Goldenrod and Aster: Autumn's Harmonious Duo and the Lessons They Teach Us
As the days grow shorter and the air turns crisp, nature unveils one of its most enchanting spectacles: the blooming of goldenrod (Solidago spp.) and aster (Symphyotrichum spp.). These native plants, adorned in radiant golds and purples, transform meadows and gardens into vibrant tapestries that celebrate the season's change.
A Symphony of Colors and Cooperation
Goldenrod and aster often grow together, their contrasting hues amplifying each other's color. This natural pairing isn't coincidental; it's a result of co-evolution that benefits both the plants and the myriad pollinators that depend on them.
In "Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge, and the Teachings of Plants," Robin Wall Kimmerer reflects on this phenomenon. She observes how the companionship of goldenrod and aster enhances the landscape, teaching us about the harmony that arises from relationships in nature. Kimmerer, a botanist and member of the Citizen Potawatomi Nation, uses their relationship to illustrate how understanding and respecting the bonds in nature can deepen our connection with the earth.
Unique Features and Ecological Roles
Goldenrod (Solidago spp.)
Ecological Keystone: Provides crucial late-season nectar for pollinators like bees, butterflies, and wasps preparing for winter.
Misunderstood Allergen: Often wrongly blamed for hay fever, goldenrod's pollen is too heavy to be wind-dispersed; the real culprit is ragweed, which blooms simultaneously.
Soil Enrichment: Its deep roots break up compacted soil and add organic matter, improving soil health.
Aster (Symphyotrichum spp.)
Diversity of Species: With over 180 species in North America, asters offer a range of colors and forms, from the vibrant purple of the New England aster to the delicate blossoms of the white wood aster.
Vital for Migrating Monarchs: Serves as a key nectar source for monarch butterflies during their long journey to Mexico.
Adaptability: Thrives in various habitats, from open fields to forest edges, making it a versatile choice for gardens.
The Magic of Co-Evolution
Goldenrod and aster have evolved side by side, their blooming periods synchronized to maximize mutual benefits. This co-evolution enhances:
Pollinator Attraction: The striking color contrast increases visibility to pollinators. Bees are particularly attracted to the ultraviolet patterns in asters, while butterflies are drawn to goldenrod's rich nectar.
Biodiversity Support: By blooming when few other plants do, they provide essential resources for insects and animals at a critical time.
Genetic Resilience: The shared habitat allows for beneficial soil microbes and mycorrhizal fungi to support both plants, enhancing their growth and resistance to disease.
Pollinators and Wildlife: The Beneficiaries
Honeybees and Native Bees: Rely on the abundant nectar and pollen to build energy reserves for winter.
Butterflies: Species like the monarch, painted lady, and sulphur butterflies feed on these plants.
Predatory Insects: Beneficial insects such as ladybugs and lacewings, which control pest populations, find refuge and food.
Birds and Small Mammals: After flowering, the seeds provide nourishment for birds like finches and sparrows, as well as small mammals preparing for the colder months.
Cultural Significance and Traditional Uses
Both goldenrod and aster hold places of honor in Indigenous cultures:
Medicinal Uses: Native American tribes utilized goldenrod for its anti-inflammatory properties, treating wounds and sore throats.
Symbolism: Asters symbolize love and wisdom in various cultures, often used in ceremonies and as offerings.
Ecological Teachings: Indigenous wisdom emphasizes the importance of these plants in teaching about balance, respect, and reciprocity with nature.
Incorporating Goldenrod and Aster into Your Garden
Embracing these native plants enriches your garden's biodiversity and connects you to the land's heritage.
Gardening Tips
Planting Time: Fall is ideal for planting; the soil is still warm, and the plants can establish roots before winter.
Site Preferences:
Goldenrod: Prefers full sun and well-drained soil but is tolerant of poor soils.
Aster: Thrives in full sun to partial shade with moist, well-drained soil.
Companion Planting: Combine with other natives like black-eyed Susan (Rudbeckia hirta), switchgrass (Panicum virgatum), and purple coneflower (Echinacea purpurea) for a dynamic and supportive plant community.
Maintenance: Both are low-maintenance. Deadheading spent flowers can prolong blooming, and dividing clumps every few years keeps them vigorous.
Environmental Impact
Supports Ecosystem Services: Enhances pollination, pest control, and soil health.
Reduces Chemical Use: Their natural resilience minimizes the need for pesticides and fertilizers.
Water Efficiency: Once established, they require minimal watering, conserving a precious resource.
Why Now Is the Perfect Time
Autumn is when goldenrod and aster shine the brightest. Planting them now ensures they establish well before winter and bloom beautifully next year. Additionally, by planting in the fall, you provide immediate resources for pollinators preparing for the colder months.
