It is definitely alive!

The 'twig' which I blipped  on March 2nd http://www.blipfoto.com/entry/2019157979017776217 when it was just showing signs of life is now shooting little branches and leaves.
The other three shrubs I bought at the same time are evergreen and two are now showing flower buds, so I was not so concerned about them - I could see they were OK!
I am in danger of losing my reputation as one who can kill even artificial plants ;-)
