Natural Garden Defense Seeds

Citrodora Eucalyptus (Eucalyptus citriodora), commonly known as Lemon Eucalyptus or Lemon-Scented Gum, is one of the finest aromatic plants available for patios, decks, porches, and outdoor living areas. Its long, graceful gray-green leaves contain exceptionally high levels of citronellal, releasing a clean lemon-citrus fragrance whenever the foliage is brushed or crushed. Unlike many ornamental plants grown solely for their appearance, Lemon Eucalyptus combines striking beauty with one of the most widely recognized natural insect-repelling fragrances found in the plant kingdom. Easy to grow from seed, it quickly becomes an attractive container specimen that provides fragrance throughout the growing season.

The essential oil extracted from Lemon Eucalyptus has been extensively studied for its insect-repellent properties and is used commercially throughout the world. Rich in citronellal, the foliage produces the familiar fresh fragrance often associated with citronella products, although Lemon Eucalyptus and Citronella Grass are entirely different plants. Simply crushing several fresh leaves releases these aromatic oils immediately. Many gardeners—including us here at Seedman—enjoy keeping container-grown plants beside patios and outdoor seating areas where a few freshly crushed leaves can provide a pleasant citrus aroma while helping discourage mosquitoes, gnats, and other nuisance insects during outdoor activities.

Beyond its aromatic qualities, Citrodora Eucalyptus is an outstanding ornamental container plant. The handsome blue-green foliage provides year-round interest, while the naturally upright branching habit makes it an attractive accent for patios, sunrooms, greenhouses, and bright indoor windows. In frost-free climates it develops into a graceful evergreen tree with small white flowers, while gardeners in colder regions can easily maintain it as a handsome 3 to 5-foot patio specimen by occasional pruning and container culture. The foliage is also excellent for fresh floral arrangements, fragrant bouquets, and dried decorative displays.

Fast-growing, remarkably easy to maintain, and wonderfully fragrant, Citrodora Eucalyptus has become one of our favorite patio plants. Whether grown for its refreshing lemon fragrance, beautiful foliage, container beauty, or traditional use around outdoor living spaces, it offers gardeners a practical and enjoyable way to bring one of nature's finest aromatic plants into everyday life.

Seedman Notes

This is one of our personal favorites here at Seedman. The photograph above shows one of the Lemon Eucalyptus plants growing on our own deck. We purposely keep several container-grown plants beside our patio chairs because simply pulling and gently crushing a few fresh leaves releases an incredible burst of fresh lemon fragrance. Before walking through the woods or working around the farm, we often crush a few leaves and tuck them beneath a cap or into a shirt pocket. While no plant should be considered a complete substitute for commercial insect repellents, we have found Lemon Eucalyptus to be one of the most enjoyable and useful aromatic plants we grow. Combined with its handsome appearance and ease of culture, it has earned a permanent place on our patio every year.

Jackpot Tansy (Tanacetum niveum) is one of the most spectacular flowering perennial tansies available, combining finely textured silver-gray foliage with an astonishing display of brilliant white daisy-like blooms. Introduced from England, this exceptional variety forms an attractive mound of aromatic ferny foliage that becomes almost completely hidden beneath hundreds of cheerful flowers during early summer. Unlike Common Tansy, Jackpot is a well-behaved garden perennial that offers all of the ornamental charm without becoming invasive, making it an excellent choice for borders, containers, and pollinator gardens.

Like other members of the tansy family, Jackpot has long been appreciated for its pleasantly aromatic foliage. For centuries, gardeners have grown tansies around homes, gardens, and outdoor living areas because their naturally fragrant leaves were traditionally believed to help discourage certain nuisance insects. While modern scientific studies show that aromatic plants work best as one part of a diverse, healthy landscape rather than as stand-alone insect repellents, Jackpot remains an excellent companion plant whose fragrant foliage contributes another layer of diversity to sustainable gardens.

