Growing Zones 5-9
The incredible jewel-tone blooms of the Royal Red Butterfly Bush (Buddleia davidii 'Royal Red') are not quite a true red color, but purple-red that is radiant in the sun! The flowers are borne at the end of every graceful branch on this beautiful upright-growing shrub!
The Royal Red Butterfly Bush is a vigorous growing shrub that boasts nectar-rich blooms that are an absolute butterfly magnet! It will mature about 4-6 feet in height with an equal spread, often growing from the roots to full size each year in cold climates of USDA planting zones 5 to 9. Snip the blooms for bouquets or deadhead them as they fade for repeat blooms until frost!
With a name like Butterfly Bush, you expect a plant to be attractive to butterflies. In fact, it's more than attractive, it's a magnet for all the bees, beneficial insects, Hummingbirds, and butterflies that pass through your garden seeking nectar! The midday sun diffuses the honey scent into the air and you'll even love the aromatic foliage too! The airy, elegant branching provides fine texture to your landscape with an easy-care nature to go with it!
Planting and Application:
Plant the Royal Red Butterfly Bush near a path or patio and the shrub will provide a delightful fragrance for you, too. Give sun gardens the royal touch as prominent specimens and focal points, mixing and matching with perennials, Roses, and other flowering shrubs beautifully!
The airy branching is friendly screening and property hedges while being tough enough for Rock Gardens! Plant rows to act as graceful backdrops throughout the sun garden, Cut flower garden, and Cottage border!
Every garden becomes a Pollinator Garden with the addition of a Butterfly Bush! Try pairing Royal Red with Purple Emperor or Black Knight Butterfly Bushes for a colorful garden worthy of a King or Queen!

#ProPlantTips for Care:
Generally pest-free, Butterfly Bushes are wonderfully easy to grow! They need the full sun, well-drained soil, and steady water during their first year, but once established, Buddleja (as they can be spelled) are low-water usage but do appreciate supplemental moisture during drought and the summer months to keep the flowers returning until frost. Provide a 3-4 inch deep layer of arborist mulch to support your shrub's root system. This deciduous plant is drought tolerant and not on any deer's list of favorite snacks.
Deadheading keeps the shrub tidier and keeps them reblooming all season! Cut these plants back to the ground in early spring when grown in colder climates because these act more like an herbaceous perennial. For plants grown in warm growing zones, these are woody shrubs that only need an early spring trim will help ensure the best performance and best flowers. Royal Red is hardy, with no significant disease or insect issues.
