Buddleia (Butterfly Bush) – davidii ‘Royal Red’

A must for your butterfly garden!
‘Royal Red’ features spike-like 6-14″ long terminal clusters of magenta-purple flowers, which bloom from June to September and sometimes to first frost. The foliage is a fresh willowy gray-green. Lightly scented, Buddleias attract butterflies (and hummingbirds) like a magnet. Popular fresh cut flower. ‘Royal Red’ is an Award of Garden Merit (AGM) holder. Also a Royal Horticultural Society of Great Britain Award of Garden Merit plant. Tiny individual flowers are produced in profusion in long, dense trusses. This award-winning variety is noted for being full of vigor and very floriferous. It has a compact, upright habit. Great late summer color. In cooler zones, Buddleias die back to the ground each year, sending up a dense group of new shoots in late spring that quickly develop into a large shrub.

Butterfly bush is a deciduous to semi-evergreen shrub with a weeping form that can get 6-12′ tall and have a spread of 4-15′. Butterfly bushes have opposite, 6-10″, lance-shaped gray-green leaves on long arching stems. The tiny flowers are irresistible to butterflies. They are borne in long, 8-18″, cone-shaped clusters that droop in a profusion of color and stay abuzz with winged, nectar-feeding insects from late spring until first frost in autumn. The flower clusters can be so profuse that they cause the branches to arch even more. The flowers of many cultivars are sweetly fragrant.

General Information +

Botanical: Buddleia davidii 'Royal Red'

Common: Butterfly Bush

Family: Loganiaceae

General Characteristics: This butterfly bush cultivar is a deciduous shrub with an arching, spreading habit which typically grows 6-8' tall if not cut back in late winter and 4-5' tall if cut back. Easily grown in average, medium, well-drained soil in full sun. Becomes weedy and sparse with diminished flowering performance if not grown in full sun. Does poorly in wet conditions. In USDA Zone 5, this plant will often die to the ground in winter and therefore is often grown therein in the manner of an herbaceous perennial. Even if plants do not die to the ground in winter, they usually grow more vigorously, produce superior flowers and maintain a better shape if cut to the ground in late winter each year. Removal of spent flower spikes during the growing season will encourage additional bloom, but consider leaving final blooms in place to facilitate reseeding.

Tip: Cut faded flowers off a butterfly bush regularly to keep it blooming throughout the summer. Butterfly bushes prefer full sun (they must receive eight or more hours of sun a day to thrive).

Use: Provides valuable summer and early fall flowers when few other shrubs are in bloom. Best grown in massed plantings in borders, cottage gardens rose gardens or butterfly gardens. Usually does not make a good single specimen shrub.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. Nematodes can be troublesome in the South.

Planting Instructions: May be planted in any well-drained soil. This plant tolerates some drought and wetness. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly.
