No, fine to do it now - September October are the best times to move things around, although a lot of Hebes are not fully hardy, so perhaps best plant that in the Spring, depending on the variety.

Thanks Bamboo I have not yet bought the Hebe Is there any variety that could be planted now?

Normally I'd say yes and mention a couple - and in fact, I still could, but it probably wouldn't be one you'd want - Hebe ochracea. What's making me be more cautious than in previous years is the forecast for this winter - apparently, if we thought last year was bad, we're in for a shock this year... and taking into account where you live, might be better to err on the side of caution. Even some well established Hebes bit the bullet last year.
