Plant ID please

I'm not much cop on flowery stuff but a larger photo might help. The system now lets you put large photos on and resizes them on the server.

I thought a Hebe as well, or maybe a Euphormium (is that how you spell it ?)  I have seen the latter planted in pots to trail over the side, but if it is beware of the white stuff inside it, in can cause severe allergies.
