A Homes & Gardens gardening report recommends five purple or blue-purple flowers that may provide nectar for hummingbirds during fall migration: Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant. Bloom times and growing conditions vary by species and location, and the report does not quantify how many birds planting them may attract.
Homes & Gardens has highlighted five purple or blue-purple flowers that gardeners can grow to offer hummingbirds nectar during fall migration, when many summer perennials have faded. Its list includes Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant; the report presents them as gardening recommendations, not as a guarantee that planting them will bring more birds to a particular yard.
The report says fall flowers can help fill a seasonal nectar gap as hummingbirds travel south. It recommends choosing plants with tubular blooms and overlapping flowering periods, while matching each species to local conditions. It describes hummingbirds as able to see ultraviolet light and says bold purple and electric-blue flowers can stand out against green foliage. The article does not provide research citations for that explanation or quantify the effect of flower color on visits.
Mexican bush sage (USDA zones 8–10) is described as a shrubby perennial that flowers from late summer into fall, until a hard frost. The report recommends full sun and rich, well-drained soil, with plants spaced 3–5 feet apart. Catmint (zones 3–9) may continue blooming from summer into fall, sometimes through October depending on the variety. Removing spent flowers and leggy growth after the first flush can encourage another bloom, the report says; it advises full sun and well-drained soil and cautions against excess fertilizer, which can cause stems to flop.
Great blue lobelia (zones 4–9) has blue-purple tubular flowers that typically bloom from July through October, according to the report. It prefers moisture-retentive soil and may suit a rain garden. Agastache, also called hyssop or hummingbird mint (zones 5–10), can bloom from early summer until the first frost. The report names ‘Black Adder’ and ‘Blue Fortune’ as purple varieties and recommends full sun; it says established plants should be divided every three to five years. Obedient plant (zones 3–9) bears pink or lavender flower spikes and may flower until frost. It tolerates a range of light and soil conditions but prefers rich, evenly watered soil, according to the article.
Flowers for the Fall Nectar Gap
For gardeners hoping to support migrating hummingbirds, the recommendations offer a way to plan around a seasonal drop in available blooms. Selecting plants with different flowering windows could extend nectar availability in a garden, although the report does not test that outcome or establish how much any one planting changes hummingbird activity. The advice is also relevant to other pollinators: the source says catmint, great blue lobelia and agastache can attract bees and butterflies.
The practical value depends on local climate and care. The listed USDA hardiness zones indicate where plants may generally survive winter, but they do not by themselves confirm that a plant will bloom at the same time or thrive in every yard. Soil moisture, sun exposure, frost timing and plant variety all affect results.

Five Plants and Their Bloom Windows
The source frames its list around a seasonal challenge: many spring and summer perennials have faded by fall, while hummingbirds may still be moving through their migration. It notes that red flowers are widely associated with hummingbird feeders, but argues that purple and blue-purple flowers can also be useful. The report is a garden-advice article rather than a migration study, and its plant descriptions are attributed to Homes & Gardens.
Its five suggestions differ in where and when they may work. Mexican bush sage is suited to warmer zones and is killed back by a hard frost; great blue lobelia prefers wetter soil; catmint is broadly hardy and may rebloom after trimming; agastache offers a long flowering period in suitable sunny sites; and obedient plant is described as adaptable. Those differences make local growing conditions central to applying the recommendations.
“Fall is a trickier time where many perennials have faded.”

What Planting Can—and Cannot—Show
The report does not cite a controlled study, provide counts of hummingbird visits or compare purple flowers with other colors. Its suggestion that these plants can support hummingbirds is gardening guidance, not a measured forecast of increased backyard sightings. It also does not specify a publication date, identify a particular migration route or say how recommendations may vary across local regions beyond the listed USDA hardiness zones.
Bloom dates depend on climate, weather, variety and care; the stated months and frost timing should not be read as guarantees. The source also does not give detailed planting or maintenance guidance for every region. Gardeners should check whether a species is appropriate for their site and local guidance before planting.

Match Planting to Local Conditions
Gardeners considering the recommendations can check their local hardiness zone, typical first-frost date, sun exposure and soil moisture before choosing plants. They can then select species whose bloom periods suit their garden and observe whether flowers remain available as other plants fade. The report offers no scheduled follow-up or subsequent migration data, so any change in hummingbird visits remains something individual gardeners would need to observe rather than a promised result.

Key Questions
Which purple flowers does the report recommend?
It lists Mexican bush sage, catmint, great blue lobelia, agastache and obedient plant. Great blue lobelia is described as blue-purple, while obedient plant can have pink or lavender blooms.
Will planting these flowers guarantee more hummingbird visits?
No. The source offers gardening recommendations but provides no measured visitor counts or guarantee. Hummingbird activity can depend on location, migration timing, weather and available food.
Which of the listed plants blooms latest?
The report says Mexican bush sage and obedient plant can flower into fall, while agastache may bloom until the first frost. Actual timing varies with local conditions and plant variety.
Do the plants all need the same growing conditions?
No. Mexican bush sage and agastache are recommended for full sun; great blue lobelia prefers moisture-retentive soil, while obedient plant tolerates a wider range of light and soil. Check the guidance for the specific species and your site.
