It looks like my euonymous bush so that's my guess, or a holly bush.

Looks like Euonymus fortunei 'Silver Queen', an attractive shrub, easy to prune to shape. What is your 'spherical bush'?

Yes its a silver variegated Euonymus. They will stand hard pruning so clip it to the shape you want.

Sorry Shirley, being a beginner ( still ! ) it was the best way I could describe it. I'll ask another question and enclose a photo, then you can tell me how to describe it if I ever have a similar question.
Meanwhile, Thanks for the replies guys, maybe I'll leave it.
(,see my next question )

Excellent description, now that I've seen the shrub in question.

Thanks Shirl, you've made my day.

That's good Hank ... well done on cutting the 'invading plants' from your shrub!