From early through midsummer, plants become covered with an incredible display of bright white flowers, often producing several hundred to over a thousand blooms at one time. These nectar-rich blossoms attract bees, butterflies, hoverflies, and numerous other beneficial insects while providing months of outstanding garden color. If trimmed after the first flush of bloom, Jackpot often rewards gardeners with a second flowering in autumn. The silvery foliage remains attractive long after flowering, adding texture and contrast to mixed borders and container plantings.

Easy to grow, remarkably floriferous, and attractive throughout the growing season, Jackpot Tansy is an outstanding perennial for gardeners seeking beauty and function in the same plant. Whether admired for its elegant silver foliage, masses of white blooms, pollinator value, or traditional reputation as an aromatic companion plant, it is one of the finest ornamental tansies available for modern gardens.

If you're looking for a perennial that combines ornamental beauty with the philosophy of Natural Garden Defense, Jackpot Tansy is an outstanding choice that demonstrates how healthy gardens can also be incredibly beautiful.

Mountain Tobacco (Nicotiana attenuata) is one of North America's most remarkable native tobaccos, valued for centuries by Indigenous peoples for ceremonial, cultural, and practical purposes. This graceful annual produces slender stems topped with attractive yellow-green tubular flowers above soft gray-green foliage, creating an elegant ornamental plant that blends beautifully into native gardens and wildflower plantings. While its delicate appearance suggests otherwise, Mountain Tobacco is naturally rich in nicotine, one of the plant kingdom's most effective natural defensive compounds.

Long before the development of modern pesticides, gardeners commonly relied upon tobacco as a natural source of insect control. Dried tobacco leaves were ground into tobacco dust or steeped to produce tobacco teas that were applied to ornamental plants and garden crops. The naturally occurring nicotine found in the leaves acts as a powerful insect neurotoxin, and for many decades tobacco dust was a standard product found in garden centers throughout North America. Although commercial nicotine-based insecticides have largely disappeared because of modern safety standards, Mountain Tobacco remains an interesting reminder of one of gardening's oldest natural pest management tools.

Beyond its historical value, Mountain Tobacco is an attractive ornamental that performs well in sunny locations with well-drained soil. The flowers are visited by hummingbirds and several native pollinating insects, while the plant itself serves as an important component of native western ecosystems. Its compact size makes it suitable for wildflower gardens, native landscapes, educational gardens, and collections illustrating traditional Indigenous and historical horticultural practices.

Today, Mountain Tobacco is appreciated as much for its fascinating history as for its ornamental beauty. Whether grown to explore the history of natural gardening, to preserve an important native species, or simply to enjoy its graceful flowers, it offers gardeners a unique opportunity to cultivate one of the plants that helped shape the early history of organic pest management.

Seedman Notes

Mountain Tobacco has long been one of our favorite historical garden plants. Years ago, tobacco dust was a common sight in garden centers, and many experienced gardeners relied upon it as a natural insecticide before modern products became widely available. Here on our own farm, we've found that finely powdered dried leaves can provide good knockdown of late-season stink bugs when used carefully around garden plants, particularly when we prefer to avoid conventional pesticides near vegetables close to harvest. Because nicotine is a powerful naturally occurring insecticide, we recommend handling the plant with care and viewing it as part of gardening history rather than as a substitute for modern, labeled pest-control products.

Osage Orange (Maclura pomifera) is one of North America's most remarkable native trees, valued for its legendary wood, brilliant yellow fall foliage, thorny natural hedges, and unusual grapefruit-sized green fruits known as hedge apples. For more than a century, homeowners have placed these distinctive fruits in basements, barns, crawl spaces, and around foundations because of their long-standing reputation for discouraging spiders and household insects. While the folklore surrounding hedge apples has been debated for generations, modern scientific research has revealed that the fruits contain naturally occurring compounds with genuine insect-repellent potential.

Researchers studying Osage Orange have identified several aromatic compounds within the fruit, including elemol, that demonstrate significant insect-repellent activity under laboratory conditions. Studies have shown purified elemol to be effective against mosquitoes and other insects, with some tests reporting repellency comparable to conventional products. Although simply placing whole fruits around a home has produced inconsistent scientific results, the discovery of these naturally occurring compounds has confirmed that the centuries-old reputation of Osage Orange was based upon more than simple folklore. Today the tree continues to attract interest as a source of naturally derived insect-repellent chemistry.

Beyond its fascinating chemistry, Osage Orange is an outstanding landscape tree with an equally impressive history. Before barbed wire was invented, its dense thorny branches formed nearly impenetrable living fences across the American prairie. During the 1930s it became one of the signature trees planted throughout the Great Plains Shelterbelt Project to reduce wind erosion and protect farmland. Its exceptionally dense yellow-orange wood is among the strongest and most rot-resistant native hardwoods in North America and has long been prized for fence posts, tool handles, and some of the finest traditional archery bows ever crafted.

Easy to grow and highly adaptable, Osage Orange thrives in poor soils, drought, heat, and difficult growing conditions where many other trees struggle. Whether planted as an ornamental specimen, wildlife tree, historical landscape, or simply to appreciate one of nature's most interesting examples of plant chemistry, it remains one of America's most distinctive native trees.

Natural Properties

• Fruits contain naturally occurring compounds including elemol that have demonstrated insect-repellent activity in scientific studies.
• Research continues to investigate Osage Orange as a potential source of naturally derived insect-repellent compounds.
• The traditional practice of placing whole hedge apples around homes remains popular, although scientific studies have produced mixed results.
• Excellent wildlife and shelterbelt tree.
• Outstanding drought tolerance and adaptability.
• Historically one of America's most important living hedge plants.

Seedman Notes

Osage Orange is one of those fascinating plants where traditional gardening and modern science unexpectedly meet. For generations people placed hedge apples around homes hoping they would discourage insects. While simply placing the fruits around a room has not consistently proven effective in scientific studies, researchers have since identified naturally occurring compounds within the fruit that genuinely possess insect-repellent properties. We think that's a wonderful reminder that old gardening traditions sometimes contain more truth than first meets the eye, even if modern research helps explain them in a different way.

Catnip (Nepeta cataria) is far more than a favorite treat for cats—it is one of the most scientifically studied aromatic herbs for natural insect deterrence. A hardy perennial in the mint family, Catnip produces soft gray-green foliage rich in fragrant essential oils and attractive spikes of white flowers lightly spotted with lavender. Easy to grow and remarkably adaptable, it has long been cultivated in herb gardens for culinary, medicinal, and ornamental purposes. Today it is equally appreciated for its exceptional value to pollinators and the naturally occurring compounds found within its aromatic leaves.

The secret behind Catnip's remarkable reputation is nepetalactone, the primary essential oil produced in its foliage. Numerous scientific studies have demonstrated that this naturally occurring compound possesses significant insect-repellent properties against mosquitoes and several other nuisance insects. The greatest concentration of fragrance is released when the fresh leaves are gently crushed, making Catnip a popular herb for planting near patios, walkways, and outdoor seating areas. While the living plant itself should not be expected to eliminate mosquitoes from an entire yard, the aromatic foliage has earned Catnip a well-deserved reputation as one of nature's most effective insect-repelling herbs.

Beyond its insect-repelling qualities, Catnip is an outstanding pollinator plant. Its long-lasting blooms provide nectar for honeybees, native bees, butterflies, and numerous other beneficial insects throughout the summer months. The vigorous plants are drought tolerant once established, easy to grow in a wide range of soils, and readily fit into herb gardens, pollinator borders, cottage gardens, and containers. Of course, many cats find the fragrant foliage irresistible, making it equally popular with gardeners and their feline companions.

Whether grown for its traditional herbal uses, scientific interest, pollinator value, or aromatic foliage, Catnip remains one of the most versatile herbs available to home gardeners. Few plants combine ornamental beauty, wildlife value, and documented natural insect-repelling properties as successfully as this classic garden favorite.

Seedman Notes

Catnip is one of the cornerstone plants in our Natural Garden Defense collection because it combines outstanding scientific research with centuries of traditional herbal use. The same aromatic oils that make the plant irresistible to many cats are responsible for its well-documented insect-repelling properties. Here at Seedman, we recommend thinking of Catnip as another valuable partner in creating a healthier outdoor environment. Plant it near patios, herb gardens, or seating areas where the fragrant foliage can be enjoyed, gently crush a few leaves to release the essential oils when desired, and let the flowers support the bees, butterflies, and other beneficial insects that every healthy garden needs.

Rosemary is a classic Mediterranean herb prized for its fragrant, needle-like leaves and rich, savory flavor. This attractive evergreen herb is excellent for seasoning poultry, meats, roasted vegetables, breads, soups, and herbal blends. Its upright, woody growth also makes it a beautiful container plant for patios, porches, herb gardens, and sunny windowsills.

Rosemary grows best in full sun and well-drained soil. Once established, plants are drought tolerant and prefer slightly dry conditions rather than wet soil. In warm climates, rosemary can be grown outdoors year-round, while gardeners in colder areas often grow it in containers and bring it indoors during winter.

Small blue to lavender flowers may appear on mature plants, attracting bees and other beneficial pollinators. With its evergreen foliage, pleasant fragrance, and culinary value, rosemary is one of the most useful and rewarding herbs to grow.

Rosemary is generally hardy in USDA Zones 8-11. In colder zones, grow as an annual or in a container that can be moved indoors before freezing weather.

• Start seeds indoors 8-10 weeks before the last expected frost.
• Sow seeds lightly on the surface or cover very thinly with seed-starting mix.
• Keep soil warm, around 70-75°F, and lightly moist but never soggy.
• Germination is naturally slow and uneven, often taking 14-28 days or longer.
• Provide bright light once seedlings emerge.
• Transplant outdoors after all danger of frost has passed and plants are well established.

• Plant in full sun for best flavor and growth.
• Use well-drained soil or a container mix with good drainage.
• Avoid overwatering; rosemary dislikes wet roots.
• Trim regularly to encourage bushy growth.
• Harvest sprigs as needed for fresh use, or dry leaves for later use.

Wormwood (Artemisia absinthium) is one of the oldest and most respected aromatic herbs in the world, valued for centuries for its striking silver-gray foliage, intensely fragrant leaves, and remarkable natural chemistry. A hardy perennial native to Europe and western Asia, Wormwood forms attractive mounds of finely divided foliage that provide beautiful contrast in herb gardens, perennial borders, and cottage landscapes. While many gardeners recognize Wormwood as the famous herb historically associated with the European beverage Absinthe, its long history as a natural companion plant and insect-deterring herb is equally fascinating.

The aromatic foliage contains naturally occurring compounds including thujone, absinthin, and other essential oils that give Wormwood its distinctive fragrance and intensely bitter character. For generations, dried leaves and fresh sprigs were placed in cupboards, wardrobes, animal bedding, and around homes to help discourage moths, fleas, flies, and other nuisance insects. Modern research continues to investigate the insect-repellent properties of Wormwood's essential oils, supporting many of its traditional uses. While the living plant should not be expected to eliminate insect problems on its own, it remains one of the classic aromatic herbs grown as part of an integrated approach to natural gardening.

Beyond its practical uses, Wormwood is an exceptionally attractive ornamental perennial. Its soft silver foliage provides outstanding texture throughout the growing season and complements flowering perennials with contrasting color and form. During midsummer, airy sprays of small yellow flowers appear above the foliage, while the aromatic leaves continue to provide fragrance long after flowering has ended. Once established, Wormwood is highly drought tolerant and thrives in sunny, well-drained locations where many other perennials struggle.

Easy to grow and remarkably long-lived, Wormwood offers beauty, history, and practical value in one elegant plant.
