Buddleja/Buddleia Davidii, ‘Royal Red’
The Butterfly Bush, also known as Orange-Eye Butterfly Bush, or Summer Lilac, is a fast-growing, semi-evergreen to evergreen shrub that has an upright, stretching habit. Native to China, its natural habitat is in forest clearings, riverbanks and limestone outcrops. Its ability to grow on waste ground, demolition sites, railway-lines, and even in the mortar of walls is remarkable.
These open-pollinated Buddleja Davidii ‘Royal Red’ seeds (sometimes also marketed as ‘Burgundy’ in the US) quickly grow into plants with long, arching branches with endless spires of massed, fragrant flowers in various colors of red/cerise, bright magenta, purples, and lavenders (no white). Most of them will resemble the ‘Royal Red’ parent from which the seeds were obtained. Germination tests have confirmed their viability.
For the healthiest looking growth and best plant structure, it is recommended to soft-prune Butterfly Bushes in late autumn to prevent winter wind-rocking (damages roots), and then in April hard prune down to your knees. Even with pruning… or maybe we should say especially because of pruning, established plants will reach 10-12 ft by August! Blooms start in summer and continue well into the first frost, with dead-heading.
The highly aromatic, honey-scented flowers are highly attractive to butterflies, hummingbirds, bees, and other pollinators.
‘Royal Red’ was accorded the Royal Horticultural Society Award of Merit in 1950, and the Award of Garden Merit in 1993. It was reaffirmed again in 2010. ‘Royal Red’ has become one of the most successful Buddleja cultivars of all time, and still regarded as the best of the older ‘reds’.
This was our first Buddleja davidii plant and the one that made us fall in love with the Buddleja genus!
