Caryopteris x clandonensis 'Grand Bleu'
Bluebeard 'Grand Bleu'
This is a small, deciduous shrub with grey-green leaves and produces clusters of blue flowers in late summer. There are several cultivars with flowers in shades of blue or white. If planted in colder climates, the stems can die back in winter, especially on heavy soils. They prefer well-drained, sandy soil in full sun anf the leaves have a fragrance like eucalyptus, especially when lightly bruised. 'Grand Bleu' has a delightfully rounded habit that forms a neat deciduous shrub in mixed borders. Perfect for adding a splash of late season colour.

Planting
From Early Spring TO Late Autumn
Plant in spring or autumn. Caryopteris flowers best and its leaves develop their lavender fragrance most powerfully when it is grown in an open, sunny position. It is best on light soil or where the ground is interlaced with the outreaching roots of other woody plants and therefore drains quickly after rain.
Flowering Season
From Late Summer TO Early Autumn
Caryopteris produces flowers at the end of shoots and in the leaf axils through late summer and into early autumn.
Propagation by cuttings
From Mid Summer TO Mid Summer
These bushes are easily reproduced from cuttings taken in mid-summer. Use unflowered shoots and remove their slender tips and the lower leaves, making the cut immediately beneath a node. Dip the prepared cuttings in hormone rooting powder and set them in small pots containing a 50:50 mixture of soilless compost and Perlite. Then cover with a plastic bag and keep in a light position. In three to four weeks, successful rooting will be indicated by small buds breaking near the top. The rootlings should then each be given pots of their own and kept in a frame or under a cloche for planting out the following spring.
