Buddleia davidii 'Attraction' is a more compact butterfly bush than the usual run of the species, forming a rounded shrub of arching branches lined with gray-green leaves. From summer into fall, royal red, fragrant flowers gather in nodding panicles six to ten inches long, drawing butterflies and bees in profusion.
'Lochinch' is one of the most refined of the butterfly bushes, a cross of Buddleia davidii and the silvery Buddleia fallowiana that takes the best of both: dense, fragrant panicles of soft lavender-blue, each tiny flower lit by a small orange eye, over handsome gray-green, almost silver foliage. Compact and rounded, the shrub blooms all summer into fall on the new growth.
'Miss Ruby' is the butterfly bush that finally cracked the color barrier: a striking, near-sterile hybrid of Buddleia davidii and Buddleia globosa carrying racemes of bright, purplish pink, a magenta few other butterfly bushes can touch. The shrub was bred by Dr. Dennis Werner at the JC Raulston Arboretum in Raleigh, North Carolina, the source of our cuttings.
Endemic to the mountain scrub of Madagascar, where the plant scrambles along slopes between two and six thousand feet, Buddleja madagascariensis throws out long arching canes that will climb to ten feet given a wall to lean on. The flowers come in late winter and spring on terminal panicles up to ten inches long, opening deep yellow and aging through orange to soft pink along the same spike, all of it carrying a honeyed fragrance strong enough to scent a courtyard. The leaves are narrowly ovate, dark green above, silvery and felted beneath, so the whole shrub seems to flicker when wind moves through the canes.
Bejaria racemosa, the tarflower, is one of the odd and lovely surprises of the Florida scrub, a heath-family shrub that looks nothing like the rest of the clan. Where blueberries and azaleas carry small, fused, bell-shaped blooms, tarflower opens wide flowers of seven separate petals, white to soft pink and sweetly fragrant, held in loose summer racemes. The genus honors the eighteenth-century Spanish botanist Jose Bejar, and though older books spell the name Befaria, botanists have since settled on Bejaria.
Crossvine is a vigorous, semi-evergreen native climber that ascends by tendrils and adhesive holdfasts, and var. atrosanguinea is the red one: where the typical crossvine flowers orange, this striking selection, introduced by Woodlanders, carries abundant deep red to red-purple trumpets, often over narrower, longer leaves. The flowers even smell faintly of mocha on a warm day.
Buddleia alternifolia, the fountain or alternate-leaf butterfly bush, stands apart from the usual butterfly-bush crowd. A deciduous shrub native to northwestern China, the fountain butterfly bush is the most cold-hardy of the genus, and is grown above all for a weeping form and an early-season flood of fragrant, lavender-purple bloom.
Buddleia loricata, the mountain sagewood, is a rugged evergreen from the high Drakensberg of South Africa and Lesotho, and one of the hardiest of all the butterfly bushes. Unlike the familiar deciduous buddlejas, this species holds narrow, crinkled, sage-like leaves the year round, dark green above and felted silvery white beneath. The species epithet loricata means clad in mail or armored, a nod to that tough, quilted foliage, while the genus honors the English clergyman-botanist Adam Buddle.
A yellow-flowered butterfly bush, Buddleia x weyeriana 'Honeycomb' is a vigorous hybrid of Buddleia globosa and Buddleia davidii that the late Dr. Michael Dirr judged better than the older 'Sungold'. The plant came to Dirr from Crathes Castle Garden in Scotland, bought as the variety 'E.H. Wilson' but proving to be a very different and superior yellow butterfly bush, named 'Honeycomb' and a standout in Georgia trials, flowering as late as Thanksgiving.
Buddleja salviifolia, the sage-leaf butterfly bush, is a medium to large evergreen shrub from the sun-soaked hillsides of South Africa, and despite the exotic origin the plant has proven remarkably hardy in southeastern gardens, coming through winters at the University of Georgia's Athens trials with quiet resilience.
