I've got four Caryopteris Chanodensis and they are beautiful in late summer when everything else starts to get brown and bedraggled. Three of these are from a local nursery and were already two years old. They are in an eastern exposure where they get sun until rounghly noon. The fourth was purchased from Spring Hill and took two years to amount to anything. However, it is exposed to the sun virtually all day and has a deeper blue color and a more symmetrical shape than the other three. They do, indeed, seem to thrive in dry conditions. I reccomend them highly -- very easy to care for.

This plant has unusual blue flowers and I have found it to be quite drought tolerant, even in LARGE tubs. pokerboy.
