I have had a standard version of this for about three years. Can't say it has come to much. In spite of the label saying they are tolerant to -30C new growth on mine had died back each Winter so I've moved it to a spot where it gets the Sun for longer each day and should be a bit better sheltered from any cold winds.
At the moment it has catkins which looked interesting enough for a bit of focus stacking. First I tried taking some hand held photos but they were pretty useless so in the end I set up the 50D with 70-200 zoom lens plus Raynox macro lens with LED ring light on a tripod:
