Does Native Have Fall Scents?
Native plants are those that occur naturally in a region without human introduction. Many native plants have unique and pleasant scents that become especially prominent in the fall. Fall scents from native plants arise from flowers, leaves, stems, and bark. These rich fragrances serve important ecological purposes, attracting pollinators and seed dispersers. Native fall scents also provide sensory enjoyment for people and inspire use in food, crafts, medicine, and landscaping. This article explores popular native plants with fall scents across North America, examining why these fragrances emerge in autumn and how they vary by region. Appreciating and utilizing native plant scents allows us to connect more deeply with the natural seasonal rhythms of our landscapes.
Popular Native Plants with Fall Scents
Some of the most popular and fragrant native plants that bloom in the fall include Aster, Goldenrod, Witch Hazel, and Joe Pye Weed. These plants fill the autumn air with sweet, earthy aromas.
Aster is known for its cheerful daisy-like flowers that bloom in late summer through fall in shades of purple, blue, pink, and white. Asters give off a lightly sweet, honey-like scent that attracts pollinators before winter. There are many native Aster species across North America that provide color and fragrance in the fall garden (https://abnativeplants.com/collections/fragrant-native-plants).
Goldenrod blooms with fuzzy yellow flower clusters in late summer and autumn. Contrary to popular belief, Goldenrod does not cause fall allergies. It has a pleasant, warm, slightly spicy aroma. Goldenrod grows across North America and provides nectar for migrating butterflies (https://www.loveyourlandscape.org/expert-advice/shrubs-and-flowers/plant-selection/8-plants-for-a-deliciously-fragrant-fall-garden/).
Witch Hazel is prized for its sweet, fruity fragrance in fall. Its spider-like yellow flowers bloom late in the season, sometimes as late as November. The leaves also emit a spicy, earthy aroma when crushed. Witch Hazel is native across eastern and central North America.
Joe Pye Weed blooms with dense, dome-shaped clusters of pinkish-purple flowers from mid-summer into early fall. Its blossoms give off sweet vanilla and spicy anise notes. Joe Pye Weed grows in moist areas across eastern North America and attracts many pollinators.
Why Native Plants Have Fall Scents
Native plants develop rich, robust scents in the fall for several important reasons related to pollination, seed dispersal, and wildlife interactions:
Many native plants rely on insect pollinators like bees, butterflies, and hummingbirds to reproduce. The sweet, strong scents emerging in fall help attract pollinators for last chances at pollination before winter arrives (Fragrant Natives for the Garden). This ensures the plants can produce fruits and seeds that will sustain wildlife over the winter.
The dispersal of seeds is another key reason for fall scents. By spreading their aroma far and wide, native plants can lure animals to eat their fruits which contain seeds, allowing the seeds to then be dispersed through digestion or caching. This scent diffusion helps the plants propagate (Why autumn air smells so delicious and sweet).
Finally, the signature fall scents help wildlife like birds, deer, and bears identify the locations of food sources they rely on. The aromas serve as a signal to congregate in areas where fruits, seeds, and nuts are readily available before winter sets in.
How the Scents Change in Fall
The aroma of fall comes from a complex combination of seasonal changes that affect how plants produce and release scents. Cooler temperatures are a major driver of shifting autumnal aromas. According to an article from The Washington Post, “As temperatures drop in the fall, the molecules responsible for scents slow down. This means they linger in the air longer” (The scent of a season: Explaining the aromas of fall). The cooler air creates ideal conditions for fall scents to accumulate and be easily noticed.
In addition, lower moisture levels in fall concentrate autumnal scents. An article from PBS NewsHour explains that “In the fall, scents can be clearer and more prominent due to the shift in atmospheric conditions” (The science behind the aroma of fall). With less moisture in the air, the aromatic molecules are not diluted as much, making the scents more pronounced.
Finally, day length changes in the fall impact the scent production cycles in many plants. Shortening days serve as a signal for some plants to increase production of aromatic compounds in preparation for winter. This peak in scent output, combined with optimal transmission conditions, is what creates the rich aromatic landscapes of fall.
Regional Differences in Fall Scents
Native plants vary by region, so the fall scents will differ as well. The timing and intensity of the fragrances are also impacted by the climate and weather patterns in each area. Cooler nights tend to make fall scents stronger.
For example, in the Mid-Atlantic region, native plants like Sambucus canadensis (common elderberry) produce lemony-scented white flowers from April to July (https://mgnv.org/plants/best-bets/fragrant/). The changing scents attract regional pollinators like bees, butterflies, and hummingbirds.
