Buddleia (Buddleja alternifolia) - Description
Buddleja alternifolia is a species of flowering plant in the family Scrophulariaceae, endemic to Kansu, China, where it grows along river banks in thickets at elevations of 1,500–4,000 m. First described and named by Carl Maximowicz in 1880, the plant was not introduced to cultivation until 1915, by Purdom and Farrer. B. alternifolia was accorded the Royal Horticultural Society's Award of Garden Merit (record 674) in 1993.
Buddleia (Buddleja alternifolia) - Blooming
Bloom times for Buddlejas vary from species to species. Blooms fragrant tubular flowers.
Buddleia (Buddleja alternifolia) - Growth
Evergreen, semi-evergreen, and deciduous shrubs. Some are trees, climbers, and herbaceous perennials. Buddleja grows best in full sun with good ventilation. All species, except climbers, work well in a mixed or shrub border. In frost prone areas, raise Buddleja in a cool greenhouse that has a minimum temperature of 35°F (2°C).
Buddleia (Buddleja alternifolia) - Planting
Sow seeds in spring at 66-75°F (19-24°C). Can propagate from semi-ripe cuttings in summer. Semi-ripe cuttings are cuttings taken from semi-mature wood.
Buddleia (Buddleja alternifolia) - Pest
Butterfly Bushes are susceptible to aphid infestations and should be controlled. Control the infestation by either washing them off with a strong stream of water or by applying Neem oil. Many species attract butterflies.
Buddleia (Buddleja alternifolia) - Interesting facts
As their common name suggests, Butterfly Bushes attract butterflies, but these plants are not limited to just butterflies. Buddlejas also attract bees, moths and hummingbirds. They are notable for their flower color and fragrance. The genus name itself has been a source of confusion. The famous Swedish taxonomist Carl Linnaeus accidentally spelled the genus as "Buddleja". In the common Latin practice used by taxonomists, it would be spelled as "Buddleia". Since Linnaeus never corrected his mistake, the genus is spelled with the letter "j" but is considered to be spelled correctly if spelled with the letter "i" as well.
Buddleia (Buddleja alternifolia) - Soil and irrigation
Butterfly Bushes can generally tolerate many soil-types, but the soil must be well-drained soil. Water freely during the growing season, much less in winter.
