Can I grown something over Ivy?

[Thornelius]

My fence which divides mine and neighbours garden is completely covered in Ivy, its about 9 foot tall, I was wondering if I could plant another climbing plant to grow up and over the Ivy to add some colour and flowers as the Ivy is rather boring! Would the Ivy kill anything planted off or could 2 plants climb over a fence happily together?

I have a climbing hydrangea sharing a north-facing wall with a vigorous ivy. It seems to do fine - it seems to attach itself on top of the ivy in places. They were both on the wall when we moved in, so I don't know if they were planted at the same time or in sequence.

I've never heard of climbing hydrangea's before will have to look in to that, thank you! Be good if I can plant something, although the green is better than plain fence the plain green is boring lol.
