Caryopteris clandonensis 'Thetis'

Caryopteris Thetis comes into flower just when most garden plants have shed their last petals. In September and October, exquisite lavender panicles appear on top of upright stems, attracting clouds of bees and butterflies. Apart from colourful flowers, this bluebeard also has slender and aromatic grey-green leaves.
Growing no more than 1m tall, Thetis is a compact shrub, very well-suited for mass planting or container gardening. She likes full sun or partial shade.