In the Southwest, plants like Agastache foeniculum (anise hyssop) give off licorice-like scents in the fall that attract local hummingbirds and other pollinators (https://abnativeplants.com/collections/fragrant-native-plants). The dry climate impacts the intensity of the fragrance.
Native plants and their seasonal scents are specially adapted for local pollinators. Paying attention to the fall fragrances in your area provides insight into your regional ecology.
Using Native Plants for Landscaping
Native plants provide many benefits for home landscaping, especially in the fall when their colors and scents come into full display. Native plants attract native pollinators and wildlife by providing habitat and food sources (https://www.fs.usda.gov/wildflowers/Native_Plant_Materials/documents/intronatplant.pdf). Careful placement of fall-blooming native plants allows you to take advantage of their peak colors and fragrances.
Groupings of native plants with bright fall foliage like sumac, Virginia creeper, and sweetgum can create vivid seasonal displays. Interplanting asters, goldenrods, and Joe-pye weed will add layers of fall-blooming color and scent. Place these groupings where their fragrances can waft into walkways and seating areas. Using native grasses like little bluestem and Indian grass provides color and texture while allowing sightlines to enjoy the floral colors beyond.
By thoughtfully incorporating native plants into your landscape design, you can create an environment that highlights seasonal change while supporting wildlife. Their natural adaptations make native plants excellent low-maintenance additions. Allow native plants space and conditions to showcase their fall riches.
Propagating Native Plants
Native plants can easily be propagated from seed to grow new plants that are adapted to local conditions. The best time to collect seeds from native plants is in late summer or fall when they have fully ripened. It’s important not to deplete natural populations by only collecting a small portion of seeds from each plant. Seeds should be sown outdoors in fall so they undergo natural winter stratification, or can be stored in refrigeration for 30-90 days before sowing indoors. When sowing, lightly cover larger seeds and press smaller seeds into soil without covering. Seeds can be started in containers or directly sown into garden beds. Cover outdoor beds with wire mesh to protect from foraging animals.
Mature native plants can also be propagated by division or cuttings. Dividing plants in spring or fall will create new root masses while maintaining the parent plant. For plants that spread aggressively by roots or rhizomes like some sedges and ferns, division helps restrain growth while generating new plants. Take 3-6 inch stem cuttings from woody plants in early summer when growth is most active. Dip cuttings in rooting hormone and plant in a moist, sterile potting mix to initiate new root growth before transplanting.
When collecting seeds or propagating native plants, it’s critical to preserve genetic diversity within regional ecotypes. Never collect from just one plant. Instead, gather small amounts from many individual plants across a broad geographic area spanning multiple habitats and elevations. This will maintain heterogeneous genotypes adapted to microclimates across the native range. See this guide for more tips on propagating genetically diverse native plants.
Ethical Foraging of Native Plants
When foraging for native plants in the fall, it’s important to practice ethical and sustainable harvesting. Here are some key tips for ethical foraging:
Only harvest abundant plants and leave some behind. Never take the last plant or all of a single species in one area. Foraging selectively helps ensure future regrowth.
Research any regulations on harvesting native plants. Many native species are endangered or protected, so foraging them may be illegal. For example, according to the Gather + Grow blog, American ginseng is protected in many states.
Always get permission from landowners before foraging on private property. Make sure you understand rules about park lands and other public spaces as well.
Following ethical foraging practices ensures native plant communities can continue to thrive. It also allows generations to come to appreciate their unique scents.
Savoring the Scents of Fall
Fall is a perfect time to slow down and appreciate the seasonal changes happening around us. The fragrant blooms of native plants allow us to soak in the smells of the season in a variety of ways.
You can harvest flowers like beebalm (Monarda), sage (Salvia), and lavender (Lavandula) to make teas, herbal sachets, and scented oils that you can enjoy all season long. Drying the flowers or steeping them in oil captures their essences and makes their aromas last (Scents and Sensibilities).
Autumn is also a lovely time to get outside and pair favorite fall activities with native plant scents. Take an evening stroll through a garden filled with fragrant sages and sniff the vanilla-scented flowers. Or sit outside on a brisk day with a cup of mint tea made from native spearmint as the wind ruffles the leaves of nearby spicebush.
Savoring the scents of the season engages all our senses and offers comfort as the days grow colder. Appreciating fall blooms is a mindful way to embrace the natural changes happening around us.
