|Buddleia davidii 'Royal Red'|
Vigorous growing and multistemmed, with long upward and outward arching canes. Large spikes of fragrant Reddish violet flowers on new growth July–September, extremely attractive to butterflies. Most have elongated green leaves which show their whitish or silvery undersides in the breeze.
In most of New England Buddleia are considered "die back" plants because their stems are not fully winter hardy; but they will resprout from buds around their roots each spring. It is perhaps best not to prune before the leaf buds begin to swell in early spring revealing the extent of any winter-killed wood. In colder sites a plant may need to be cut back to just above the ground.
Many have attractive seedpods. Seedlings germinate readily, grow in most any location and can become a nuisance unless removed periodically. Thrives in virtually any reasonably well drained soil. Adaptable to seashore conditions.
