Egyptian Starcluster

You're welcome, elime. :)
artistatheart, I love this plant but it doesn't grow well for me, so I don't use it very often at work! It's one of those I know the name begins with 'P' but always have to look up! (And thanks, it's a nickname I picked up from work. :) )

Good work Dangermouse. ( By the way....I love your username.)

Thanks Dangermouse!

Definitely not lantana, or verbena. Took me ages to remember the name of these as I don't see them very often. But if you look at the link, and here too (http://en.wikipedia.org/wiki/Pentas) I think you'll find it's a pentas. :)

This appears to be some sort of Verbena or Lantana from looking at the shape of the leaves, the way that are attached to the stem and the five petaled flowers in clusters.
