Identity parade #3

You got all the answers last week, so very well done to all who guessed right. We've been at a wholesale nursery, Rochfords, this week looking through their winter stock (generally a fine place, and I was particularly impressed that they do fruit bushes and trees as well as the usual suspects): so our plant idents came from container-grown plants waiting for sale.

Here goes:

1.

(it's only about 2ft high and has a lot in common with the answers to (2) and (3))

2.

3. (it's not the obvious cultivar - look closely at the stem colour)

4. (this shrub was inside the polytunnels and those flower buds open yellow)

5. You should be able to take a stab at nos 2 and 5 without any help from me. Enjoy!
