By 'no new growth' do you mean no leaves this year or that it hasn't grown? As you have it in a pot did you protect it from the heavy frosts last winter? Then the usual questions is the pot somewhere wind free, in semi shade and are you watering regularly.

If possible a photo would be useful - you can edit your question and add.

Did you feed it Julier? All plants in pots need regular feeding, and careful attention to watering.
