Buddleja/Buddleia Davidii, ‘Royal Red’
The Orange-Eye Butterfly Bush, or Summer Lilac is a fast-growing, semi-evergreen shrub that has an upright, stretching habit. Its ability to grow on waste ground, demolition sites, railway-lines and even in the mortar of walls is remarkable. Native to China its natural habitat consists of forest clearings, riverbanks and limestone outcrops. The largest garden specimens can become small trees, but can be kept to a more modest size by pruning. For the healthiest growth it is recommended to soft-prune in late autumn and then hard prune down to your knees in April. Mature Royal Red plants can shoot up to 12 ft before August! Blooms start in summer and continue on into autumn. If deadheaded, flowering will persist until first frost. The highly aromatic honey-scented flowers are highly attractive to butterflies, hummingbirds, bees, and other pollinators.
These 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. (open pollination) Germination tests have confirmed their viability.
‘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 is the plant that made us first fall in love with the Buddleja genus.
