Homes & Gardens recommends five purple or blue-purple flowering plants that can offer nectar to hummingbirds during fall migration: Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant. Bloom times and growing conditions vary, and planting these flowers does not guarantee hummingbird visits.
A Homes & Gardens gardening report identifies five purple or blue-purple flowers that may provide nectar for hummingbirds during fall migration, when many summer perennials have finished flowering. The suggested plants are Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant; their suitability depends on local climate, soil and the timing of frost.
The report describes the flowers as a way to help address a seasonal nectar gap, rather than as a guarantee that hummingbirds will visit a particular yard. Its choices include plants with different flowering periods and growing needs. Mexican bush sage and agastache can bloom from late summer or early summer into fall, while catmint may continue a summer display into fall and great blue lobelia typically flowers from July through October. Obedient plant is described as flowering until the first frost.
Growing conditions differ. Mexican bush sage is listed for USDA hardiness zones 8–10 and is recommended for full sun and rich, well-draining soil; the report says to space multiple plants 3–5 feet apart. Catmint is listed for zones 3–9 and prefers sun and well-drained soil. Great blue lobelia, listed for zones 4–9, favors moisture-retentive soil. Agastache varieties ‘Black Adder’ and ‘Blue Fortune’ are recommended for zones 5–10 and full sun. Obedient plant is listed for zones 3–9 and can grow in sun or partial shade and a range of soil types.
The article attributes hummingbirds’ attraction to bold purple and electric-blue flowers to their tetrachromatic vision, which lets them see ultraviolet wavelengths. It also notes that flower shape matters: several recommended plants have tubular blooms or spikes that offer nectar. The report says catmint can also support bees and butterflies, and that great blue lobelia attracts other pollinators. These are general gardening recommendations, not measurements of how many birds a planting will attract.
Flowers for the Fall Nectar Gap
Fall can leave fewer flowering plants available after many summer perennials fade. Adding late-blooming flowers may give migrating hummingbirds another potential nectar source as they move through a region. That is the practical value of the recommendations: gardeners can choose plants whose bloom period and growing requirements suit their yard, rather than relying only on spring and summer flowers.
The advice also broadens the usual focus on red blooms. The source presents purple and blue-purple flowers as options, but color alone does not establish that a plant will draw birds. Local hummingbird species, weather, nearby food sources, the plant’s condition and whether it is flowering at the right time may all affect visits. The report provides no controlled comparison or visitor counts, so its suggestions should be treated as gardening guidance, not a quantified prediction.

Five Plants and Their Bloom Windows
The list combines shrubs, perennials and other flowering plants rather than proposing one universal choice. Mexican bush sage is described as a shrubby perennial with velvety spikes and flowers from late summer through fall, but the source says it dies back after the first hard frost. Catmint is not strictly a fall flower; according to the report, it may extend its summer bloom and can produce a second flush after spent flowers and leggy growth are removed.
Great blue lobelia is a blue-purple native plant with tubular flowers, generally blooming from July to October, and is suited to wetter areas such as rain gardens. Agastache, also called hummingbird mint or hyssop, is described as flowering from early summer until the first frost; the report says established plants should be divided every three to five years. Obedient plant produces pink and lavender flower spikes and can tolerate a range of conditions, though the source says it prefers rich, evenly watered soil.
The source’s USDA zone ranges offer a broad guide, not a guarantee of success in every garden. Conditions within a zone can vary, and local extension services or plant labels can help gardeners check regional suitability. For catmint, the report advises against adding too much fertilizer because it may lead to floppy growth.
“Fall is a trickier time where many perennials have faded.”

Visits Depend on Local Conditions
The report does not give a publication date, identify the locations where the recommendations were assessed, or provide data on hummingbird visits before and after planting. It also does not establish that purple flowers attract more birds than other flower colors. The claims about color vision and plant appeal are presented as general guidance, with no underlying study details in the supplied material.
Whether a plant flowers during migration depends on its variety, local climate, care and the date of the first frost. Hummingbird species and migration timing also vary by region. The article does not specify which species are expected to visit, how much nectar the plants provide, or whether any one option will be suitable in a reader’s garden. Gardeners should check local growing guidance and plant information before choosing.
Choosing Plants for Your Region
For gardeners considering the recommendations, the next step is to compare each plant’s hardiness zone, soil needs and bloom period with local conditions. Where possible, selecting more than one plant with different flowering windows may spread potential nectar availability across the season, although the source does not test that approach or promise visits.
As fall advances, bloom availability will change with colder weather and frost. The source also points readers toward winter preparation, including maintaining hummingbird feeders and learning about overwintering, but it gives no specific schedule or regional instructions in the material provided. Local wildlife or gardening organizations can supply advice tailored to the birds and conditions in a particular area.
Key Questions
Which purple flowers does the report recommend for hummingbirds?
It lists Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant. The flowers vary in color from purple to blue-purple, pink and lavender.
Will planting these flowers guarantee hummingbird visits?
No. The report offers gardening recommendations but provides no visitor counts or evidence that planting a particular flower guarantees visits. Local conditions and whether plants are flowering during migration may affect what birds find.
Which of the plants bloom latest into fall?
The report says Mexican bush sage blooms from late summer through fall, agastache can flower until the first frost, and obedient plant tends to keep blooming until frost. Actual timing depends on variety and local conditions.
Which plant suits a wet garden?
Great blue lobelia prefers moisture-retentive soil, according to the report, and may suit wetter areas such as a rain garden. Its listed hardiness range is USDA zones 4–9.
Do the recommendations apply everywhere?
No. The report provides USDA hardiness zones for the plants, but regional climate, soil and frost timing matter. Check local guidance and plant labels before choosing.
