Another mystery

This large bush in Hilda's garden erupted this week into these golden blooms. I don't know what it is - that's not unusual - it is over 6 ft high, the leaves look a bit like buddleia but the colour and shape of the blooms is not right for that. There is also a honeysuckle twining through it - lovely.
The extra pic shows part of  the profusion of petunias under the window - this was our planting.
