelly McGowan, involved test plots across four distinct locations in the state. Their findings offer valuable insights for Missouri gardeners interested in cultivating lavender.
Six lavender varieties – Dutch Mill, Grosso French, Munstead English, Hidcote English, Phenomenal, and Provence – emerged as top performers. Notably, Spanish varieties struggled to survive the state's winters, and high humidity proved detrimental to some cultivars. Soil testing before planting is crucial, and following expert recommendations ensures optimal growing conditions.
Proper drainage is paramount for lavender, a member of the mint family. Raised beds, containers, or high tunnels provide ideal growing environments, protecting plants from excessive rainfall. A well-managed watering schedule that avoids oversaturation is also essential.
In Missouri's colder northern regions, winter protection is necessary for lavender survival. Research by Jennifer Schutter revealed that uncovered plants suffered significant dieback, requiring harsh pruning in spring. Conversely, protected plants thrived, except the Blue Spear cultivar, which is not recommended for northern Missouri.
Standing 1-2 feet tall with silvery green leaves and signature light purple flowers, lavender offers more than just visual appeal. The fragrant oil produced throughout the plant attracts a diverse range of pollinators, including bees, butterflies, and even praying mantises.
This is particularly beneficial in urban areas where natural pollinator populations are declining. Additionally, lavender can deter unwanted insects like fleas, flies, and mosquitoes.
While rewarding, lavender cultivation requires a certain level of attention. MU horticulturist Katie Kammler describes it as "finicky," with some cultivars within the same area exhibiting varying responses. Growers should anticipate a potential 20-25% plant loss each season.
Fortunately, lavender propagation is relatively simple, although certain trademarked cultivars may have restrictions. The strong market demand for lavender extends beyond home gardens. Value-added products like soaps, oils, and balms offer exciting opportunities for those seeking to generate income, according to McGowan.
"With its suitability for small-scale production, lavender presents a wealth of possibilities," says Patrick Byers. Future research by MU Extension will focus on exploring how lavender cultivation can contribute to Missouri's agricultural economy through agritourism and the development of value-added products.
This research by MU Extension empowers Missouri gardeners and potential entrepreneurs to confidently explore the world of lavender cultivation.
