Buddleja alternifolia
alternate-leaved butterfly bush (syn. buddleia)
This shrub is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.
The arching branches of this graceful flowering shrub are festooned with clusters of fragrant, lilac flowers, in June that are highly attractive to butterflies. A perfect focal point plant for a sunny border, it's often grown as a standard. In autumn the pointed, dark green leaves turn an attractive shade of yellow.
